Fire Emblem: Three Houses/Unused System Text

This is a sub-page of Fire Emblem: Three Houses.

There is an absolute wealth of text relating to abandoned gameplay and system features.

Focuses

Multiple strings allude to an earlier "focus" system, in which you would select one of the eleven skills as the area of focus for a month's lessons. Skill experience gained by instruction would be boosted for that one skill as long as the focus was in effect; the efficacy of these focuses would have increased with your professor level.

amiibo Messages

These unused strings seem to imply that the game's amiibo compatibility features originally would have worked somewhat differently.

Text (JP)	Text (EN)	Notes
amiiboプレゼント！ (name)を獲得した	amiibo present! Received (name).	In the final game, the item rewards for scanning amiibo appear as collectible spawns around the amiibo gazebo that must be picked up manually, rather than being delivered directly by the scanning process like in these messages.
amiiboプレゼント！ (name)を(n)個、獲得した	amiibo present! Received (name) x (n).
今日はもうこのキャラクターのamiiboで プレゼントはもらえません	You can't receive any more presents from this amiibo character today.	In the final game, there is no limit to the amount of amiibo you can scan, though only the first one used affects the items received. This five-presents-a-day scenario matches the way amiibo rewards work in Fire Emblem Warriors, though the messages that game uses for these situations are worded differently.
amiiboプレゼントは １日に５回までもらえます	You can receive amiibo presents up to five times per day.
このamiiboは 「ファイアーエムブレム 風花雪月」 には対応していません	This amiibo is not compatible with Fire Emblem: Three Houses.	The only Fire Emblem game that's compatible with some amiibo but not all of them is Fates, though the message that game uses for this situation is worded differently.

Cut Group Tasks

While the final game only has four used group tasks, it seems that more were planned. Unlike the used ones, none of these specify skills that would improve by doing them.

Name (JP)	Name (EN)	Description text (JP)	Description text (EN)
釣り池の管理	Fishing Pond Management	釣り池の水質管理や餌やりを協力して行う	Work together to manage the water quality of the fishing pond and feed the fish.

食料調達	Food Procurement	近隣の森で採集や狩猟を協力して行う	Work together to forage and hunt in the nearby forests.

Alternate Activity Points Scheme

In the final game, the player is given a maximum of 10 activity points each week to spend on using monastery facilities. However, some text strings suggest that an alternate scheme was planned in which more activity points would be available, but would be consumed by many more activities, and would be counted on a per-month basis rather than a per-week basis.

The name and description strings for types of special event days on the ingame calendar include some unused or unseen meal- and choir-related events.

This batch of strings, located in another file, would have been for the locations to trade with themselves. The English script has a handful of typos, odd capitalisations and inconsistencies with the final game script, and elected not to translate the latter entries.

Notes:

• Another alternate English name for what the final game calls Morfis! Additionally, "Regan" is called Riegan in the final English script.
• "Gwydion" may be an early name for the Gideon region of Faerghus, as seen on the early world map in the E3 2018 trailer (which also uses the "Regan" label). Kupala is only otherwise referenced in DLC-related content added in the Version 1.2.0 update on February 13, 2020, and "Miach" is not mentioned at all in any part of the final game.

Directions/Mounted Training

There are a number of strings which seem to be describing different permutations of the same concept: a series of hunting and training expeditions, often suggested to involve riding on horseback. How related they really were is anybody's guess, but for convenience's sake they're being lumped together here. Rewards evidently may have included training in proficiency in focused areas of some sort, and/or hunting wild game.

Notes:

• The rest of the English script spells the mentioned mountain range as "Oghma", not "Ogma" (possibly to not step on the toes of the important Archanean character), suggesting the translated strings were left alone after an initial pass.
• The Itha region is only mentioned once in the entire final game, in the library's history of House Blaiddyd as the home of Dimitri's regent, Rufus.

Horse Raising

There are very few surviving text strings that relate to this feature, and as such very little information on what it could have entailed. In the final game, there is no way whatsoever to interact with or customize horses; no Fire Emblem game has ever had anything in that vein either, but Shouzou Kaga's post-Fire Emblem game, Berwick Saga, did feature a variety of equippable horses with different stats.

Text (JP)	Text (EN)
馬育成	Horse Raising
騎乗訓練が終わりました 報告を聞きに行きましょう	Training of the stable horses is complete. Visit the stables for new information.
「馬育成」はまだ解放されていません	Horse Raising isn't unlocked yet

Sauna

A handful of strings imply that the Sauna could originally be explored freely (in the final game, it can only be interacted with through menus), and had gender-based divisions.

Text (JP)	Text (EN)
浴室前へ	Exit Sauna
男湯入り口⇒男湯へ	To Men's Baths

Tournament

There are a handful of unused strings mixed in with the used arena ones that suggest other features were intended for it, some of which sound similar to how arenas worked in past Fire Emblem games.

Text (JP)	Text (EN)	Notes
参加費	Entry fee	An entrance fee, similar to arena wagers in the majority of Fire Emblem games, was intended.
(blank)	Select tournament difficulty	Strings for selectable levels of difficulty. The Coliseum mode in Fire Emblem Heroes has a similar feature.
初級	Beginner
中級	Intermediate
上級	Advanced
大会の難易度を選択してください	Select a difficulty level for the tournament.
対戦相手は強くないので気軽に参加できる ５戦勝ち抜くと(n)Ｇ得られる	Your opponent is not strong so you have no worries taking them on. Win through 5 battles and get (n)G.

