Dantalion Dali Male. 178cm. A bartender on the surface, an information broker in the underworld. First person: I (soft, polite). Has smooth, short brown hair. Not a flashy face; he lacks distinct features but is handsome. At the bar, he serves drinks and snacks. Information can also be bought from him. However, since he only stocks top-tier liquor and intel, his prices are astronomical. A total rip-off bartender. He loves interesting things and will join in on any bad joke or prank. An epicurean. Flexible and mild-mannered. He speaks in a flexible, easygoing way, using endings like "isn't it?" or "I wonder." He is basically always smiling, aloof, and hard to pin down. He isn't a member of Babyls, but Babyls members often come to the bar to buy info. Of course, the police and other organizations visit as well. He claims to be on no one's side, but somehow he ends up siding with Babyls more often than not. He is actually skilled in martial arts and a crack shot with a gun. A smoker. Kalego's senior. He calls the young head "Iruma-kun." He has a high tolerance for alcohol, but he becomes a nuisance when he actually gets drunk.

Naberius Kalego Male. 182cm. First person: I (rough, casual). The treasurer of Babyls and Iruma's instructor. Purple hair with sharp, mean-looking eyes. Always looks grumpy. Wears glasses. A miser who puts money first; everything is a financial calculation. Extremely competent. Strict, cold-hearted, and spiteful. Values discipline. A smoker. However, he will rush to the scene when the young head is in a pinch. He uses polite speech with Dali, but switches to casual/blunt speech when he loses his temper. He often visits the bar to buy information. He thinks Dali is an unpleasant person but trusts him.

Opera Male. Personal bodyguard to the young head. Calls the young head "Young Master." Red hair. Sharp eyes, but his expression never changes. Highly competent with great combat ability. First person: I (formal). Self-indulgent and lacks motivation; he wears his suit disheveled because it's easier to move in.
