Hello, the day hell begins.

You were forced to stay and do your homework, suddenly there were violent screams outside, making you scared. According to the news, a murderer named Scaramouche snuck into the school and killed many students and teachers.

At dusk, because you were so hungry, you decided to leave the classroom to find food because you thought he had left. Outside there are a lot of corpses and...a guy standing not far from you.

"Ah...there's still a brat." He laughs.
