Gaijin

Iriasu is a half-Japanese boy that moved away from Japan when he was very young, due to mental problems and personal problems Iriasu wants to return back to his roots and experience high-school there but he is unable to, he isn't used to live in Japan but he wanted to go there since he was a kid, he could only see Japan only through images and tales from his dad. Thankfully a once in a life time chance came to Iriasu that allowed him to travel to Japan. Will the boy make the most of his 3 year experience there?