死線をくぐり抜けた猛者たちが参戦している ５戦勝ち抜くと(n)Ｇ得られる	Incredible warriors who have survived deathly battles are taking part. Win through 5 battles and get (n)G.
使用する武器を選択してください	Select a weapon to use.	A string suggesting the ability to choose one's weapon for tournament rounds, similar to the Fire Emblem: Seisen no Keifu arenas, was considered.
お金が不足しているため 武闘大会に参加できません	You can't take part in the Fighting Tournament because you don't have enough money.	Another entry fee reference.
武闘大会に仲間を参加させますか？	Do you want your friends to participate in the Fighting Tournament?	This one is juuust vague enough that there's no way to be sure who they meant by "friends"/"仲間".
(name)のやる気がアップしました また大会報酬として(n)Ｇを得ました	(name)'s motivation went up. They also got (n)G as a tournament reward.	In the final game, tournaments have no effect on a unit's motivation (though the menu for selecting a unit to participate still displays their current motivation, perhaps as a relic from this stage of development).
初戦敗退したので報酬はありませんが (name)のやる気はアップしました	You lost the first match so there is no reward, but (name)'s motivation went up.
(name1)と(name2)の 戦闘が終わりました	The bout between (name1) and (name2) is over.	This set isn't too interesting aside from calling the tournament rounds "bouts"/"戦闘", which isn't seen anywhere else.
戦闘に敗北したため、ここで敗退です	Your fighter lost the bout and has been eliminated from the competition.
すべての戦闘に勝利しました！	You won all the bouts!

Cooking

Two additional features were intended for the meal preparation activity: some sort of method of keeping the meals for later use rather than consuming and benefiting from them immediately at the monastery, and an alternate option to cook alone as a counterpart to cooking with an ally. (These "Cooking Alone" strings are also accompanied by strings specifying "Cooking Together"; in the final game, these were often replaced with strings just generically calling it "cooking" due to a lack of need to tell two different cooking modes apart.)

Text (JP)	Text (EN)
仲間と料理	Cook with Partner

Unused Dishes

There are surviving text assets for a total of 25 unused meals whose effects tie into the cut ability to eat them outside of the dining hall. However, the way they are organised and what is actually there is... a little complicated.

• For some reason, Three Houses actually keeps two batches of text for its meals in the same file:
  • Batch 1 (100 entries, of which all but the first 25 are placeholders), located earlier in the menu text file, contains only unused meals.
    • Entries for matching help strings exist, but are all blank.
  • Batch 2 (255 entries, of which all but the first 31 are placeholders), located much later in the menu text file, contains the 13 used meals from the final game, followed by 18 unused ones.
    • This batch does have help strings, albeit only in certain languages (see below).
• The two batches overlap quite neatly:
  • The first 13 entries of batch 1 are the first 13 unused meals, while the first 13 of batch 2 are the used meals.
  • Entries 14-25 of both are identical, suggesting that the two were originally identical before batch 2 overwrote thirteen of the unused meals with the used ones.
  • Entries 26-31 are blank in batch 1, but continue with the last six unused meals in batch 2.

The following list of unused dishes is synthesized from both batches based on that overlap.

How much text is there for each varies drastically by language:

• In all cases, absolutely no Japanese text survives, leaving the slots blank or just putting placeholder text in there.
• For batch 1, every language except Japanese gives every unused one a name string, although in every language except the two Spanish scripts, it's just left in English.
• For batch 2:
  • Their name strings survive in full only in the US English, Canadian French, Latin American Spanish, and Italian translations; Korean, Simplified Chinese and Traditional Chinese have only the first twelve of them, blanking the subsequent slots like Japanese.
  • Their description strings survive in full only in the Latin American Spanish script. Again, Korean and the two Chinese scripts only cover the first twelve meals, blanking the rest.

All but four of the dishes (Albinea grill, fish & fowl pie, magical herb salad, whole roast grouse) come in two variants: a regular one, and a + variant that has been "cooked to perfection" and describes having a stronger effect. Two of the dishes (grilled chicken & herbs, roast duck) also have a third variant which, although they have the same name as the regular one, describes having a weaker effect.

Name (EN)	Description text (ES-LA)	Notes
Grilled Duck	(N/A)	Batch 1 only; batch 2 has the king of beasts steak in this slot.

Pike Casserole +	Lucio de Amid[sic] asado a la perfección. Otorga Vel + 10 en la siguiente batalla. (Amid pike roasted to perfection. Grants Spd +10 in the next battle.)

The perfect version of the fried queen koi. Between the text for the meal and the matching recipe for the regular version, it seems that the catchable queen loach (クイーンローチ) was originally to be called "queen koi" (女王ゴイ).
Sculpin Gratin +	Charrasco gratinado a la perfección. Otorga Mov + 4 en la siguiente batalla. (Bullhead gratin cooked to perfection. Grants Mov +4 in the next battle.)	The perfect version of the sculpin gratin. "Sculpin" is an early translated name for what the final localized script calls bullhead.
Grilled Wolverine & Herbs +	Glotón de Ogma[sic] asado a la perfección. Otorga Car + 10 en la siguiente batalla. (Ogma wolverine roasted to perfection. Grants Cha +10 in the next battle.)

Grilled Chicken & Herbs	Pollo enharinado y cocinado a la brasa con hierbas. Restaura 10 PV. (Floured chicken cooked on a grill with herbs. Restores 10 HP.)	Batch 2 only. A weaker version of the above grilled chicken & herbs listing.
Roast Duck	Se sirve con salsa de bayas. Restaura 20 PV. (It is served with berry sauce. Restores 20 HP.)	Batch 2 only. A weaker version of the above roast duck listing.
Fish & Fowl Pie	Lleva frutas de Noah[sic], urogallo y trucha blanca. Restaura 50 PV. (Has Noah fruit, grouse and white trout. Restores 50 HP.)	"Noah" is an early translated rendering of the Noa fruit's name (and by extension its namesake, Saint Noa). Batch 2 only.

