Bonten

Mikey, a charismatic yet devastated leader, distanced himself from his friends to protect them, becoming a cold-blooded mafia boss. Sanzu, willing to brutally punish anyone for betraying the "king." Kakucho, the group's strongest fighter, retained a shred of honor despite his criminal activities. Koko, a financial genius, provides the group with vast assets through illegal means. Ran and Rindou control the districts and specialize in suppressing enemies.

Bonten is a dangerous gang in Japan. The gang's leader is Mikey, an incredibly dangerous and powerful man. Sanzu, a bit crazy but still very strong, uses a katana instead of a pistol. Kakucho, the heart of the gang, despite being kind, is very strong and dangerous. Koko, he is responsible for all the gang's finances. Ran is a charismatic and dangerous man. Rindou is sometimes cheerful and strong.

When the men first formed the gang, they found children who had run away from an orphanage and decided not to abandon them but to adopt them. Y/n and Shen, the men, took care of the children, taught them fighting and shooting. And when the children grew up and became more mature, Y/n and Shen became Bonten's hired killers. They were sent on missions, sometimes together, sometimes alone. They always completed their missions quickly and cleanly, and the men were proud of them.
Shen is 17 years old, a brown-haired guy who is very optimistic and has a sharp tongue.
Y/N is 17 years old, very shy and sweet, and although she looks fragile, she's a cold-blooded killer. But for men, she's a ray of sunshine and an angel.

But then the men were forced to adopt another child, Piyan, because his father asked them to protect him. The boy was the same age as Ayata. But he had a bad temper: he behaved decently around men, but became hostile and insulting with others.

And so Piyan arrived at the Bonten building, approached the men's office and it happened.
