Takatsu Hiroomi is a second year student at Seidou High School.


Takatsu is a well-built, tall player with reddish-brown hair and gray eyes (in the anime). He always seems to have an intense expression on his face.


Takatsu has an intense and competitive personality. He dislikes the fact that there are some freshmen, namely Yuuki Masashi and Yui Kaoru, who were promoted to the first string before the second and third years on the 2nd string who have been training hard themselves. Oota said that Takatsu has always been a player with talent; however, he couldn't make an impact since he was physically weak in his first year. After building up his body during the winter season, he has started to become quite a notable player.[1]

Contrary to his regular serious look, Takatsu also seems to have a softer side around his group of friends, which mostly consists of non-regular members. He showed embarrassment when being teased by them, and expressed his desire to give his all in the first string for the sake of his friends that couldn't make it.

Act I[]

Takatsu was briefly mentioned by Natsukawa Yui and Umemoto Sachiko when they were discussing talented players of the new first years. However, he never makes an appearance, other than in the intrasquad game where he was seen with a towel over his head.

Act II[]

Takatsu and numerous other 2nd string members were seen doing batting practice on the back alley. Takatsu said it was the only place where they could do extra practice, since all the gyms and practice rooms were filled with regular members.

Takatsu and the upperclassmen participated in the intrasquad game and were poised to demonstrate their determination and hard work to the coaches, as well as sending the first years the message that they were not intending to give the freshmen any promotion opportunities. Takatsu played as the cleanup hitter and displayed a stellar batting performance, getting three hits and four RBIs.[2] His success earned him a promotion to the first string.

After the game, Kanemaru showed up to congratulate Takatsu. However, despite Kanemaru's sincere intentions, Takatsu didn't take his words as a compliment, instead saying that Kanemaru doesn't have right to look down on him just because Kanemaru managed to qualify to the first string first. He then abruptly walked away.

On the following day, Takatsu was teased by his friends for looking dreamy after becoming a first string member. Oka congratulates Takatsu on finally gaining the official right to join the regulars in the training areas. Takatsu said he'll run rampant in there for them to see.

Originally playing as shortstop, Takatsu has later asked Kataoka for permission to practice as a third baseman as well so he can open himself up to more opportunity, something that Kanemaru disagrees with, saying he may fail if he gets too greedy.
