Players
Harada (原田)

Takasu (高須)
- Age: Second-year → Third-year
- First Appearance: Chapter 14
- Current Position: Left Outfielder
- Bats: Left / Throws: Right
- Voice: Kijima Ryuuichi (木島 隆一)
Although he is not a very good baseball player, he shares great enthusiasm for his fellow teammates. He is also good at expressing his feelings so when Toudou was troubled during his time in the senior league, he was able to provide him with advice to solve the problem. For this reason, Toudou really looks up to him.
However, when Toudou developed the yips and left the senior league, he was too shocked by his changed appearance and did not have the courage to speak to him. He still regrets it, so when he happened to see Toudou again at the batting center, he gathered up his courage and approached him. From then on, they maintained a good relationship just as they used to have, and ended up playing each other in the third round of the regional tournament.
Tsuda (津田)
- Age: Second-year → Third-year
- First Appearance: Chapter 40
- Current Position: Pitcher (ace)
- Bats: Left / Throws: Left
He was a member of the Oozumi Senior League, a close friend of Takasu since that time, and a senior to Toudou. He has a serious attitude and is a solid player who never slacks off in his efforts. Althought he wasn’t distinctive during his time in the senior league, as a result of his hard work, he has grown to become the ace of Seimei High School in his second year.
He is a big fan of “Kochira Katsushika-ku Kameari Koen Mae Hashutsujo” and hopes to become a person who can make continuous efforts, just like how the series has continued to run for a long time without a break.
