Ryuki's dream in the opening sequence.

Ryuki is dreaming, but it purposely doesn't look like a dream.

All of the scenery feels realistic (just like it is in the investigation part)

Line (JP) Line (EN) Comment Translation
第2サイクロ事件…複数の人間が\n左目をくり抜かれて殺された、あの事件のことです Host: The New Cyclops Serial Killings... The incident in which many victims got their eye gouged out and murdered... //この世界線は前作のGrand Finaleと繋がっているので、第2サイクロ事件で殺されたのは硝子と沖浦の2人だけ。 Since this world line is connected to the previous game's Grand Finale, the only two people killed in the New Cyclops Serial Killings were Shoko and Renju.
Only b2 is not split. It's a metaphor for the number of victims in the main story. (During cutscene at the end of Ryuki's dream. "b2" refers to the blue figure sitting to Boss's right.)
Supplement: Behind the scenes

This file pretends to be Ryuki's dream in the past (6 years ago), but is actually Ryuki's dream in the present. Ryuki has this dream after drinking and getting drunk at Brahman. So, the blue people and Boss being halved is not a "precognitive dream," but rather caused by past trauma.


Mizuki's first appearance at the Stadium.

//・正式名称『Evolver-MC』//MCは『Mizuki Custom』の略。
There is a gun at Mizuki's left armpit (inside the uniform jacket). Usually unseen.

The gun is like Date's Evolver. The official name is "Evolver-MC," MC short for "Mizuki Custom." It transforms like Date's Evolver. It can also be loaded with various bullets such as fire rounds and explosive rounds in the same way.

Masked Woman.

Carries a rifle. No scope (She has Marco, so the scope is unnecessary)


The body appearing at Studio Dvaita in the past.

//・看板には『Fray to Free!』という文言と『QRコード』が記されている。//◎inc確認。別案:『Be Frayed to Be Free』『Be Frayed, Not Afraid』
"Fray to Free!" and a QR code are on the signboard. Alternatives: "Be Frayed to Be Free," "Be Frayed, Not Afraid"

Ryuki's investigation at the studio.

元気2倍、半パンマン!! Ryuki: Two times as energetic, Hanpanman!* //ちなみに正規の時系列順に倍々になっていきます By the way, this doubles in normal chronological order.

*Japanese equivalent of Ryuki's "Half Might" reference. Every time this line comes up, the number is a different multiple of 2. A ticket number on every Hanpanman line suggests it was changed from something else.

大丈夫だよ…\n私、これよりももっと悲惨な死体、見たことあるし… Mizuki: I'm fine... I've seen worse. //『サンポケで吊り上げられた沖浦の死体のこと』ではない。それは別の世界線でのこと。この世界線でみずきが見たのは『犀人のアジトに転がっていた沖浦』と『頭が吹っ飛んだ犀人』 Not Renju's body suspended at Sunfish Pocket. That was in another world line. In this world line, what Mizuki saw was Renju's body lying in Saito's hideout, and Saito's head blown off.

手足が生えた44歳の鯖のことだ Aiba: She's a 44-year-old mackerel that grew limbs.* //前作では38歳。6年後なので44歳。 38 years old in the previous game. 6 years later, she's 44.

*Direct translation. In AI1's Japanese text, the "Sabako" Aiba jokes about coming from the Psync Room TV is a 38-year old mackerel with limbs.


This appears to be a placeholder file where Ryuki's Somnium would be. The actual code is stored in M0_somnium, but all placeholder Somnium files have detailed background information.

*Psyncer: Mizuki
  • Subject: Ryuki
  • Location: Naix Underground Cathedral (West)

  • Before the Psync

Ryuki was in charge of the HB case 6 years ago. He might know something... That's Mizuki thought, so she went to ask him, but he was drunk and not able to hold a proper conversation. So, she decided to Psync...

  • In his heart

Ryuki is in agony like he's being chopped to pieces over losing Date in the explosion 6 years ago. He thinks, "it's my fault Date was killed." In fact, it is his fault for getting everyone involved in the explosion, but but will not be revealed yet. Ryuki has always been suffering mentally, but that's why his condition has gotten worse. His mental state got even worse and he became an alcoholic.

  • Supplement:

Ryuki was already suffering even more Side Ryuki (prior to 6 years ago) because of the aftereffects of seeing the scene of his brother's accident.
Branch: Yes
Divides into Side Ryuki route and Side Mizuki route.

  • Supplement:

Please do not try to enter Side Mizuki route without clearing both endings of Side Ryuki. There is no flag. "The culprit's last name is Dahlia" is heard in Side Ryuki chapter 4 R2 end. "The culprit's first name is Boat" is heard in Side Ryuki chapter 5 R1 end. If you don't hear these, you can't enter Side Mizuki. I think a "What is the culprit's name" password input is good. If you can enter "Dahlia Boat," you'll go to Side Mizuki route.

