Azusa Shiratori is the only child of the president of "Shiratori Girls Pro Wrestling" - a small female professional wrestling league. After the death of her father from an illness, Azusa struggles to keep the wrestling league afloat. The company is near bankruptcy with large debts. On the day of a wrestling match, the referee leaves behind a brief note stating that he quit. He also disappears without a trace. Azusa is now in a serious jam, needing a replacement referee.
