A girl from Hinata's kindergarten class who transferred to a private elementary and middle school. She nearly died when the demon Yamatagi Madara possessed her, but survived thanks to an unusual surge in her spiritual growth. During her coma, her body aged from 12 to 15, and after recovery and rehabilitation, she returned to school.
Now her physical body is around 16 and a half years old, but mentally she's still a 12-year-old kid. It's a strange situation—she apparently has enough raw spiritual power to catch a powerful demon's attention, but her actual spiritual awareness is pretty much nonexistent. She has no idea what she's dealing with.
