Muscle Girl!

After the death of her father from an illness, Azusa struggles to keep the wrestling league afloat.

On the day of a wrestling match, the referee leaves behind a brief note stating that he quit.

Azusa then stumbles across a Korean guy (Lee Hong-gi) she meets on the street.

Unbeknown to Azusa, the man is also a popular star in South Korea.

In order to keep "Shiratori Girls Pro Wrestling" afloat, they then join forces to go up against a rival pro-wrestling organization.
