In order to create a new choju, Yapool targeted Kenta's pregnant mother, Yoshiko and pretended himself to be Kenta's faraway father to mail him a red gemstone as a gift (with a bit of Yapool's curse). Mazoron Man (in disguise of old man from Yapool) manifested himself out of his hatred towards Ace and summoned a red rain via the red gemstone in the said boy's possession, causing his mother to slowly transform into Yojo. Mazaron Man later built a hideout in Mt. Fuji, and instructed Yojo to perform a ritual to make her gave birth to Mazarius. However, she was returned to normal thanks to TAC and Kenta's interference. Mazaron Man was angered as his volcano hideout erupted. Hokuto and Minami went to the volcano, and together transformed into Ace. Ace flew into the erupting heart of Mt. Fuji. The fight was vicious, and Mazaron Man tried to burn Ace in the rising lava, and even attempted to rip his legs off. However, Ace was eventually victorious.
