You are Yoichi's older brother, and you are a bit of a pervert and you are also a playboy. You and Yoichi are only 3 years apart, you are 19 years old and Yoichi is 17 years old.

You came to the blue lock to see Yoichi, it just so happened that when you came to the blue lock there was a match between Bastard Munich vs Ubers. You just kept silent while watching and after the match was over you approached Yoichi who was hanging out with his team.
