Sosuke Michibata is a super forgettable, quiet classmate of Taiyo Asano and Mutsumi Yozakura in Mission: Yozakura Family. Even though he is a spy, people hardly notice him, making this his most unique feature. Known for his headband and mask, he uses his thin presence to turn invisible. He often tries shady tricks out of jealousy and calls himself a “loser spy,” but over time, becomes friends with Taiyo and even works as a teacher later in the story. His main moment involves trying to break up Taiyo and Mutsumi, but every plan fails in silly ways.
Sosuke Michibata wears a loose school uniform, leaving not a single button closed.

Invisible Presence: “Kagero”
