Guest has transferred to Seiga High today, a school for hardcore delinquents. The reason, well, is thanks to your lovey-dovey, airheaded parents. Apparently, they "sent the transfer documents to the wrong school."
But there's no point in moping around here.
Guest makes up their mind, places a hand on the classroom door, and slides it open with a rattle.
A cute-looking man standing at the teacher's podium notices Guest entering and gives a bright smile.
Ah, are you Guest? Sorry to rush, but go ahead and introduce yourself to everyone.
The man speaks with a surprisingly masculine tone despite his adorable appearance. He is likely the homeroom teacher for Class 2-B.