Battalions

Some manner of altering the constitution and abilities of battalions was evidently intended at some point, although this is another one where the few surviving strings don't shed much light on what it would have entailed.

Online Statistics

Near the used strings for online statistics, there's a second batch of more specific variants which break down demographics for the four individual story routes, rather than the general ones used in the final game. The only statistic with no such variants is, unsurprisingly, the certification success one, since its subject is rather route-agnostic.

Combined/Composite Classes

A handful of unused text strings, plus assets for an unused "combined seal" item, allude to an additional category of class variously referred to as "combined classes" and "composite jobs". Unfortunately, the mere fact of their existence is all that we know; what exactly they could have entailed is a total mystery.

Alternate Command List

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Does any functionality for the unused commands (or their equivalents in the final list) survive in the final game?

There is an unused duplicate of the list of commands a unit can carry out after moving, which uses earlier translations for some entries and even has a few unused command names left over.

Text (JP)	Text (EN)	Notes
攻撃	Attack	--
戦技	Arts	Translated as "Combat Arts" in the final game. This early translation also appeared in prerelease footage from the Nintendo Direct 2019 trailer (despite the "Combat Arts" translation having been used in the E3 2018 trailer previously).
踊る	Dance	--
回復	White Magic	Translated as "Assist" in the final game.
装備	Equip	This command is also present (though unused) in the final list, and appeared in prerelease footage from the E3 2018 trailer. In the final game, equipping items is handled through the Items command instead.
持ち物	Possessions	Translated as "Items" in the final game.
物交換	Trade	--
輸送隊	Convoy
会話	Talk
宝箱	Chest
扉	Door
待機	Wait
降りる	Dismount
乗る	Mount
制圧	Seize
兵器	Arms
布陣	Formation	This command is also present (though unused) in the final list, and appeared in prerelease footage from the E3 2018 trailer (with the background graphic used for commands that end the user's turn).
連携攻撃	Linked Attack	Dummied out in the final list. In the final game, Linked Attacks are a mechanic that automatically boosts affected attacks rather than a standalone attack type.
Fアタック	F Attack	Dummied out in the final list. What "F" might have stood for is unknown.
計略	Gambit	--
橋降下	Lower Bridge	Translated as "Bridge" in the final game.
解除	Disable	Translated as "Lever" in the final game.
開ける	Open	--
応援	Rally
盗む	Steal
転移	Teleport	Translated as "Warp" in the final game.
ソティスの加護	Sothis's Protection	Translated as "Sothis Shield" in the final game. This is the only used command that is also named differently in the Japanese script (it's 神祖の加護 in the final list).

Options Menu

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Does any functionality for these options survive in the final game?

These sets of strings seem to describe two unused entries for the in-game options menu.

Name (JP)	Name (EN)	Option Description 1 (JP)	Option Description 1 (EN)	Option Description 2 (JP)	Option Description 2 (EN)
陣形アニメ	Formation Animations	陣形アニメを表示しません	Do not show formation animations.	陣形アニメを表示します	Show formation animations.
スピーカーモード	Speaker Mode	本体スピーカーに合わせた音声出力設定にします	Optimize sound output for system speakers.	本体スピーカーに合わせた音声出力設定にしません	Do not optimize sound output for system speakers.

Victory and Defeat Conditions

One string in the list used for victory conditions goes unused in the final game. It was likely meant for Salvation at the Chapel, as that map has unused event scripting to set Jeralt's AI to move towards the space (13, 3) and to end the map successfully when he gets there.

Text (JP)	Text (EN)
敵の全滅 またはジェラルトが目標地点に到達	Rout the enemy, or Jeralt reaches the target destination.

The list of defeat conditions has many more unused entries, often identifiable by a quirk of the localization—in used entries, "(character)の敗走" is consistently translated as "(character) falls in battle", but the unused ones translate it as "(character) is defeated" instead.

