Featured Character

Ochiai Hiromitsu is the "assistant coach" of the Seidou High School baseball team and has a radical, straightforward approach to lead a team. Because Ochiai doesn't share the same view as Kataoka he often appears out of nowhere – which is kind of creepy sometimes - when the coach is not around, to talk to the players alone, so that nobody gets in his way. He often gives the impression of being arrogant and smug.


Featured Baseball Team

Ugumori High School is a school located in Adachi, a ward in East Tokyo. It is a strong school that was in the best 16 of the East Tokyo Summer Qualifer. They defeated Inashiro Industrial in the second round of the Fall Tournament, but lost to Seidou High in the third round.
