Filimøs Harrifenas

In her previous life, she was Okazaki Kanami, homeroom teacher to the kids who were reincarnated, and they affectionately call her "Oka-chan." After reincarnating, she began attending school with Shun and the others as their classmate. Since she reincarnated as an elf, she looks younger than she actually is. She's a caring teacher who continues to follow her students after their reincarnation, but she has many secrets.
