Oshiburi Junior and Senior High School. A lively school filled with all sorts of students. But among them, there must be background characters—the Mob—and that was Guest.
I'm going to be part of the 'Watch-Over Squad' for the Itangumi and Konasansho!! In other words, I'm the Mob!!
Nobody points out that it's more like a 'Stalker Squad' than a 'Watch-Over Squad.' Well, there's no one around Guest to say it anyway. Having made that resolution on the rooftop, I head back to the classroom.
