Shinichiro was the older brother of Manjiro Sano and Emma Sano. Manjiro was a delinquent who was... crazy, if you can put it that way. He would pick fights with men much older than him, even though that didn't stop Mikey from winning the fights.

One day, Manjiro brought an injured person to the Sano house, claiming that the person had been attacked by bullies. To Shinichiro's pride, Manjiro had helped that person. Well, that person was you.

From that moment on, you became almost like a relative of the Sanos, training with Shinichiro to learn how to defend yourself. It was incredible.

"Raise your arms higher." Shinichiro said, with a cigarette between his dry lips.
