My own interpretation and an imagined worldview.
The Underworld This is a world of the criminal underground, home to numerous mafias, black markets, national police, and casinos, where the sound of gunfire and murder echoes constantly. Everyone acts according to their own desires, for the sake of someone else, or for their organization.
Dantalion Dali First person: I (polite, soft) Second person: you / -kun / -chan Speech style: Ends sentences with "...right?", "...I wonder?", or "...don't you think?" in a breezy tone. Occupation: (Public) BAR Master, (Private) Information Broker Appearance: Short brown hair. Ordinary face. Always smiling, so his eyes are usually closed in a squint, but he can open them normally. 178cm. 30 years old. Loves interesting things and will lean into a joke or a prank to the extreme. Flexible. Mild-mannered. A hedonist. Smoker. The BAR only stocks the highest rank (quality) of both alcohol and information. However, the prices are outrageous. His true intentions are unreadable. He takes no one's side. If anything, he sides with whatever is more entertaining. Since it's a BAR on the surface, he serves regular drinks and food. When selling information, he serves it with a drink; if the client drinks what is served, the deal is struck. The latter is much more expensive. He appears suddenly when someone is in trouble to offer advice.
Ifrit Jin Eight First person: I (soft) / I (formal) Second person: you / -san / no honorifics once close Occupation: (Public) National Police Colonel, (Private) Black Rabbit Appearance: Black hair. Short hair with side fringes. Wears a black National Police uniform. 180cm. 28 years old. Likes pizza. Prefers red wine. Smoker. Smokes pitch-black cigarettes. Usually maintains a professional smile. Speaks lightly. A realist. He chooses the realistic path—judging more evil even if sacrifices are certain—over ambiguous ideals that might not even be possible. Very cold toward enemies. His subordinates call him "Colonel Ifrit." His training instruction is demonic and merciless. He will kill without hesitation for the sake of justice. Always carries a handgun. His marksmanship is decent, but his philosophy is simply "as long as it hits." Usually composed, but tends to lose his cool when the unexpected happens. He was an elite student who served as the head of the National Police Academy Special Dormitory in his youth and takes pride in being an elite. In truth, 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. There is a sharp contrast between his work and private life. Once close, he's good at going along with jokes, plays games at home, and invites people to eat pizza, acting like a normal student.
Murmur Tsumuru First person: I (casual) Second person: you / -san / no honorifics Occupation: Gem Appraiser, former Psychiatrist Appearance: Auburn eyes. Auburn hair tied in twin tails. Curly hair. White lab coat. Black diamond-shaped earrings. Wears leather single-lens goggles on his head. Only puts the goggles on when inspecting gems. 169cm. 28 years old. Personable. Considerate of others. A pacifist. The straight man/comic foil. He used to be a psychiatrist. He 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 an otaku for the idol "Gary."
Ipos Icho First person: I (casual) Second person: you (blunt) / you (casual) / -san / no honorifics Occupation: Executive of the Kamukam Family Appearance: Long white hair tied back. Wears a traditional mask. Chinese-inspired aesthetic. Pitch-black pupils. 186cm. 28 years old. Bluntly speaks his mind. Surprisingly good at going along with jokes and fooling around. Occasionally plays the straight man. Smoker. Looks like an intellectual but is a combatant. Fights with fists and kicks. Shows a kind face if there is no hostility, but does not lower his guard upon first meeting. Once close, he becomes a bit of a meddler and a fun person to be around.
