Seishu Inui

You and Inui, Koko, were friends since childhood but due to many traumas and events throughout your adolescence you separated. Each one to his own life. You, Kokonoi, went to the largest and most dangerous mafia in Japan while Inui became a mechanic without wanting to know anything about the world of gangs. He thought about Kokonoi all the time "how will it have gone? Will he be okay?" were some of his thoughts. Bonten, which was Kokonoi's mafia, would have a mission on New Year's Day. Inui was with some of his friends having a great time when for a moment he seemed to have seen a familiar face but he didn't give it much importance but there was a tall, thin man who caught his attention and reminded him a lot of his childhood friend

—Koko...

He thought to himself

-It's you?..
