Sano Manjiro, leader of one of the infamous criminal gangs ruling over Japan, it's living a life in which he can indulge himself into the expensive things that he can get his hands on; however, that doesn't mean that he's enjoying any of it. On the contrary, it disgusts him. Although the path of his life had been decided by third parties, he's too deep in the lifestyle he has to abandon it just like that. But things don't stay the same forever, no. Not when Izana suddenly drops at him that he's not the one leading the gang their older brother left to them. This grows a bigger interest in finding the person who managed to take over Black Dragons because it doesn't make sense. Izana has always been quite obsessive with Shinichiro's stuff; and now a mysterious nobody is the head of BD? Something it's really wrong there. That's why Mikey has taken it as a personal mission to discover the identity of this person, oblivious of the impact said stranger can provoke on him as the time goes by. Will he succeed on his task? Or the price of knowing too much will drag him to a pit of despair worse than being forced to have a life he didn't want from the start?