  • Supplement:

This means this will be the 8th Somnium for players. They'll play this stage a secong time. So... please set the difficulty of "Side Ryuki route" to Super Very Easy, and "Side Mizuki route" to moderately hard.

  • Final facts revealed: Side Ryuki

A blue person appears. #Uchi (12/26): At first, I supposed the blue person would be Tearer or Tokiko, but because of the Somnium's connection, the blue person became Date.

  • Final facts revealed: Side Mizuki

"Dahlia Boat" itself is the last fact to be revealed. Mizuki (Aiba?) should not know "Dahlia Boat," but somehow she does. (Aiba was at the scene of the explosion, but after that all her memories were erased.) Even though Mizuki (and Aiba) don't know, the player knows. This implies the player's position in relation to this game. (Tokiko's ultimate goal is to contact the player.)

R1_Somnium (New Investigation)

Fade in from white. A blue eyeball drops and rolls on the desk. (Eyeball that looks like a blue person’s) (Mizuki’s lost left eye)
#Uchi: Mizuki was in the cathedral at the time, so she knows about the cathedral.

#Uchi: Aiba has lost her memories, but she also knows there was an explosion at the cathedral.

Suddenly, when you look at the ceiling, the rubble has all become red left hands. (Palms facing down) (Uru's left hand)

(Note: The hands in game appear green.)

With a deep sense of regret, Ryuki once put the muzzle of a gun to his temple in the past. (In the end, he didn’t shoot)
Fade in from white. The blue lower half of a body drops at Ryuki’s side. (Left half looks like a blue person’s) (Kizuna’s lower half that has stopped moving}
Line (JP) Line (EN) Comment Translation
僕は!! あいつを許さない!!\n絶対にあいつを!! あいつを!! Ryuki: No, no, no, no! No forgiveness, no mercy, never! //あいつ=鉄仮面の男のこと Referring to the man in the iron mask.
あれ…この警察のIDって… Mizuki: Hey, this police ID is... //見覚えがある。伊達のものだから She recognizes it because it belongs to Date.
The rubble from the ceiling falls, burying Ryuki. The rubble piles up on Ryuki, showing only his head and right arm and shoulder. Ryuki imagined how painful it would be if he were in Date’s position, and dreams of it often…
#Uchi: By the way… In the plot, it says the blue person who reaches out here was Tearer. But, I’ll match it with the investigation part with the above development. The plot also says “the blue person says some memorable words,” but please forget this. We’ll figure something out.

Mizuki: Tama was Ryuki's anchor... She kept him tethered to the real world.

Aiba: Right…

//ちょっと伊達のことを思い出す感じで Feels like she remembers Date for a moment


Aiba: Awfully strange advice...

Mizuki: Yeah...

//伊達のそういうとこ好きだけど認めたくない強がり含めての『ふーん…』 Mizuki likes that side of Date but doesn’t want to acknowledge it so she bluffs and says “Yeah…”
かぼちゃ美味しいな、龍木! Aiba: Pumpkins sure are yummy, huh Ryuki? //#打:内側から食べてるって意味ですかね…? // *Uchi: Does she mean she’s eating it from inside?
Time Bomb @ M

This was wrapped around Kizuna in Side Ryuki Chapter 5. // #Uchi: Kizuna was only restrained to a chair, not with a bomb wrapped around her body. The bomb was behind Kizuna. We’ll interpret it as that bomb and move forward.

Ryuki meeting with Boss and Date on 2/11 (in the past).


“6 years ago” cannot be written on the title screen, since Side Ryuki Chapters 2 and 4 are not “6 years ago.”

Line (JP) Line (EN) Comment Translation


Ryuki: You went to a host club in Kabukicho after the investigation, didn't you?

Boss: Who would do such a thing...?

//誰も言ってない。ピュータが言ったのは『みずき編(現在時間)』でのこと。 No one said it.* Pewter said it in Side Mizuki (the present time)

*Direct translation of Boss’s line would be “Who said that?”

Iris: Don't you know today is February 11? National Foundation Day?

Ryuki: Oh, right...

After this, Shoma goes out. Komeji comes home and takes his place, and Amame comes to the home too. There, they talk about Jin’s left half (in the suitcase) hidden under the floor. Amame takes it and goes to Brahman.

// Aの左側とBの右側を融合させたらどうなるのか?について知りたがっている。


*Location: Horadori Institute of Genetics lab

  • In Chikara’s heart 1

Chikara is shaken because his child (Jin Furue) was killed. He’s also terribly sad. He also knows the culprit. It’s Uru, who was confined in the basement. But his lips are sealed no matter what.

