; : :A second-year high school student who discovers Subaru's secret. Frequently referred to simply as Jirō, he suffers
gynophobia resulting in nosebleeds whenever a girl touches him. This is the result of the abuse he suffered from both his mother and sister using him as a dummy to practice wrestling; seeing him bleed was the
only thing that stopped them, so his nosebleeds are self defensive. ; : :A second-year high school student who works as a butler for the Suzutsuki family and suffers from
aichmophobia. When she was young she was noted to be antisocial and was not close to anyone, which worried her mother. She dresses like a male due to family circumstances where one of the family has to serve Kanade's family as a butler. ; : :The daughter and only child of the high school's principal, who appears to behave as a rich man's polite and elegant daughter, but she is quite
sadistic. She enjoys tormenting and teasing Kinjirō by using his gynophobia against him. She does, however, give serious thought to finding a way to cure his gynophobia.

She is a member of the handcrafting club.

While initially annoyed by some of Jiro's traits or lack of abilities which Subaru has, she eventually sees him for who he is and eventually falls in love with him.
