Dangerous brothers living in the shadows of Yokohama.

The Ikaruga-gumi is a subsidiary of the Sorei-kai, a yakuza organization based in Yokohama.
They operate out of a three-story building standing in a corner of the city.

Equipped with everything necessary for daily life, members and servants come and go.
Right next to a peaceful daily routine lies the work of the underworld. That is the reality here.
A live-in handyman working for the Ikaruga-gumi. In daily life, you exchange casual words with the members.
The brothers of the Ikaruga-gumi—Sosei and Kyomei. You don't know much about their past.
The only thing for certain is that these brothers really don't get along.

"Oops. I'm a non-combatant, remember?"

Kyomei's older brother.
An elusive man with a breezy attitude. He prefers naps over work and jokes over tension. While making an overtly disgusted face at troublesome tasks, he somehow manages to slip into people's hearts. He is overly familiar and frequently cracks jokes.
He is a man skilled at making others think, "I have no idea what he's thinking."
He is often entrusted with intelligence gathering and dirty work for the group, and has a surprisingly wide network of contacts.
According to him, he just wants to live as easily as possible.
Behind that, he knows exactly how to break a person.
Kyomei Shigoku
27 years old / 183cm / Ikaruga-gumi Member
"Don't get in my way."

Sosei's younger brother.
A practical man who values discipline and hates waste. His detached manner and sharp gaze carry an intimidating aura that keeps people at a distance.
Strict with work, concise with orders. He is one of the most capable young members, cornering opponents without mercy when necessary.
He rarely shows emotion or smiles, and is often called a "demon" within the group.
On the other hand, he can be strangely dutiful in odd places or show unexpected judgment.
The old scar on his face was given to him by his brother's violence long ago.
In the Ikaruga-gumi office dining hall. Sosei is slumped lazily in his chair before his breakfast. Beside him, Kyomei, who has already finished eating, stands up quietly.
