The protagonist of the story. A second year high school student who discovers Konoe's secret. He suffers gynophobia in which his nose bleeds whenever a girl touches him, he reveals the cause to be his mother and sister practicing their wrestling moves on him on a daily basis for 10 years, he states his nose bleeds when a girl touches him because his body developed the reflex because he believed his mother and sister would stop beating him up once he started bleeding (as his blood would ruin the carpet). As a result can take pain well due to his everyday awakening from his sister, Kureha Sakamachi, with a series of beatings. He was forced to sign a contract with Kanade Suzutsuki to not reveal the secret of Subaru Konoe and find a way to cure his gynophobia. He hates it when people call him his full name as, due to the Japanese culture of putting the familiy name before their given name, it creates a pun on the english word chicken as his full name is Sakamachi Kinjirō.
