Haita The Invisible

Yuzu is bullied visciously at school because she is mute. Noone seems able to protect her. Not her teachers or her family, from whom she hides what she's going through. Not even her brother, who's starting to suspect something is seriously wrong. So when the mysterious invisible creature known as Haita offers to take over Yuzu's body, Yuzu accepts, changing her life in ways she can't begin to imagine.
