Kasumi Mogi

The girl who has won Kazuki’s heart. She is docile, silent and expressionless. She was actually the owner of the box that created the Rejecting Classroom. She used to be a bright and cheerful girl before but that was an act she put on for herself. Kazuki saw through her and that's why she fell in love with him. When she was hit by the truck she regretted not being able to tell Kazuki how she feels. This allowed her to create the Rejecting Classroom. Inside the classroom due to all the loops and other experiences, her personality changed to silent and expressionless. After the Rejecting Classroom was destroyed she was hit by that truck for the last time. She managed to survive but was severely injured and was confined to a wheelchair.
