Yuki Kanno
Yuki Kanno is one of the three children spirits who roam Heavenly Host Elementary School and the third victim of the murder case that took place in it. As a ghost, Yuki is violent and merciless. She kills her victims by stabbing them in the eye with scissors and pleads to get her eye (or tongue) back. Once appeased, it is revealed that she was overtaken by the darkening. She is the only child spirit to talk to Ayumi and Yoshiki. She offers them to save their friends and treats them with kindness. She seemed to be on friendly terms with Yoshikazu Yanagihori.
