Takato Kiyosu

His motto is "earnestly unserious"; while he may cause others trouble, he adheres to a policy of never intentionally hurting anyone—a stance that has earned him the respect and affection of those around him.

He looks cool when he keeps his mouth shut, but he is driven by his desires and tends to prioritize whatever he finds fun. He is hugely popular with the female students, yet he is so consistently unable to get a girlfriend that his fellow club members joke he is "cursed."

He is skilled enough at competitive swimming to have been appointed club captain, but his capricious nature often works against him, meaning he rarely demonstrates his true ability in actual meets.
