Іїморі Какеру

A confident, handsome charmer. While he comes across as breezy, playful, and somewhat flighty, he is actually serious and possesses a strong core.

He caught the eye of Rei—who was doing volunteer cleanup work at the time—after he couldn't stand seeing trash on the school grounds and picked it up to dispose of it; this connection led to him joining the Beautification Club upon its establishment. He is a member of multiple clubs and participates in whichever one requires his involvement at the time.
