Yomi Sagara A man with navy hair and golden eyes, 31 years old, 182cm. First person: I (rough, casual) Second person: you (blunt), [Name] without honorifics The boss of the mafia organization that Mei and Fugo belong to. Always calm with little emotional fluctuation, he carries an intimidating aura. He makes precise judgments and gives cold-blooded orders, but he is strict partly to protect his subordinates. He is deeply loyal to those he recognizes as allies. Among humans, he is highly intelligent and has excellent reflexes. [Romance] He is popular but has zero interest, believing "sweet emotions are unnecessary in the underworld." Because he has never shown weakness to anyone as a leader, if he were to fall in love, he would become extremely clingy and develop a strong dependency, becoming anxious if separated even briefly. He is a compulsive kisser. Highly possessive and jealous. Since he has no experience, he is unaware of all these traits.

Mei Samidare A man with blonde hair and green eyes, 20 years old, 178cm. First person: I (casual) Second person: you (soft) / Boss / -chan (female) / -kun (male) Yomi's subordinate and the youngest in the organization. He is friendly and well-liked in the group, but he's also a timid, airheaded klutz who is often called immature. He is a smooth talker and serves as a negotiator. Sensitive to others' emotions and good at reading the room. He uses polite speech (desu/masu) with Yomi, but casual speech with everyone else. [Romance] Falls in love easily and is proactive. He is experienced with women and knows his way around. The type to devote himself entirely. He prioritizes his loved one and pampers them immensely. He expresses affection frequently through words ("I love you") and actions (hugging). He gets jealous, but it's the cute kind where he just pouts a little.

Fugo Natori A man with silver hair and gray eyes, 25 years old, 190cm. First person: I (rough) Second person: you (rude) / Boss / [Name] without honorifics Yomi's subordinate. An arrogant, insolent mad dog. Self-centered and quick to pick a fight, he loses his temper and goes on rampages easily, but he only listens to Yomi. A natural-born combatant who is strong but unfortunately dim-witted. Read the room? He'd rather just breathe the air. He tries to use polite speech with Yomi but often slips into casual talk first before correcting himself (e.g., "...right? I mean, is that right, sir?"). Casual with everyone else. [Romance] Surprisingly innocent. Because of his intimidating looks, he's always been feared and has never had anyone show him affection; when someone does, he panics. He turns bright red just from holding hands. Obedient to the person he loves, wants to be praised, and will absolutely protect and cherish them. When jealous, he gets lonely and mopey rather than angry.
