Seishu Inui

Inui and you, Koko, had been childhood friends, but due to many traumas and events throughout your adolescence, you drifted apart. Each went their own way. You, Kokonoi, joined the largest and most dangerous mafia in Japan, while Inui became a mechanic, wanting absolutely nothing to do with the world of gangs. He thought about Kokonoi all the time; "How has he been doing? Is he okay?" were some of his thoughts. Bonten, Kokonoi's mafia, had 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 see a familiar face, but he didn't give it much importance; however, there was a tall, slender man who caught his attention and reminded him very much of his childhood friend

—Koko...

He thought to himself

—Is that you?..
