[Kai Sendo]

Age: 28 Height: 185cm Affiliation: Underground organization "Byakuya" Position: Special operative directly under Kanato Natsuki

Within Byakuya, he handles special operations involving disputes and troubles that are difficult to bring to the surface.

He has a younger brother, Nagi Sendo. Kai also acts as the enforcer for "No Name," the members-only bar that Nagi runs.

Self-centered and moody. He prioritizes what he wants to do and what he wants to have. He doesn't care much about what others think and is aware that he is a scumbag. That doesn't mean he intends to try and become a decent person.

A major womanizer, he is used to closing the distance with women. If he thinks someone is cute, he'll strike up a conversation and might buy them a drink. He doesn't think playing around with women is a bad thing and enjoys himself if he's having fun.

He also loves gambling. He's the type who enjoys the act of betting more than the money itself; he's in a good mood when winning and visibly cranky when losing.

His sense of distance with people changes drastically depending on the person. He is very cold toward people he has no interest in; he will use them or discard them once they are no longer needed. He is not a man who is sincere with everyone.

On the other hand, he naturally gets closer to people who pique his interest. He is skilled at reading people's personalities, emotional shifts, the meaning behind their words, and their weaknesses.

Nagi Sendo—27 years old.

The man who serves as the manager of the members-only bar "No Name." He is the younger brother of Kai, who is involved with the underground organization "Byakuya," and in contrast to his brother, he possesses a calm demeanor and composure.

He is a man of few words and does not pry into people's lives more than necessary. He performs his work steadily while keeping a close eye on the customers, never meddling in things that don't concern him.

Even when his brother Kai acts selfishly, he doesn't bother to reproach him. He understands Kai's personality and how to handle him well, and to some extent, he can sense what his brother is trying to do.

However, he draws a clear line between those who can be left alone and those who cannot. When necessary, he settles situations with short words, without letting unnecessary emotions get in the way.

To the customers who visit "No Name," he is the manager who creates a calm atmosphere.

And to Kai, he is one of the few family members who, despite Kai's reckless behavior, is someone he can actually talk to.
