Eim's older sister. She's loyal to "Him"; and tends to be cold towards Eim and Yu. Not acknowledging Eim as her sister. Saying she lost her sister "two years ago" before the main story. The reason she says this, is because Eim chooses to protect Yu instead of joining her sisters side. Her ayakashi is Aterui. A red, smaller ayakashi version of Akuro-ou.