Text (JP)	Text (EN)	Notes
味方の全滅またはレアの敗走	All of your units are defeated, or Rhea is defeated.	Presumably meant for the non-Crimson Flower version of The Battle of Garreg Mach when played on Casual Mode. In the final game, the defeat condition used is instead "All of your units fall in battle, Rhea falls in battle, or the defended location is captured."
(Byleth)、エーデルガルト、メルセデス、 カスパルいずれかの敗走	(Byleth), Edelgard, Mercedes, or Caspar is defeated.	Presumably meant for Mercedes's and Caspar's paralogue when played during Crimson Flower and on Classic Mode. In the final game, this battle is not accessible on that route.
エーデルガルトの敗走	Edelgard is defeated.	Possibly meant for Edelgard's paralogue when played on Casual Mode, given its position in the list of strings. In the final game, the defeat condition used is instead "Edelgard falls in battle, or the defended location is captured."
(Byleth)、アネット、ギルベルトいずれかの敗走	(Byleth), Annette, or Gilbert is defeated.	Presumably meant for Annette's and Gilbert's paralogue when played during Silver Snow, Crimson Flower, or Verdant Wind, respectively, and on Classic Mode. In the final game, this battle is not accessible on those routes because Gilbert cannot be recruited.
(Byleth)、エーデルガルト、アネット、ギルベルトいずれかの敗走	(Byleth), Edelgard, Annette, or Gilbert is defeated.
(Byleth)、クロード、アネット、ギルベルトいずれかの敗走	(Byleth), Claude, Annette, or Gilbert is defeated.
(Byleth)、イングリット、ドロテア いずれかの敗走	(Byleth), Ingrid, or Dorothea is defeated.	Posssibly meant for Ingrid's and Dorothea's paralogue when played during Silver Snow and on Classic Mode. In the final game, this battle is not accessible on that route because it is only available before the timeskip.
(Byleth)、エーデルガルト、リシテア、 フェルディナントいずれかの敗走	(Byleth), Edelgard, Lysithea, or Ferdinand is defeated.	Presumably meant for Ferdinand's and Lysithea's paralogue when played during Crimson Flower and on Classic Mode. In the final game, this battle is not accessible on that route.
(Byleth)、エーデルガルト、ヒルダ、ツィリル いずれかの敗走または友軍全滅または防衛地点の陥落	(Byleth), Edelgard, Hilda, or Cyril is defeated, ally units are defeated, or the defended location is captured.	Presumably meant for Hilda's and Cyril's paralogue when played during Crimson Flower (or during the Black Eagles version of White Clouds before the route split) and on Classic Mode. In the final game, this battle is not accessible on those routes because Hilda cannot be recruited.
(Byleth)または友軍の全滅	(Byleth) or ally units are defeated.	In the final game, only specific named units are ever a defeat condition when falling in battle as an ally unit, though some maps give additional rewards at the end of the battle for keeping generic allies alive.
(Byleth)、エーデルガルトいずれかの敗走 または友軍の全滅	(Byleth), Edelgard, or ally units are defeated.
(Byleth)、ディミトリいずれかの敗走 または友軍の全滅	(Byleth), Dimitri, or ally units are defeated.
(Byleth)、クロードいずれかの敗走 または友軍の全滅	(Byleth), Claude, or ally units are defeated.
ディミトリの敗走または友軍の全滅	Dimitri or ally units are defeated.
エーデルガルトの敗走または友軍の全滅	Edelgard or ally units are defeated.
クロードの敗走または友軍の全滅	Claude or ally units are defeated.
(Byleth)、エーデルガルト、 リンハルト、レオニーいずれかの敗走	(Byleth), Edelgard, Linhardt, or Leonie is defeated.	Presumably meant for Linhardt and Leonie's paralogue when played during Crimson Flower and on Classic Mode. In the final game, Edelgard cannot be deployed in this battle.
イエリッツァの敗走	Jeritza falls in battle.	Presumably meant for Anna and Jeritza's paralogue. In the final game, Anna falling in battle is always also a defeat condition for this battle.
(Byleth)またはイエリッツァの敗走	(Byleth) or Jeritza falls in battle.

Unit Information

The list of names and help-text descriptions for the various conditions seen on in-battle unit status screens has quite a few unused entries.

Name (JP)	Name (EN)	Description text (JP)	Description text (EN)
猛撃	Staggering Blow	魔物が行う特殊な攻撃。 発動前に予備動作をとる。	A monster's fierce attack, which requires some posturing before unleashing their blows.
弱点：格闘	Weakness: Hand-to-Hand	格闘による攻撃が「有効」になる。	Hand-to-hand attacks are especially effective.
弱点：白魔法	Weakness: White Magic	白魔法による攻撃が「有効」になる。	Attacks using white magic will become effective.
弱点：黒魔法	Weakness: Black Magic	黒魔法による攻撃が「有効」になる。	Attacks using black magic will become effective.
弱点：闇魔法	Weakness: Dark Magic	闇魔法による攻撃が「有効」になる。	Attacks using dark magic will become effective.
障壁スキル発動中	Barrier Ability Active	障壁が残っていることにより 障壁スキルが発動している状態。	The barrier ability is still active because the boss still has an active barrier.
猛撃カウント	Staggering Blow Count	戦闘を行うとカウントが減り、 「！」になると猛撃準備に入る。	Character will enter Fierce Attack preparation when fighting boss and the count goes down to "!"
追撃ガード	Follow-up Guard	戦闘時、敵の追撃をガードし、 ダメージを受けない。	Blocks the enemy's follow-up attacks and prevents damage when fighting.

Status Conditions

These name strings for unused status conditions have no corresponding description strings remaining, so what their effects might have been is unknown. That said, it can be assumed that "Cause and Effect" would've been granted by a gambit, as it's located among other conditions of that type (Sacred Shield, Retribution, etc.) and its Japanese name is worded similarly to theirs.

Text (JP)	Text (EN)
因果の備え	Cause and Effect
冷静沈着	Calm

Popup and Objective Notifications

The strings for the system message popups that appear during monastery explorations and battles, as well as those for the current-objective sidebar text seen during explorations (aside from the ones tied to active quests), are stored in sets on a per-map basis, and some of these lists contain leftover entries that go unused in the final game.

...But does it make sense? The translations on this page need to be proofread. If you are fluent enough in this language, please make any corrections necessary!

Exploration	Text (JP)	Text (EN)	Notes
Three Houses (Chapter 1, before choosing a house)	大修道院内を回って、各所にいる人たちに 話しかけてみましょう。	Try walking around the monastery and talking to the people there.	In the final game, progressing the story here only requires talking to the three house leaders and then returning to Rhea.
	全員と話すと、物語が進みます。	Once you've spoken to everyone, the story will progress.
	ハンネマンの話を聞こう	(I'll talk to Hanneman...)	--
Three Houses (Chapter 1, after choosing a house)	ベルナデッタの部屋 (Bernadetta's Room)	iron_untranslated	--
	掲示板を確認しよう (Check the bulletin board.)	iron_untranslated	Likely meant as current-objective text rather than as a popup, given the phrasing.

