==Personality==
Koichi is very attached to his older siblings.
Koichi is very social and makes friends easily. However, his forward personality is sometimes misinterpreted.
Koichi knows how to keep his cool when the game is going against his team, but that doesn't stop him from getting riled up.
==Abilities==
Koichi is a baseball player and can play two different positions when the situation calls for it: pitcher and shortstop, although he primarily plays pitcher. Currently he plays for the Enoshima Sea Turtles (江ノ島ウミガメ/Enoshima Umigame), a little league baseball team. 
Koichi throws right-handed. As a pitcher, Koichi is a sidewinder (meaning he throws sidearm) and has an excellent throwing arm despite his age, pitching balls balls between 87mph (140km/h) on average and of nearly 92mph (148km/h) at a top speed, though he constantly strives to pitch faster. 
Koichi's very perceptive on the mound, always carefully observing his surroundings before throwing. Usually he follows the catcher's lead, but will to shake him off if the situation calls for it. His perception also allows him to know when it's appropriate to let batters hit in order to get outs with double or triple plays. His good arm also allows him to pickoff runners, provided that errors aren't made, whether by himself or the fielders. From the mound he is also able to calmly analyze the batter by watching their practice swings (assuming the opponent does any), allowing him to adjust his pitching pattern as need be. His good memory of batter-quirks allows him to adjust strategy when the lineup starts over. 
His best, and usual, balls are fastballs, and one of his ultimate goals is to be able to throw a gyroball. His best breaking balls are curve and screwballs. He has been trying to master the forkball as his changeup, but so far hasn't thrown it successfully in a game. He also practices sliders and other forms of pitches, although he tends to struggle with them. 
When he's not on the mound or on the bench, Koichi also plays shortstop. As a fielder in that position, he has excellent judgement on where the ball is going to fly once hit, allowing him to instruct fellow players on where to move to catch the ball. He is also fast enough to catch the ball himself when it hasn't flown too far.
Like his pitching, Koichi bats right-handed. As a batter, he has good eyes: with excellent dynamic vision, depth perception and momentary vision, he's able to anticipate where most balls are going to go; yet he's not incapable of being tricked and struck out.
His batting arm is strong as well, and he's capable of hitting to outfield most of the time, whether it's fly-balls, low liners or grounders. He is capable of hitting home runs, but it doesn't happen often for him. Koichi can bunt as well, but he's not very proficient in this area and his bunts are usually picked up within seconds. Pop-ups are a sometimes occurrence for Koichi as well.
As a baserunner, Koichi is very fast. Having inherited natural speed from his parents, he's capable of running double or triple (to second or third base in one run) if his hit is good enough to allow it. He is also observant enough of his surroundings that he is able to steal bases, provided he isn't picked off from going too far too soon (which tends to happen 20% of the time). It's for these reasons that Koichi normally bats first or second in the lineup.
However, despite all his ability, he's not incapable of being fooled or slipping up; and, as a pitcher, he sometimes tends to struggle with control, especially when his stamina is spent.
