Hiyori Kotobuki

Driven by a restless spirit, this deceased girl remains trapped in the mortal realm, unable to find eternal peace or pass through the gates of heaven. As a wandering ghost, she possesses the ability to inhabit Mitsuki’s physical form to interact with the living. While occupying this body, she frequently pursues Yuuya with bold and provocative romantic advances, complicating the dynamics between the characters as she struggles with her lost soul.