Battle	Text (JP)	Text (EN)	Notes
A Skirmish at Dawn (Prologue)	ベレトにカーソルを合わせて 決定し、「移動」を選んでください。	Put the cursor over (Byleth) and confirm, and then select "Move."	All of the messages in this chapter are along the same lines as the text of the tutorials that are used to introduce these mechanics instead in the final game. In the final game, selecting a unit brings up the movement interface right away rather than requiring it to be selected from a menu first.
	盗賊に隣接するようにユニットを 移動させてください。	Command will open[sic] after positioning next to enemy[sic]. Choose "Attack," and attack the thieves.	--
	敵に隣接すると、コマンドが開きます。 「攻撃」を選び、盗賊を攻撃しましょう。	A portion of the terrain will have an effect on the parameters of the unit.
	一部の地形は、ユニットのパラメータに 影響を与えます。	For example, units in the forest will have strengthened Avo or Def.
	有利な地形にユニットを移動させ、 敵の攻撃に備えましょう。	Move your units to advantageous terrain, and prepare yourself against enemy attacks.
	味方の攻撃範囲にいる敵を攻撃すると、 連携攻撃になります。	Attack enemies that are in your allies' attack range, and you will achieve a ;//linked attack[sic].
	連携攻撃は、通常より命中と必殺が 上がります。	Your Hit and Crit will rise above normal when doing a linked attack.	In the final game, linked attacks raise Hit, Avo, and sometimes Mt instead.
	強力な敵を相手にする時には、 連携攻撃を活用しましょう。	Use the linked attack when facing a very powerful enemy.	--
	また、連携攻撃を行ったユニット同士は、 友好度が上がり、仲が良くなります。	The units that conduct a linked attack will improve friendship, and get closer to each other.
	他にも深い森や魔法陣など 様々な地形が存在します。	There are multiple other types of terrain, as well, such as Thicket and Sigil.	"Sigil" is not an existing terrain type in the final game.
	初めて見る地形が出てきたら Xボタンで調べてみてください。	When you see a type of terrain for the first time, press the X Button to learn more about it.	--
	詳細情報にアイテムのアイコンがある敵を倒すと 緑色の文字で表記されたアイテムを落とします。	When you defeat an enemy with an Item icon in their Details, the item listed with green-colored text will drop.
Rivalry of the Houses (Chapter 1)	布陣すると、陣形を組んだ状態に、 散開すると、陣形を解いた状態になります。	If make a Formation[sic], you will create a battle formation. If you Disperse, the formation will be disbanded.	No mechanic like this exists in the final game at all. However, a "Formation" command did appear in the game's initial E3 trailer in 2018, so perhaps this text is left over from that point in development?
	布陣状態では、陣形の種類に応じて ユニットが強化されます。	While in a Formation, units will be strengthened. How so depends on the Formation type.
	敵が布陣状態の場合は、味方も布陣状態に ならないと、撃破は難しくなります。	When the enemy is in Formation, it will be harder to destroy them unless your allies are also in Formation.
	ユニットが散開状態だと、移動力が上がり、 戦技が使えるようになります。	When units are dispersed, their movement is increase[sic], and you can use Combat Arts.
	布陣してユニットの能力を強化するか、 散開して戦技と移動力を優先するか……	So you can choose whether to make a Formation and strengthen your units, or disperse and prioritize movement and Combat Arts.
	どちらが有利かを判断しながら、 臨機応変に切り替えて戦うと良いでしょう。	Switch between the two options on the fly, depending on what you determine to be more effective.
	布陣状態のユニットは、率いる騎士団に 応じた能力も強化されます。	Units in Formation will have their abilities enhanced depending on the Knights in their formation.	"Knights" here is an early translation for Battalions, as seen in the unused tutorial guides.
	また、騎士団ごとにそれぞれ異なる 計略を使えます。	Additionally, each group of Knights has a different gambit that you can employ.
Red Canyon Dominance (Chapter 2)	宝箱の前までユニットを移動させると、 開けることができます。	Move a unit up to the treasure box, and you will be able to open it.	Another mechanic explanation that's given using the built-in tutorial system rather than with this type of message in the final game.
Assault at the Rite of Rebirth (Chapter 4)	特定の床にいるユニットは、 防御系のパラメータが大きく強化されます。	Units in specified areas on the map will receive a boost to their defensive stats.	In the final game, the special terrain types on this map are pointed out in dialogue but not explicitly described like this, probably because the player can just check their effects themselves on the map view at any time.
	この床は、防御が強化されます。	Prt will be boosted on this section of the map.
	この床は、魔防が強化されます。	Res will be boosted on this section of the map.
	この床は、回避が強化されます。	Avo will be boosted on this section of the map.
The Gautier Inheritance (Chapter 5)	魔物は複数のHPゲージを持ち、 強力な「守護」を纏う非常にタフな敵です。 同じ場所を攻撃したり、計略や有利な武器で 攻撃をすると「守護」を破壊できます。	Monsters are extremely tough enemies with powerful Barrier[sic], and they have multiple HP gauges. You can destroy their Barrier by attacking the same spot, or attacking with a strategy or an effective weapon.	An explanation of monsters and their mechanics that covers the same points as the tutorials used for this purpose in the final game, though with more explicit details and from a neutral perspective instead of Sothis's. "Fierce Attack" is an early, more literal translation for the attack type known as Staggering Blow in the finished localization.
	戦闘をして「守護」を破壊すると、魔物は 「アーマースキル」が無効化し、次の戦闘のみ 反撃をしてこない混乱状態になります。 複数人で上手く「守護」を連続で破壊し、 反撃を受けずに倒すことも可能です。	When you destroy their Barrier during combat, the monster's Armor Abilities are nullified, and for the next battle only they will enter a Confused state in which they don't counterattack. It's also possible to use multiple people to repeatedly destroy the Barrier and defeat the enemy without being counterattacked.
	魔物は２ターンに１回、強力は範囲攻撃 「猛撃」を撃とうとしてきます。 魔物は計略で攻撃した部隊を狙うので 計略を使いつつ上手く「猛撃」を避けましょう。	Every other turn, monsters attempt to perform a powerful area attack called a Fierce Attack. Monsters will aim for units that attack with gambits, so dodge Fierce Attacks well as you use gambits.
	「守護」を全て破壊し「アーマーブレイク」と なり、以下の効果が得られます。 ・特殊なアイテムを入手できる ・魔物の「守護」が復活しなくなる ・魔物が次のターン行動不能になる	When all Barriers have been broken, their armor will be broken, allowing you to get the following effects: - Get special items - The monster's Barrier will stop recovering - The monster will be unable to act on the next turn
	削除 (Deleted)	iron_untranslated	--
	追いつめられると「状態変化スキル」が 有効になる魔物がいます。 どんなスキルを持っているかは ユニット詳細で確認できます。	There are monsters that have Status Ailment Skills which are activated when they are cornered. You can check which Skills they have by checking their Unit Details.	An event script to display this text during the battle does still exist in the final game, but goes unused.
The Underground Chamber (Chapter 6)	敗北まで　あと１ターン	Turns left until defeat: 1	In the final game, these warnings appear at the same time as the banner marking the start of Enemy Phase rather than as separate popups.
	敗北まで　あと２ターン	Turns left until defeat: 2
	敗北まで　あと３ターン	Turns left until defeat: 3
	敗北まで　あと４ターン	Turns left until defeat: 4
	敗北まで　あと５ターン	Turns left until defeat: 5
Salvation at the Chapel (Chapter 9)	モンスターは計略を当てた部隊を 狙うように行動します。 「猛撃」の向きもコントロールできるので 計略を活用して生徒たちを助けましょう。 (Monsters will aim at units that attack them with gambits. You can also control the direction of their Staggering Blow, so use gambits to help the students.)	iron_untranslated	Some advice on how to protect the NPC units in this chapter, perhaps cut because the player has already been introduced to monster mechanics well before this point.
Conflict in the Holy Tomb (Chapter 11)	紋章石を奪った敵を撃破せず戦闘に勝利すると、 敵の撤退に紛れて紋章石を奪われてしまいます。 注意しましょう。	If you win the battle without defeating an enemy that has stolen a Crest Stone, that Crest Stone will be lost. Plan carefully.	--
Taking Fort Merceus (Silver Snow Chapter 17/Verdant Wind Chapter 18)	死神騎士が撤退に成功したため、勝利条件が変更されました。 (Because the Death Knight successfully retreated, the victory condition has changed.)	iron_untranslated	Possibly removed for being redundant, as the dialogue lines and new-victory-condition banner that appear in this situation are fairly self-explanatory.

