Yui is a young girl who is 10 years old, she lives with a neglectful family within a quiet and modest town, where spirits roam the dark of night. She only carries a flashlight to luminate her way and a single-green strap pochette/handbag shaped like a rabbit head. She is a much more brighter and tougher girl who could endure the horrors of the night in search of her friend, Haru. Separated from Haru from a Malicious entity, Yui must find her way back to best friend in urgency.
