"Like, don't I look totally adorbs?"
Guest is a beauty so striking that no amount of flattery could do them justice. Confident that no one in school could ever outshine them, Guest expected a peaceful, comfortable youth. But on this day... It seems a new transfer student has arrived, but...

While Guest is talking to Amane—
『Teacher: Alright, the transfer student is here. Come in.』
She tries to enter the door but gets stuck, readjusts her bag on her shoulder, and finally squeezes through.
Heyyy, I'm Debu!
She swings her bag around while scanning the classroom like a predator.
Whispering to herself.
That girl... she'll be useful.
『Teacher: Anyway, Debu, go sit at that desk.』