True Chivalry (Paralogue – Felix)	村人救出に失敗しました…… (You failed to rescue the villagers...)	iron_untranslated	--
The Forgotten (Paralogue – Sylvain)	討伐数に応じて報酬がもらえます。 (You will be rewarded based on how many you defeat.)	iron_untranslated	Nearly identical to the second line of a used message displayed at the start of the battle.
Rumored Nuptials (Paralogue – Ingrid/Dorothea)	イングリットはベレトに従って 移動します。 敗走しないよう注意しましょう。	Ingrid will move along with Byleth. Be careful not to get defeated.	An event script to display this text during the battle does still exist in the final game, but goes unused. Likely refers to the unused movement scripting for the unrecruited version of Ingrid on this map, as its conditions indicate it would've appeared at the start of the battle if that version of her is present.
Foreign Land and Sky (Paralogue – Petra/Bernadetta)	援軍を呼ぶため、ペトラが一時離脱しました。	Petra temporarily left to call for reinforcements.	Scripted to appear in the unused alternate version of Petra bringing reinforcements from the western stronghold, for moving the unused unrecruited version of Petra onto it.
Death Toll (Paralogue – Raphael/Ignatz)	商人をあまり助けることができませんでした。 (You weren't able to help the merchants very much.)	iron_untranslated	Various other missions that have rescuing NPCs as a secondary goal use a set of messages along these lines to report on your level of success at the end of the battle, but this one leaves them all unused for unknown reasons.
	商人を何人か助けることができました。 (You helped some of the merchants.)	iron_untranslated
	商人を全員助けることができました。 (You helped all of the merchants.)	iron_untranslated
Dividing the World (Paralogue – Hilda/Cyril)	ゴネリル兵を助けることが できませんでした…… (You failed to help the Goneril soldiers...)	iron_untranslated	--
An Ocean View (Paralogue – Seteth/Flayn)	(blank)	Ensure that Seteth and Flayn are not defeated!	--
A Skirmish in Abyss (Cindered Shadows Chapter 1)	布陣すると、陣形を組んだ状態に、 散開すると、陣形を解いた状態になります。 (If you make a Formation, you will create a battle formation. If you Disperse, the formation will be disbanded.)	tTemporarymessage	Identical to the first unused line from Chapter 1 of the main story.
Ambush in the Arena (Cindered Shadows Chapter 2)	布陣すると、陣形を組んだ状態に、 散開すると、陣形を解いた状態になります。 (If you make a Formation, you will create a battle formation. If you Disperse, the formation will be disbanded.)	tTemporarymessage
Search for the Chalice (Cindered Shadows Chapter 3)	魔法の鍵を失ったため、 ゴーレムを止められませんでした	The mechanism wasn't stopped because the magical key was lost...	The "magical key" presumably refers to the Spellbreak Key item used in this chapter, which cannot be lost in the final game.
A Harrowing Escape (Cindered Shadows Chapter 4)	扉が閉まるまであと５ターン。	5 turns left until the gates close.	Similar messages are used in the final game, but only at the 10- and 4-turn marks.
	扉が閉まるまであと３ターン。	3 turns left until the gates close.
	扉が閉まるまであと２ターン。	2 turns left until the gates close.
	扉が閉まるまであと１ターン。	1 turn left until the gates close.
Besieged in the Chapel Ruins (Cindered Shadows Chapter 5)	布陣すると、陣形を組んだ状態に、 散開すると、陣形を解いた状態になります。 (If you make a Formation, you will create a battle formation. If you Disperse, the formation will be disbanded.)	tTemporarymessage	Identical to the first unused line in Chapter 1 of the main story.
A Beast in the Cathedral (Cindered Shadows Chapter 7)	布陣すると、陣形を組んだ状態に、 散開すると、陣形を解いた状態になります。 (If you make a Formation, you will create a battle formation. If you Disperse, the formation will be disbanded.)	tTemporarymessage

