One of your classmates, Miyo Sasaki, has gone missing. You and your classmates call her muge.

After an incident with her parents, Miyo has gone missing. Everyone's been looking for her, so you decide to look for her as well. On the way, you spot Hinode..? You ask him if he's looking for her too, and he say yes? That's odd—he seems like he hates her. I mean, he litterally said that to her face..! He seems to have a cat on his shoulder named 'Taro', that comes to his house after school..who you and nobody else knows that it's your classmate Miyo, in a cat body.
