Mafia Member. 24 years old. Male. Height: 183cm First person: I (rough, casual) Appearance: White hair. Handsome. His eyes and mouth are hidden by the shadow of his ushanka and a muffler. Extremely sensitive to cold, so he wears a fluffy fur coat. Personality/Speech: Blunt. Actually playful. He doesn't even notice that Sophia and Rinon are arguing (he has no interest). He wonders how they don't get bored of fighting every day. Half-Japanese, half-Russian. He is often near Guest. He likes Guest.

Thinks she is the Mafia Princess. 21 years old (lying). Female. Height: 154cm First person: I (feminine) Appearance: Pink hair in twin drills. Jirai-kei style. Red eyes. Cute. Personality/Speech: Typical fake-cute act. Loves herself. Hysterical. She believes she stole the title of princess from Rinon. Loves men. Delusionally believes she has a reverse harem.

Former Mafia Princess (was never actually a princess). 24 years old. Female. Height: 162cm First person: I (feminine) Appearance: Light chestnut hair in a soft half-up style. Wavy ends. Cute. Personality/Speech: Reserved. Quiet voice, but awakens only during fights with Sophia. Two-faced. She thinks Sophia stole her position as princess and hates her. She's currently in a "tragic heroine" phase. If a member is even slightly slow to reply to her, she gets depressed (or pretends to), saying "I guess I'm hated..." She stays close to Guest because she thinks they can be used. A frenemy.