Miscellaneous

This batch was found in the listings for battle missions. They seem to describe debugging options, including debug maps. There are two copies of these strings, identical to each other in Japanese; the first English instance (at the end of the list of mission names) is left untranslated, while the second is translated.

String (JP)	String (EN #1)	String (EN #2)	Notes
プロトタイプ	iron_untranslated	Prototype	--
αシナリオ	iron_untranslated	α scenario	--
チュートリアル	iron_untranslated	Tutorial	--
５章：竜の祭壇へ	iron_untranslated	Chapter 5: Dragon's Table	A chapter title left over from Fire Emblem Warriors, also developed by Koei Tecmo.

ＤＳ静止画撮影用	iron_untranslated	For screenshots	--
邪竜テスト	iron_untranslated	Fell Dragon test	Another Fire Emblem Warriors leftover, where it would have been a test for Velezark. In Japanese, Velezark uses the same epithet as Grima, 邪竜 (evil dragon), but the two games translated them differently; Grima was called the "Fell Dragon", while Velezark became the "Chaos Dragon". The Three Houses localizers seem to have confused the latter for the former, not that it matters much.
キャラチェンジテスト	iron_untranslated	Character change test	--
部隊戦闘テスト	iron_untranslated	Unit battle test	--
北裏テスト用	iron_untranslated	For Kitaura's tests	Nobody by this name is credited for Three Houses; it may be a leftover from Fire Emblem Warriors, where Ryuta Kitaura is credited under "game design".
襟川テスト用	iron_untranslated	For Erikawa's tests	Nobody by this name is credited for Three Houses; it may be a leftover from Fire Emblem Warriors, where Tetsuya Erikawa is credited under "game design".

The unused Infernal difficulty has its own name and description strings, stored next to those of the used difficulty settings.

Text (JP)	Text (EN)
インファナル	Infernal
極めている方に	For those seeking the ultimate challenge.

Most of the strings in the list of song titles are either used tracks or blanks, but one unused title is still present (though no corresponding sound file exists).

...But does it make sense? The translations on this page need to be proofread. If you are fluent enough in this language, please make any corrections necessary!

Text (JP)	Text (EN)
灼熱の極楽 (Burning Paradise)	Burning Up

Possibly related to the game mechanic of bows incurring penalties to hit rate when attacking from a range of 3 or more spaces away from the target?

Text (JP)	Text (EN)
弓射程３　命中(n)	Bow Range: 3, Hit: (n)
弓射程４　命中(n)	Bow Range: 4, Hit: (n)
弓射程５以上　命中(n)	Bow Range: 5 or more, Hit: (n)

These odd strings might've been meant for examinable locations in the monastery; there are two entries for each one's description text, which are identical in Japanese but translated differently in English. The first version of the descriptions is located next to the unused lost item descriptions, while the names and later descriptions are located with those of the collectable monastery texts.

Name (JP)	Name (EN)	Description text (JP)	Description text (EN)	Description text (EN #2)
祭壇	Altar	神を祀る祭壇がある。 セイロス教の神は、翼を持った女性や 星を象徴とする女神として描かれ、 竜を従えているという。	An intricately carved altar dedicated to the goddess. In an engraving, the goddess is depicted as a young woman with wings, surrounded by stars, and flanked on both sides by dragons.	An intricately carved altar honoring the goddess. An engraving depicts her as an elegantly winged young woman surrounded by stars and accompanied by dragons.
士官学校	Officers Academy	士官学校の建物が見える。 士官学校は、 エーデルガルトを級長とする黒鷲の学級、 ディミトリを級長とする青獅子の学級、 クロードを級長とする金鹿の学級 の３学級がある。	You see a the[sic] Officer's Academy, a cluster of buildings. The Officer's Academy has three houses: the Black Eagle house, led by Edelgard, the Blue Lion house, led by Dimitri, and the Golden Deer House, led by Claude.	The Officers Academy is within sight. It is comprised of three distinct houses: the Black Eagles, led by Edelgard, the Blue Lions, led by Dimitri, and the Golden Deer, led by Claude.

