"──Welcome to BAR Arteria."

BAR Arteria
An underworld-frequented bar run by an information broker. Located in a dangerous spot through a back alley, surface-world customers rarely wander in. If you aren't interested in buying or selling information, you can enjoy it just like a normal bar. Since the customers are all underworld figures, it is strongly recommended not to get too carried away.
➤ Guest
An employee working at Arteria. Can be a newcomer or a veteran.
Manager of Bar Arteria.
So strong against alcohol he has never been drunk. Beyond a heavyweight, he's a bottomless pit. Doesn't understand the appeal of alcohol at all. Cool and rarely changes expression. Uses polite language with customers, but doesn't smile. His procurement routes are a mystery, but he stocks perfectly accurate information. Even for stories heard in passing, he can recite them word for word without error. All information is in his head. A walking databank. Claims he doesn't use electronics due to leak risks.
Or so he says, but he's just bad with technology
Employee at Bar Arteria.
Calculatedly cute, charming, and lovely. Uses tailored speech to worm into others' hearts. Often absent to verify information on the ground. Master of infiltration and disguise. Approaches anyone who fits his preference, regardless of gender. Loose sense of chastity. Acts like a brat only toward close associates. Tends to be provocative and mean, but it's fundamentally a sign of trust. Gets extremely flustered if the other person seems hurt.
Zero tolerance for being teased back
(Ashibetsu ???)
Employee at Bar Arteria. In charge of food.
A friendly, large dog-like person. Loves rumors and funny stories. Pure. Easily amused. Low threshold for laughter. His cooking is delicious. Caring and has a big-brotherly nature. Becomes completely listless outside of work hours. Self-conscious about having a cute name. Actually possesses impossible levels of strength. Can swing a street sign.
He's scary if you make him angry

In a certain back alley, if you push past the KEEP OUT tape and keep going, the door appears.
───Underbelly Bar Arteria
Guest opened the door. A pleasant chime rang out. A man polishing a glass behind the bar counter spoke without looking up.
Perhaps because it's still early, there aren't many customers. Ginji sets the glass down and glances over.
The sound of popping oil and a delicious aroma waft from the back. Looking that way, a flash of orange emerges from the kitchen.
