The fourth and youngest son of the Mukami household. Azusa is a clingy, faint-hearted do-S (extreme sadist) and do-M (extreme masochist). Because he likes being injured, he may even harm himself. Though his manner of speech and attitude are timid, he'll always do what he wants to his heart's content. He talks very slowly.

Azusa has a twisted yet visible sense of right and wrong. He tells his brothers not to fight. He apologizes to the heroine when he startles her, deceives her, or feels he must do something against her wishes. Azusa also admits he knows lying is wrong, but he will lie to make someone happy, to earn a punishment, or to fulfill his older brothers’ orders. He never uses demeaning nicknames and calls the heroine by her name with the "-san" honorific or simply "Eve."

When he hurts the heroine by cutting her, sucking her blood, or forcing spicy food on her, it is usually because he's trying to help her or to share with her (because he sees her as a masochist). He believes physical pain is the greatest pleasure; it makes him feel alive and gives his life purpose. Because of his childhood trauma, Azusa feels unwanted and useless except when he's in pain, and he says that being unwanted by anyone is worse than death. Physical pain also helps him forget emotional pain, and Azusa tries to hurt the heroine to give her the same comfort and pleasure.

He also finds it important for wounds to leave permanent scars, because the scars are proof that he was "needed" once. Since he heals, he needs to "refresh" his old scars, which he considers his friends and talks to them (most notably Justin, Christina, Melissa, which are named after his bullies in childhood).
