**Sekiba High** (隻芭女子高, *Sekiba Joshikō*, TL: Sekiba Girl's High School), or just **SJ** for short, is a location featured in *AI: THE SOMNIUM FILES - nirvanA Initiative* and mentioned throughout *AI: THE SOMNIUM FILES*.

Sekiba High is an all-girl's high school attended by Iris Sagan and various other characters. Students attend school wearing uniforms made up of a white buttoned shirt, a red tie, black loafers, and a mid-thigh black dress with a bow on the back, the school logo emblazoned on the shoulders, and four buttons down the front that also bear the school symbol.

## Story

### Side Ryuki

Iris Sagan, Amame Doi, Kizuna Chieda, and Bibi all attended Sekiba High from the ages of 15 to 18. By Bibi's own admission, however, she did not attend school that much, and isn't even that familiar with the building. On February 11th, the day after Jin Furue's body mysteriously appeared at Studio Dvaita, Kuruto Ryuki visited the high school to get more information out of Iris, who had been present when the body appeared. That was when he first met Amame Doi, who had joined Iris in coming to school despite it being a holiday (when asked why, Iris said that she felt compelled since she'd be graduating soon and wouldn't be able to come to the classroom for much longer). While talking with the two girls, Gen Ishiyagane also appeared, explaining that he could get into the school building despite his appearance because of the lax security. He mentioned that the school had guards, but there were many areas of the campus that lacked fences or security cameras.

Later on that night, Chinpei Wagai received a text from Tearer telling him that, in exchange for letting Tearer use Studio Dvaita, Chinpei would be rewarded with five million yen that he could retrieve at Class 3-A of Sekiba High. Ryuki went to the school in his stead and found the right half of Chikara Horadori's corpse suckered against the chalkboard.

Class 3-A was barred off due to becoming a crime scene, and was only visited once more in Not All A Dream when Ryuki wanted to check the scene for any clues that could lead to the missing Kizuna. He didn't find anything, however, and resumed his search elsewhere.

### Side Mizuki

Mizuki Date was attending Sekiba High as a senior when the Half Body Serial Killings abruptly resumed with the appearance of half a corpse at Tokyo National Stadium. Mizuki convinced Boss to let her on the case and then went to Sekiba High to get a refresher on the appearance of Chikara's corpse. Instead she found Ryuki there, sitting on one of the desks and in a state of mental instability. She tried to coax information on the case out of him, but Ryuki was in no state to talk and eventually left to clear his head at Ikume Shrine. Mizuki left the building quickly after.

The next day, Ryuki used his VR Vision while at the shrine so that he could investigate Chikara's corpse at Sekiba High from six years ago. He confirmed Chikara's time of death and found that the body was able to stick to the chalkboard because its internal organs had all been removed. He then exited out of the VR space.

Sekiba High didn't make a further appearance in *nirvanA Initiative*, but the fact that it was used to dispose of Chikara's body ended up being an important clue to stopping the Nirvana Initiative.

## Design

Sekiba High is a modern, four-story high school with a cream and blue color scheme for the exterior. It is surrounded by a low brick wall with a security gate at the entrance. The school's name is on a green placard next to the gate. Various shrubs and trees line the inner grounds of the campus. The doorway to the school is covered by a semicircular portico held up by thick white pillars.

Class 3-A is a typical Japanese classroom with space for 30 desks lined up 5x6. The front and back walls of the classroom have almost room-wide chalkboards, with space on either side for noticeboards covered in white and yellow sheets of paper. Below the back chalkboard is a long line of small lockers for the students, ending in a storage cupboard in the back corner of the room. Various boxes can be seen atop the lockers, and a dusting pan is set next to them against the wall. The left wall is mostly windows with curtains that are kept open throughout the game. At the front left corner of the room, above the chalkboard, is a flat-screen television. At the front of the room is the teacher's desk. On the right wall are two doors leading out of the front and back of the room.
