## Suicide of Tokiko Shigure

### Location

The **suicide of Tokiko Shigure** was an event that occured in *AI: THE SOMNIUM FILES - nirvanA Initiative*.

Tokiko Shigure's death was somewhat unnerving to the police departament, not only because of how important the victim was, but also because it seemed to be some sort of continuation of the infamous unsolved Half Body Serial Killings from 2020. On February 12th Kuruto Ryuki had a planned meeting with Tokiko at 22:00 in her office, but upon arrival he and Tokiko's boduguard only found the right half of her corpse laying on her desk. This, and finding "Jin Furue's" left half two days earlier, made the police conclude that Tearer is on the killing spree again.

## Official Case Results

Amame Doi was officially found out as the assistant in Tokiko's suicide and the culprit of Uru Somezuki's murder and it was said she will be tried for these crimes. It is noted, however, that circumstances surrounding the murder will most likely strengthen Amame's court defense and grant her a short, if any, sentence. The ultimate outcome of Amame's trial is not revealed in the game, however.

## History

On February 10th, 2026, Uru Somezuki invited Amame Doi to his hideout in the underground of Horadori Institute of Genetics, where she killed him with a nearby wrench to avenge her father, whom Uru killed 6 years ago. There was a witness to the murder: Naixatloz's Japan Branch president and the main founder of Uru's plan, Tokiko Shigure. Catching her on the spot, Tokiko decided to blackmail Amame in order to fulfill her own plan of achieving Moksha, first by planting left half of Uru's corpse on the Stadium, then by assisting in Tokiko's suicide on Feburary 12th by planting right half of her corpse in her office, and leaving the other at the slicer under the Horadori Institute. Amame did both of those things and overall did her part in the plan, but she was eventually found out as the killer and suicide assistant by ABIS members psyncing with her and the Nirvana Initiative was stopped. Tokiko's own plan to achieve Moksha was still in motion though - on February 22nd Mizuki and Bibi visited late president's office, asking themselves about Tokiko's motives to kill herself and make Amame plant corpse halves in targeted locations. There Tokiko's hologram appeared and revealed to the Frayer a "nil number", which they could use to create a seam in the false world and help her achieve Moksha. Whether or not did Tokiko's plan work out, that is up to the Frayer, which may or may not result in achieving Ryuki Diverge ending.
