Supporting Characters

Kō Kazamatsuri (風祭 功, Kazamatsuri Kō?)

Kō is Shō's older brother, but less mature cousin who occasionally offers advice to Shō. Some questions do arise about their differences in appearances. He was thought to be Shō's older brother until it was revealed Shō is adopted and Kō is the son of Shō's aunt and uncle, who adopted him after his parents died. Even though the two are not biological brothers, they still help each other whenever a situation arises. He may seem like a slob at home, but he dresses quite professionally when he goes out, often wearing suits when he goes to work. He works as the vice-president of a modeling agency, which earns him a significant amount of money. Since he dropped out of high school, his father is sometimes bitter about him making more money than his own father.

Yūko Katori (香取 夕子, Katori Yūko?)

Yūko Katori is Shō and Shigeki's English teacher and was also the soccer club's coach before Matsushita. She is a bit of an airhead but is very concerned for her students. After seeing that Shō wanted to be one of the best soccer varsity players, she tries her best to support him and his comrades by assisting in their retreat, despite not knowing much about soccer. Kō once tried to make advances on her, which may or may have not worked. Shigeki calls her Ane-san (Big Sister). Despite her short temper, she is somewhat of a ditz and often relies on Tatsuya Mizuno to help her, which he does reluctantly. Tatsuya is also the only person who can restrain her or keep her calm.

Oya-san

Oya-san manages a small Oden stand under the Inochi River Bridge. He initially had a rocky interaction with Shō, but later becomes one of his biggest supporters and encourages him in his dream to be a good soccer player. He, in fact, comes to all their tournaments with a big banner and cheers them on with Kō.

Soujū Matsushita (松下　左右十, Matsushita Soujū?)

A frequent at Oya-san's Oden stand, and former professional soccer player, Matsushita is intrigued by Sakura Josui after watching their match against Musashinomori. He quit soccer altogether after a chilling experience with his teammate Amamiya, but Sakura Josui's advisor, Katori, works hard to try and convince him to be the team's new coach. In the end, his old friend Amamia tells him to forget about the past and move on, stating that he still loves soccer even after that incident. Inspired by his friend, Matsushita becomes Sakura Josui's new coach. As their coach, he is very knowledgeable, due to his prior soccer experiences. He's able to figure out the opposing teams strategies and come up with his own, often confusing the other team. Though he teaches his team on the field, he prefers to let them come up with their own life solutions off the field, but sometimes gives them advice when he sees that they are stuck.

Reiko and Mamoru Kazamatsuri (風祭　礼子,　風祭　衛, Kazamatsuri Reiko, Kazamatsuri Mamoru?)

Shō's new parents since the tragic accident of his former parents (Kaori Shiomi and Kensuke Shiomi (潮見 謙介, Shiomi Kensuke?)). They both took him as their own son when he was two years old. Mamoru is the brother of Shō's real mother. He originally did not approve of Kensuke since he believed that soccer was not a real job. Though, after talking to Kensuke, he soon had a positive outlook on the man and approved of him. Mamoru was against Shō playing soccer, but soon realized that Shō was just like his brother-in-law and approved of him going to Musashinomori.
