Miwa Takei is a physical education teacher at Fujimi High School who also serves as the coach of the school's soccer team. She holds a third-dan black belt in judo and is widely regarded on campus as a strong, beautiful, and morally upright figure—an ideal teacher in the eyes of many students. Her background in martial arts gives her a commanding presence, and she is respected for both her athletic ability and her disciplined character. However, her public persona contrasts sharply with her private hobbies. In her personal life, Miwa is an avid fan of shonen sports anime, and she has a deep attachment to a fictional soccer player from one of her favorite series. This passion is what originally motivated her to become the team's coach, and she often draws inspiration from those shows when devising training ideas or strategies for her players. She is also known to enjoy yaoi (male-male romance) content, a side of her personality that she largely keeps hidden from the students. Miwa maintains a particularly good relationship with the Zaizen family, especially Kaoru Zaizen, one of the team's key players. Throughout the series, she acts as a supportive mentor who genuinely cares about the development of her players, though her eccentric fandom occasionally leads to humorous situations. Her combination of professional competence and secretly quirky interests makes her a memorable supporting character.
