Toaru Kagaku no Railgun
Level Upper Arc
- Main article: Level Upper Arc
It is first visited by Shirai Kuroko and Misaka Mikoto, when they realized that Kaitabi Hatsuya has collapsed and is in a comatosed state. Here, they realize that many other people have similar symptoms, and has hired Kiyama Harumi, an AIM specialist to aid in the investigation.
It is revisited later duing the AIM Burst's rampage, where the comatose Level Upper users experience pain before being relieved of it after Uiharu Kazari played the Level Upper treatment program.
List of known patients
- Kaitabi Hatsuya
- Okahara Ryouta
- Juufuku Miho - only seen in a list of patients that have recently collapsed for reasons unknown.
- Koujun Kikuhiko
- A similarly named institute, Mizuho Organization Pathology Analysis Laboratory, plays a minuscule role during the Sisters Arc as one of the laboratories part of the Sisters Project and Level 6 Shift programs. It appears as if both institutes are managed by Mizuho Machines, especially given that Kiyama was aware of the existence of the Radio Noise Project after she was a researcher at this Medical institute (as shown only in the manga).