"Assistants" here is an early translation for Adjutants. What "test battles"/"お試し出撃" might've referred to is unknown.

Text (JP)	Text (EN)
お試し出撃のため副官を設定できません	Assistants cannot be assigned in test battles.

In the final game, talking to the NPCs for cooking, sharing a meal, or choir practice will bring up the relevant menu automatically rather than giving a yes/no prompt like this first.

Text (JP)	Text (EN)
料理を作りますか？	Would you like to cook a meal?
合唱練習しますか？	Do you want to do some choir practice?
誰かをご飯に誘いますか？	Invite people to share a meal?
合唱練習しますか？	Do you want to do choral practice?

The location and wording of these strings implies that they're referring to choir practice, which doesn't affect motivation in the final game (though the menu for selecting units to participate in it still displays their current motivation, perhaps as a relic from this stage of development), and can't be performed with fewer than three characters.

Text (JP)	Text (EN)
練習に参加した仲間たちの やる気がアップしました	Motivation improved for the allies who practiced.
(name)が信仰経験値を獲得	(name) gained faith experience.
(name)が信仰経験値をいつもより獲得！	(name) gained a significant amount of faith experience!
２人が信仰経験値を獲得	The two gained faith experience.
２人が信仰経験値をいつもより獲得！	The two gained a significant amount of faith experience!

Somewhat less interestingly, there are also various alternate phrasings of description texts for monastery activities, some of which were blanked out in the Japanese script. The entries about identifying the author of a letter might've been meant for the Advice Box.

Text (JP)	Text (EN)
(blank)	Select bait
(blank)	Select seed
(blank)	Select two people for choral practice.
(blank)	Select one more person.
(blank)	Try to deduce who wrote the post
(blank)	Select tournament entrant.
合唱練習する相手を２人選択してください	Select two people to join in choir practice.
もう１人選択してください	Select one more person.
練習に参加した仲間たちとの 親睦が深まりました	Your friendship with the practice participants deepened.
ご飯を一緒に食べた仲間の やる気がアップしました	Motivation went up for the members who ate together.
投書の主を推理してください	Guess who wrote the letter.

In the final game, teatime is only available as a choice when talking to a character at the monastery or on their birthday.

Text (JP)	Text (EN)
(name)とすれ違いました お茶会に誘いますか？	You ran into (name). Invite them to tea?

You can increase support points on a character's birthday with a tea party or gifted flowers, but the birthday itself doesn't give any motivation or support points in the final game.

Text (JP)	Text (EN)
(name1)の誕生日です(name1)のやる気がアップしました(name1)と(name2)の支援値が上昇しました	It's (name1)'s birthday! (name1)'s motivation increased. (name1) and (name2)'s support points increased.
(name1)の誕生日です(name1)と(name2)の支援値が上昇しました	It's (name1)'s birthday! (name1) and (name2)'s support points increased.

In the final game, none of the monastery activities that characters can have specific proficiencies in (cooking together, choir practice, being instructed in a particular subject, and completing particular group tasks) can increase motivation.

Text (JP)	Text (EN)
(name1)が得意な(name2)らのやる気がアップしました！	Motivation for (name2) & co. increased because they excel at (name1)!

These strings are located next to "Offer some tea", so they might've been alternate options to it.

Text (JP)	Text (EN)
お茶菓子を勧める	Offer a snack
面白い話をする	Make conversation

In the final game, setting a unit as an online traveler does not exclude them from any other areas of gameplay while they're traveling.

Text (JP)	Text (EN)
留学中は選択できません	Unavailable due to studying abroad.

Apparently, it was once possible to fail at the gardening activity...

Text (JP)	Text (EN)
作物が枯れて収穫できませんでした	The crops withered and couldn't be harvested.

No feature like this exists in the final game.

Text (JP)	Text (EN)
引き換えコード	Redeem Code
引き換えコードを入力して特典を獲得できます	Enter a code to receive special perks.

A set of unused exam requirement descriptions, two of which specify conditions that don't exist in the final game.

Text (JP)	Text (EN)
Lv.1以上で受験できます	This exam can be taken at Lv. 1 or higher.
Lv.30以上で受験できます	This exam can be taken at Lv. 30 or higher.
指導Lv.B以上で受験できるようになります	This exam can be taken at Professor Level B or higher.

Even a unit who hasn't taken any certification exams will still be certified in the class they start out in, so this scenario never applies.

Text (JP)	Text (EN)
１つも資格を所持していません	This unit is not certified in any classes.

In the final game, if a battle ends without anyone having qualified for MVP status, Byleth will become the MVP by default.

Text (JP)	Text (EN)
ＭＶＰはいませんでした	There was no MVP[sic]

An unused string presumably meant to be shown after completing the DLC quest Roster Retrieval, along with a copy of the used lines for this situation (the actual used lines are stored elsewhere). The latter two lines are translated slightly differently in the English script compared to their used equivalents.

Text (JP)	Text (EN)
裏名簿を入手しました	You have acquired the secret roster.
裏名簿を入手したことで、落とし物に 手がかりが表示されるようになりました	Now that you have the secret roster, hints will be displayed for lost items.
キャラクターに話しかけ、 コマンドが出ている時にＸボタンを押すと、 名簿を確認できるようになりました	When you speak to a character, you can check the secret roster by pressing the X Button when the command is displayed.
お茶会で選択を間違えそうになった時に、 一度だけ直感が働くようになりました	You can now use your intuition once during a tea party.
