Muscle Girl! (2011)

Ichikawa plays the part of Azusa, the only child of the owner of a small female pro wrestling organization. After her father dies of illness, she has to take over the business, which is already losing money and is on the verge of shutting down. To make things worse, their referee suddenly disappears on the day of one of their shows, leaving behind only a resignation letter. The desperate Azusa then runs into a young Korean man (Lee). She persuades him to serve as a referee just for that day, though she doesn't realize he is actually a popular star in Korea.
