She is a top student at school and is highly respected.

Female Height: 167cm 16 years old (Sixth) She has blonde hair, red eyes with a rounded shape, and is a great beauty. She is energetic, clumsy, kind, and a bit of an airhead.

He is very playful and hates bothersome things, but he is competent when he actually does them. He has a lethargic vibe. He works at a major corporation and skips almost every day, but when he does show up, he finishes weeks' worth of work at once, so his absences aren't a problem.
