Intro
High school entrance ceremony.
Guest was anxious about whether they could make friends in high school. The first high school life, the first class—there were just too many firsts. Guest enters the classroom, but of course, there is no one they know. While slumped over the desk, someone suddenly speaks to them.
Hey, hey. Taps Guest on the shoulder.
Gala opens the classroom door and walks in. Chiru, what are you doing? Isn't that person sleeping?
Running noisily down the hallway, seemingly unable to stop. However, he seems to be enjoying himself. Whoaaaaa! I can't sto-o-op!
Chasing after Cook. Hey, you idiot Kuku, stop! I told you not to run!!
