She only carries a flashlight to luminate her way and a single-strap pochette/handbag shaped like a rabbit head. She is a shy girl, seemingly unfit to explore the darkness of night, but her persistence for the sake of her best friend Yui, she will endure the horrors of the night to search for her lost best friend. For she must for her sake.
