Ought to Know

Ryuki Diverge:* 遐ｴ邯ｻ逋ｾ蜃ｺ

**2/11 Ryuki Chapter 1: Ought to Know** (２月11日 龍木編 １章: 半解, *2-Tsuki 11-nichi Ryuki-hen 1-shō Hankai*, lit. **11th Feb Ryuki Chapter 1: Half-knowledge**) is a chapter featured in *AI: THE SOMNIUM FILES - nirvanA Initiative*.

It is the sixth chapter of Ryuki's Routes. It follows Ryuki's investigation of a lead from Chikara Horadori's Somnium.

## Case File Synopsis

Inside Chikara's Somnium, Ryuki and Tama saw something...

A member of Naix creating the Bats490 video.

Ryuki decides to head to Naix Japan Branch to talk to Tokiko, the president.

Tokiko admits Bats490 was created to recruit new members. But she says it's not related to the QR video. During the conversation, she mentions "Frayer." "Fray" was a word on the signboard. It's hard to believe it's coincidence, but Tokiko insists its just a "bug." She says that is also the case with Jin's body being found...

After an investigation, it is determined that the appearance of the body was only made to look as though supernatural forces were involved. The show director, Chinpei, says that he lent the studio to a person named "Tearer." Tearer sends a message to go to Sekiba High... Ryuki immediately heads there...and finds Chikara's right half stuck to the blackboard.

## Story Summary

### Naix Japan President's Office, 20:05

Ryuki visited the office of Naixatloz Japan Branch to speak to the president, Tokiko Shigure. Ryuki had found the building through one of Boss's connections, and Tokiko's secretary Mamoru Bodai had let him in. Tokiko explained to Ryuki that the rumors and urban legends about Naix were untrue, and they instead believed in simulation theory. Tokiko believed the world was a simulation created by someone, and wish to tear at the program's "seams" to free its people. She spoke of a prophecy, that the seam would occur at the intersection of warp and weft. Tokiko admitted that Bats490 was created by Naix as an ARG for recruiting high-IQ individuals into the organization. She also explained that Chikara was a former member of Naix, but had become a believer in the Order of % over 20 years prior.

At one point in the conversation, Tokiko asked, "Are you a Frayer?"

#### Are you a Frayer? -> No

Ryuki did not understand her question, but was reminded of "Fray to Free" from the QR video. Tokiko insisted it was a coincidence, a result of a glitch or seam in the program. She explained the Philadelphia Experiment to Ryuki, an incident in which a warship disappeared, then reappeared, but its crew had been disfigured in ways that seemed supernatural. Tokiko believed the state of Jin's body similar, and a result of a glitch.

#### Are you a Frayer? -> Yes

Ryuki answered "yes" and told about the "nil number" he got by some means, after Tokiko asked for it. Then, something strange happened.

### Yoyagi Park, 22:05

The rest of events only occurs in the "I'm not a frayer" branch.

Ryuki and Tama visited Yoyagi Park to think over the case. While they wondered about Jin's apparent teleportation, Tama suggested a way to find out what happened for themselves.

### Studio Dvaita (VR), 22:10

Tama recreated the crime scene at Studio Dvaita in Virtual Reality from a scan she made the previous night. Ryuki explored the recreation to search for clues. Jin's body appeared to have a thermite bomb inside, and the signboard with the QR code was lodged deep inside. There were bundled carbon nanotubes tied to his body and attached on the other end to the light switch.

### Studio Dvaita (VR), 22:30

Ryuki and Tama went over the facts to figure out what happened. They first determined that the blackout was not a power outage, but rather the lights being flipped. Ryuki determined that the body had been in the ceiling beams with bundled carbon nanotubes attached to it. The other end of the CNTs were tied to the switch, so when the body's rigor mortis softened, it fell and pulled the switch. The impact of the body hitting the floor triggered the fuse inside the body. Once they had figured everything out, Tama made Ryuki act out the culprit's actions.

### Yoyagi Park, 22:50

Back in Yoyagi Park, Ryuki and Tama concluded that the culprit wanted to make the body's appearance seem like a supernatural phenomenon. Since the quiz show ran for 6 hours, they did not need to time it precisely, and the signboard was used to make sure the body landed upright. The culprit must have had access to the studio before the show, so Ryuki and Tama decided to meet with the show's director, Chinpei Wagai.

### Maid Cafe Sunfish Pocket, 23:20

The moment Ryuki stepped foot in Sunfish Pocket, Chinpei spotted him and began shooting. Ryuki dodged the shots and quickly stopped him. Chinpei explained that he needed money to take care of his kid on the way, so he accepted an offer from someone named Tearer. Tearer asked to borrow the studio before the stream, and promised to pay him the following night. During their conversation, Tearer sent another messaging telling Chinpei to come to Sekiba High.

### Sekiba High, 23:55

Ryuki went to Sekiba High and found the body of Chikara Horadori stuck to a classroom blackboard.
