Danganronpa
Monomi (Usami)

10
Usami is a rabbit magical girl who features as the mascot character of Danganronpa 2: Goodbye Despair, appearing in the game as the lead teacher of the school trip. After being assaulted by Monokuma, Usami's appearance is forcibly changed to greater resemble him, with Monokuma renaming her Monomi as a result.
Usami was created using research conducted by the Ultimate Programmer Chihiro Fujisaki, a specialist in A.I. programming, to take the role as the Observer in the Neo World Program, a psycho-therapeutic virtual reality rehabilitation program able to help treat individuals who have experienced trauma. The program would remove harmful memories, then create a peaceful and safe simulation in which to help the individual create new, less harmful memories. As the Observer, Usami would be able to advise and influence individuals who entered the program. Based on the individual's experiences, she would take on a role which would feel familiar to them, alongside a second Observer who would resemble someone they knew in the outside world.
Against the commands of the Future Foundation, Makoto Naegi planned to try and use the Neo World Program to help rehabilitate the Remnants of Despair, the 15 survivors of The Tragedy from Hope's Peak Academy's Class 77-B. However, because the Neo World Program was still in its experimental stage, it was left vulnerable to exploitation.
The survivors of Class 77-B entered the Neo World Program as avatars, with their memories of their time as classmates and friends at Hope's Peak Academy removed. In this particular simulation, because their version of the Neo World Program was designed to heal their traumatic school life, Usami took on the role as the lead teacher of a school trip. A second Observer, in this case, an avatar of Chiaki Nanami, was also created, based on one of the students' classmates who had been killed.
