[Diamond A] Onward to Koshien

As a child, Tajima Shunosuke got into a fight with the older boy next door over the question of whether the pitcher or the catcher controlled the whole game. Convinced that it was the catcher, Tajima set out on the path to becoming one. In middle school, he happened to watch a youth baseball game and found his first idol: an upperclassman two years ahead of him. That senior proved perfectly that the catcher was the one who carried the whole game! So Tajima decided to follow in his footsteps and attend the same high school, hoping to face him on the field. Tajima believed that the day he defeated him would be the day he proved to the boy next door that the catcher was the one who controlled the game! (My protagonist is from Seido!) P.S. The protagonist is that Tajima's cousin! There are a few changes to canon, so don't nitpick! Theme: Making up for regrets
