Haruichi to his teammates

Kominato Haruichi is a student of Seidou High School and the younger brother of Kominato Ryousuke. He is the roommate of Maezono Kenta and freshman, Mogami Takeshi. He plays second baseman and is one-half of the baseball team's Keystone Duo. He is also a close friend of Sawamura Eijun and Furuya Satoru.


Haruichi is a short, small framed teen with pink hair. His eyes are hidden by his bangs, only appearing during dramatic moments such as batting.

He is considered to be cute by his female classmates as his appearance being likened to a girl. 

In Act II in the manga, Haruichi cut his front bangs after the Komadai match and his eyes are now easily seen.


Born in the Kanagawa Prefecture, Haruichi is a very calm and quiet person, often acting as the tsukkomi to Sawamura's boke. He is shy by nature but has a habit of saying things bluntly and often praises either Furuya Satoru or Sawamura, causing the two to compete against each other frequently.

He plays reserve in the first-string team and occasionally feels envious of Sawamura and Furuya for being able to play in a match. He is rather small in comparison to the other boys and it has been noted that he looks a bit like a girl. He is easily embarrassed, especially when praised.

Haruichi's relationship with his brother is slightly strained because they play the same position, but he still admires the elder to no end. Though reserved, he is highly ambitious and aims to take his brother’s position. When he was a child, their relationship was closer as Kominato Ryōsuke often protects Haruichi from bullies.


I've been using a wooden bat at practice too so I know for a fact that if the ball is off the sweet spot even a little, it just won't fly.
Miyuki about Haruichi..[5]
One of the most unique things about Haruichi is that unlike virtually every high school baseball player, he uses a wooden bat instead of a lighter metallic bat. He thought that in order to catch up to his older brother, he has to use the heavier, more difficult to master wooden bat.[6] Haruichi is a naturally talented, all-rounder baseball player. Kijima Rei once said that his ability in baseball actually exceeds that of his older brother’s, also a talented contact hitter and a second baseman himself. He started out playing as a pinch hitter during the Summer Tournament and was later promoted to 3rd in the batting line-up, becoming one of the three-hole, starting from the second round of the Fall Tournament. He has held on to the position until the Spring Tournament of his 2nd year. After the Spring Tournament, he now bats 2nd in the lineup.

Despite his small stature and frail appearance, he has pinpoint precision while batting the ball. This makes Haruichi a skillful contact hitter, able to hit it as wide and as far as he pleases, and control where the ball lands and the fact that he uses a wooden bat make his skills even more impressive. Also extremely talented at defense, Haruichi is able to catch a ball in the air and throw it while still floating.

He is noted to have sharp baseball senses, able to decide in a split second where to hit the ball, what to watch for, and when to steal. As such, Haruichi is capable of pulling off fine plays that contributed greatly to Seidou High in critical situations. For instance, in the 9th inning of Final of the Fall Tournament, Haruichi pulled off a series of consecutive fine plays that include landing a clean hit on Sanada Shunpei's Shuuto, stealing 2nd base and most significantly, feinting a squeeze to home plate to distract Yakushi High School's fielders allowing Miyuki Kazuya to make it safely to 2nd base with his risky stealing attempt, all happening at 2 outs where one error could have immediately cost Seidou the match.


One of the thing he lacks is stamina, which he works hard on improving. Despite the fact that Haruichi has managed to hit a HR once using a wooden bat, it has been repeatedly mentioned that he may lack power due to his small frame and also because the wooden bat is much heavier than a metal bat. To mitigate this weakness, Coach Ochiai Hiromitsu ordered him to use a metal batin the intrasquad and Semifinal game during the Fall Tournament; however, after unsuccessful attempts in both games, Haruichi later refuses to use a metal bat again and decided to stick to his own style. His weakness resurfaced during the Spring Senbatsu where he was said to have less success in the National-level Tournament. After the loss to Ichidaisan High in the Spring Tournament, Haruichi is determined to improve the speed of his swing to make up for his small stature and has been practicing tee batting from all different types of difficult positions.[7]
