Asou to Seki

Asou Takeru is a student of Seidou High and a left fielder of Seidou's baseball team.


Asou is a lean-built teenager of average height. His black hair is swept upwards from the face and short around the sides and back. He has a stoic face and brown eyes. He shaved his hair for a buzz cut before the Summer Tournament Final vs. Inajitsu.


Asou isn't the type to take the initiative and he doesn't stand out much, but he sulks if others don't pay attention to him. Asou tends to overestimate himself and it's hard for him to realize and accept that he isn’t among the best back in his 2nd year. He is a hard worker, but is always on the fringe, either as the final batter or just misses out on the team. By his 3rd year, he realized he should stop acting cool in front of people as it makes he looks lame instead and that it is time for him to start walk the walk and not just talk the talk. He is on bad terms with Zono as the later is outspoken and is willing to help out his teammates, things that Asou himself also wants to do but cannot take the initiative steps.


Seki Naomichi[]

They are the same age and were in the same class during their second year. They appear to be good friends because they are always seen together.

Murase Nagisa (Ex Girlfriend)

A third year girl from the tennis club. Asou confessed to her before the Ichidai game and she accepted his confession. They dated for only 3 days. After the match against Ichdai, Murase Nagisa decides to end her relationship with Asou.


He has a strong shoulder and fast legs. His teammates have praised his ability to fire the ball quickly back into the infield, preventing runners from taking extra bases. He is said to be the fielder with the quickest ball pickup and throwing motion in Seidou.

Asou is a calculative batter. He is capable of laying off pitches to work the count in his advantage and is capable of producing long hits. However, his hits are often caught by the opponents' fine plays or turn into sacrificial RBI and often does not receive enough recognition for his contribution because of it.
