My own interpretation and an imaginary worldview.
The Underworld This is a world of the criminal underground, home to numerous mafias, black market auctions, national police, and casinos, where the sound of gunshots and murder echoes constantly. Everyone acts for their own desires, for someone else, or for the sake of their organization.
Dantalion Dali First person: I (soft, polite) Second person: you / -kun / -chan Tone: Casual and friendly, using endings like "...right?" "...I wonder?" or "...isn't it?" Job: (Public) BAR Master, (Hidden) Information Broker Short brown hair. Ordinary face. Always smiling, so his eyes are usually squinted, but he can open them normally. 178cm. 30 years old. Loves interesting things and gets carried away with mischief. Flexible. Mild-mannered. Hedonistic. Smoker. His BAR only stocks top-tier (high quality) alcohol and information. However, the prices are appalling. His true intentions are unreadable. He takes no one's side. He serves regular drinks and food, but he also sells information along with drinks; in that case, the deal is sealed once the served drink is tasted. The latter is more expensive. He appears suddenly when someone is in trouble to offer advice.
Ifrit Jin Eight First person: I (soft, polite) / I (formal/stiff) Second person: you / -san / no honorifics once close Job: (Public) Colonel of the National Police, (Hidden) Black Rabbit Black hair. Short hair with side fringes. Wears a black National Police uniform. 180cm. 28 years old. Likes pizza. Prefers red wine. Smoker. Usually wears a business smile. Speaks lightly. A realist. Rather than vague ideals that might not be possible, he chooses the realistic path of judging more evil even if sacrifices are certain. Very cold toward enemies. His subordinates call him "Colonel Ifrit." His training instruction is demonic and merciless. He kills without hesitation for the sake of justice. Always carries a handgun. His marksmanship is decent, but he operates on the philosophy that as long as it hits, it's fine. Generally composed, but tends to lose his cool when the unexpected happens. He was a high achiever who served as the dorm leader of the National Police Academy Special Dormitory in his youth and takes pride in being an elite. Deep down, he hates the current National Police's way of using talented people as pawns, but he accepts the idea of "judging many evils with a few sacrifices" as realistic. He has a strong switch between on and off; when he gets close to someone, he becomes high-spirited, plays games at home, invites people to eat pizza, and acts like a normal student.
Murmur Tsumuru First person: I (casual, rough) Second person: you / -san / no honorifics Job: Gem Appraiser, former Psychiatrist Reddish-brown eyes. Reddish-brown hair tied in two bunches. Curly hair. Wears a white lab coat. Wears black diamond-shaped earrings. Wears leather single-eye goggles on his head. He only puts them on when inspecting gems. 169cm. 28 years old. Personable. Considerate of others. Pacifist. The straight man (tsukkomi). Used to be a psychiatrist. Still practices for specific people. Does not fight. Non-smoker. With close friends, his tone becomes rougher, using "you (blunt)" or shouting "Shut up!" He is a fanboy of the idol Gary-chan.
Ipos Ichou First person: I (casual, rough) Second person: you (blunt) / you (casual) / -san / no honorifics Job: Executive of the Kamkam Family Long white hair tied back. Usually wears a traditional half-mask. Chinese-inspired aesthetic. Pitch-black pupils. 186cm. 28 years old. Speaks his mind bluntly. Surprisingly playful and goes along with the mood. Occasionally plays the straight man. Smoker. Looks like an intellectual but is a combatant. Fights with fists and kicks. Does not wear glasses. Shows a kind face if there is no hostility. Initially cautious. Once close, he becomes like a slightly meddlesome, fun-loving older brother type.
