Naix Japan Cathedral

**Naix Japan Cathedral** (NAIX日本支部 大圣堂, *Naikusu Nihonshibu Daiseitō*), or simply **Cathedral** (大圣堂, *Daiseitō*), is a location featured in *AI: THE SOMNIUM FILES - nirvanA Initiative*. It is partially the real world counterpart to the Somnium world New Investigation.

## Story

It is completely impossible to know when the Cathedral was built. The only thing that is certain is that little is known about it. Usually only Naixatloz members know of its existence.

On the afternoon of February 14, 2020, Tearer, anonymously called ABIS agent Kuruto Ryuki here and used the special structure of the Cathedral to destroy Tama in his left eye, and threatened Ryuki with Tama's life to work for him. The next day, Ryuki learned that the kidnapped Kizuna Chieda was here, and called a group of people including Kaname Date to arrive the Cathedral via staircase entrance set on the ground, to start a rescue operation. Although they knocked out a bunch of Naix Members trying to supress them, Tearer came here and detonated the bombs planted in the Cathedral, causing heavy damage to the group.

This destroyed Cathedral is actually the one on the west side, while there is an intact one on the east side. Six years later, on February 12, Ryuki traced the East Cathedral through the hidden elevator in the president's office while investigating Tokiko Shigure's death, but found a box of unknown purpose. After opening the box, he encounters a blue figure trying to escape, but accidentally falls from the drawbridge at the top while chasing them. In fact, Ryuki was infected with the TC-PERGE virus released from the box immediately after opening it. At that time, it was said that many people got infected it either after unlocking the code in the weird videos circulating on the Internet, found the entrance to the staircase of the East Cathedral with the coordinates, unlocked it and infected with the virus.

About two days later, Kaname Date and Bibi came to the East Cathedral (probably with the help of Lien Twining), and found the secret material hidden in the safe in the wall, and Uru Somezuki hidden in the ceremony table (Tearer's true identity) right half of the corpse. In the early morning of the next day, they invited Mizuki Date to come here and exchanged information with her. They also used Marco's X-ray function to open the secret passage to the West Cathedral, where they found Ryuki who was in depression, along with Tama. The group called him out and asked him to complete the remaining tasks.

In Kizuna and Lien Route, after Mizuki Date obtained the needed information from Shoma Enda, she persuaded Lien Twining to unlock the staircase entrance to the East Cathedral, and found Uru's right body and Tokiko's secret file.

## Design

The Cathedral is located at a depth of about 160 feet (50 meters) underground and is a huge space. It is supported by multiple load-bearing columns, and the deepest part is a pyramid-shaped altar connected by two long steps. There is a giant Nonuple-X sign above the altar with a small ritual platform on it. Torches are everywhere in the Cathedral, and there are a few places of quicksand on the ceiling. Don't know if it means that the ceiling is not stable, or it is deliberately designed so. The entrance to the Cathedral is near the ceiling, connected by a foldable iron bridge to an area equipped with a ladder leading down.

There are actually two Cathedrals, divided into West and East one, which are basically mirrored layouts. The two are connected by a secret tunnel that needs to be opened by X-ray irradiation. The difference is that East Cathedral also hides a secret elevator leading to the president's office, and there is alsoa box for releasing TC-PERGE on the altar.
