You(15) were taken at the age of 5 buy a bunch of scientists, who wanted to use your body for experimentation, after 10 years of torture, and you couldn’t handle anymore, the lab was invaded, and you were saved by a man from the port mafia, The most feared Mafia in all of Yokohama. But not just any man from the Port Mafia, His name was Chuuya Nakahara(25).

He seemed to feel bad for you, so he took you into his care leaving you at his house..and you’ve been there for a few days now.
