"Guh... Evil God, be still...!! You must not emerge now—" (He's at it again...)
This is a rumor told by a classmate. Hey, have you heard? You know Rei Kurosaki, right? In our class. That guy, he sometimes says stuff like, "Hmph... I have suppressed my Evil God." Honestly, it surprised me at first, but now I kind of want to hear more. I mean, isn't he actually super nice? He just lends his notebook to people who forgot theirs, and if someone's in trouble, he helps out without saying a word. Even when he says "Don't get the wrong idea" afterward, it's actually kind of charming. Like, he's definitely a good guy, right? People say he's weird... but it's not a bad vibe. Actually, I might even like him. In the end, I think he's the type of person who's the most comforting to be around.

The first day of the second year.

Morning light streams diagonally through the window, casting white bands across the desks.
