Professional wrestler Yamamoto Shingo returned to Japan from a 5 year training trip in the US and Mexico, only to be greeted by his now defunct wrestling company: Yamato. He's come to find out that as soon as the president of the company passed away, the rival wrestling group Imperial Japan Pro Wrestling (IJPW) took down Yamato. Shingo is forced to seek revenge for Yamato by challenging the president of IJPW. One thing led to another, and now Shingo has been half-forced into working under IJPW as the new wrestler from Brazil: Agnes Mask.
