Ms. Morimura (Mystery Files)
For the main page regarding this character, see: Chihiro Morimura.
The Sakura High School nurse who's also the homeroom teacher of Class 1-B, which Juro Kurabe and Iori Fuyusaka are in.
Morimura learns from a 2188 log that the 2188 Morimura is responsible for the end of humanity. Fearing that the others will discover this truth, she discreetly deletes the log. Moreover, when Morimura links up to the artificial satellite in orbit, she finds out that the stability of the facility, which is responsible for maintaining the world, is at its breaking point. She then decides to set Operation Aegis in motion to completely wipe out the kaiju, even if it means stranding them all in a dead world.
In order to become compatible, she tried to overwrite her memories and personality into Fuyusaka and take over her body, but gave up on it after hearing that a loop was no longer possible.
Ms. Morimura has been in love with Juro Izumi since she was young.
The grown-up version of Chihiro Morimura, from two loops ago. When the world was reset, the Morimura that was saved in Sector 0 continued into the new world as a simulated personality.