  • In Chikara’s heart 2

Chikara has an insane level of interest in immortality.

  • In Chikara’s heart 3

Chikara is a crazy mad scientist. He wants to know what would happen if you cut two bodies, A and B, into left and right halves, then fused the right half of A with the left half B, or the left half of A with the right half of B. He was attempting to carry out an experiment for that purpose.

  • Branch: No

  • Final facts revealed

A person wearing a Naix uniform (with the Nonuple-X with “Naixatloz” written on it) enters. The Naix member heads for the PC and makes a video. Approach the video → it turns out to be Bats490. Or, the opposite sequence, Bats490 → Naix follower → Nonuple-X mark and Naixatloz, is also fine.

R1_Somnium (Nefarious Institute)

// この状態を法螺鳥は『エピジェネティックエクスタシー状態』と呼ぶ
// (『エクスタシー!!』と叫んだりする)
// 『このシミュレーション世界はなんでもできるし、なにをやっても許される素晴らしい世界だ!』
Because of the experiment’s success, and Chikara’s inspiration, his brain floods with pleasure-inducing chemicals. Chikara calls this state “Epigenetic Ectasy.” (He shouts something like “Ectasy!”) “This simulation is a wonderful world where you’re allowed to to anything!”

Ryuki visiting Naix to meet Tokiko. The dialogue below refers to the nil number input.

// * 突如プログラムが狂い出して、ゲームが『バグモード』になる。

If the answer is correct:

The program suddenly starts malfunctioning and the game enters “bug mode.” The events after that are not related to the main story, so I’ll write them after everything. Please refer to the plot for details.

Ryuki visiting the shrine (in the present) before viewing Chikara's body in VR.

Placeholder file for Tokiko's Somnium.







//『ニルヴァーナ構想(Nirvana Initiative)』
//その計画の名は『ニルヴァーナ構想(Nirvana Initiative)』という。
  • In her heart 1

Tokiko is a believer in simulation theory. Her ultimate goal is to cause glitches in this world and achieve Moksha. Tokiko is aware of the player's existence. She wants to confuse and disturb players and cause the world's program to malfunction.

  • In her heart 2

She is worried about a certain person (Amame). "Can she do everything as I said?" she wonders. Tokiko is going to cut her body in half with the slicer in the Horadori Institute basement. Then, she'll have Amame carry the right half of her body to the president's office.

  • Person appearing 1: Sack man

6 years ago, the person in the sack is Gen. Gen's face and skeleton are warped and unsightly due to Chikara's genome editing. Tokiko is not involved with the genome editing, but she knows about it through Chikara, and feels pity for Gen. Somewhere in her heart, she may have put her feelings towards her real son Jin Furue onto Gen.

  • Person appearing 2: Shoma

A child who, like Gen, had his genome edited. (His growth was slowed down after a certain point in time.) While she feels pity for him, he is also a precious follower of NAIX's teachings. Somewhere in her heart, she may have put her feelings towards Uru onto Shoma.

  • Branch: No

  • Final facts revealed

She knows that someone (Uru) has a plan called the "Nirvana Initiative." Ryuki heard about the Nirvana Initiative six years ago, so it feels familiar to him.

R12_somnium (Naixatloz's Intentions)

Suddenly, a blue figure and "Tokiko B" appear in the center of the bridge. "Tokiko B" is different from "Tokiko A sitting in the chair." Both exist at the same time. Tokiko A sitting in the chair is just sitting and not moving. The blue figure represents Amame.

The blue figure and Tokiko B are standing perfectly still in silence. The camera alternates between them motionlessly. After alternating several times, the left half of Tokiko B's face slides straight down for a moment.
A metaphor for her interaction with Amame. Change the camera to Tama's shocked face for a second. When it retuns to Tokiko B again, she is standing there and not cut. (Huh? Was the cut a mistake...?)

When you read it, 9 skulls (skulls A-I) will suddenly appear. Gen's skeleton and body have become distorted... She thinks of the many children whose skeletons were changed by Chikara's experiments. That's the metaphor.
[The black figures] don't do anything. If you leave, they disappear. If you don't get close, you won't see anything. (It's the opposite of the amusement park gameplay, you can't see it if you don't get close. Looks like a BT from Death Stranding.)

// →◎これからニルヴァーナ計画で死ぬことになる大量の人たち(をただ無感情に見ているだけ)
Outside the window, falling blue figures slowly flow from top to bottom. (6-8 people at most in a loop.) Tokiko is just staring at the bizarre scene outside her window. These are the many people who will die from the Nirvana Initiative (she just watches apathetically.)
