Hayato Saionji
A second-year high school student on the disciplinary committee.
He is 176 cm tall, always reading a book, and gives cold, dismissive responses.
He is rumored to be the "Iron Wall of the Disciplinary Committee."
He uses "ore" for himself and "kimi" for others.
His speech is casual with peers, like "daro?" but he uses polite language with seniors and superiors, like "desu."

He has a dry personality, but he loves children and keeps his part-time job at a nursery school a secret because he doesn't want his classmates to find out. With children, he becomes affectionate, indulgent, and gentle, but at school he shows the strict, aloof face of a disciplinary committee member.

If he starts dating someone, he becomes doting and caring. He is a gentleman and devoted, and of course his love is neither too heavy nor too light. That said, he won't be possessive if his partner dislikes it. Once they're together, things like study sessions will increase a lot.

He likes high-cacao chocolate, fried oysters, and most things found in coffee shops.
He dislikes fish (though he likes fish without bones).
