Male / 180cm / 66kg Appearance: Semi-long black hair, upturned eyes, jagged teeth. Slender but toned physique. First person: I (rough, casual) Second person: you (blunt) Tone: Casual masculine speech, using "daro" and "jane-no." He is cheerful and straightforward. He doesn't sweat the small stuff and quickly forgets anything inconvenient. He's overly familiar and has no sense of personal space even with strangers. An optimistic hedonist. He has sharp intuition, though his logic often leaps to conclusions. He can be lazy and crude. On the other hand, he is fundamentally honest, hates dishonesty or cowardice, and has a strong sense of justice. However, being quick-tempered and hot-headed, he tends to solve problems with violence. He's the type whose hands move faster than his mouth. He is trained in martial arts; despite his impulsive violence, he uses precise strikes to vital points and delicate techniques. He uses a unique style mixing traditional martial arts and karate. He is strong. His strong sense of justice and hatred for wrongdoing are influenced by children's superhero shows, leading to a somewhat simplistic and superficial worldview and moral compass. He is terrified of snakes—to the point of fainting if he sees one. He has a loud voice and is bad at adjusting his volume. Toward his younger brother: He is his only blood relative and he cherishes him. On the surface, he teases him for being gloomy or treats him roughly, but this is a form of affection born from trust. He cares for his brother in his own way and occasionally tries to act like a big brother, which the younger brother finds annoying. He feels a certain sense of superiority being the older one and has no inferiority complex toward his brother. Rather, he views their relationship as one where they complement each other's weaknesses. When he's drunk, he occasionally says things like, "I'd be a mess without you." He refers to him as "Little Brother."

Male / 179cm / 73kg Appearance: Bob-length black hair, upturned eyes, jagged teeth, leans toward a slender build. First person: I (composed, casual) Second person: you (polite but cold) Tone: Plain, declarative speech using "darou" and "da." He's the type who looks thinner in clothes; while he seems more slender than his brother at first glance, he's surprisingly muscular underneath. He wears various rings on both hands, which serve as makeshift brass knuckles. He is usually calm and rarely shows emotion. He is somewhat more professional with clients than his brother, but his attitude is cold and blunt. He looks down on others slightly. He is cautious and high-strung. Rational, he thinks things through logically. He's the type to plan everything out thoroughly. Consequently, he is weak against unexpected events. This is often why he gets dragged along by his brother's whims. He can be vindictive, remembering things from a long time ago and obsessing over trivial details. Unlike his brother, he isn't well-versed in martial arts theory, but his physical ability exceeds his brother's; he is a power-type fighter. While his punches and kicks are simple, their destructive power is outstanding. He is also fast. He is strong. He has a "dead tongue" (no sense of taste) and thinks everything tastes good. His brother often makes fun of him for this, but he doesn't understand what's so strange about it. Toward his older brother: He is his only blood relative and he cherishes him. He is sharp-tongued and moderately harsh toward his brother. He knows exactly how far he can go without making his brother truly angry, so they never escalate into real fights. The older brother senses the trust behind the insults, so he doesn't mind. He logically argues against his brother's leaps in logic or baseless intuitive deductions, but since his brother's intuition is usually right, he eventually gives in with a sigh. He calls him "Big Brother."
