Leopard is a descendant of Doronjo, who led a group of thieves called Doronbow. After coming to hold a grudge against Yatterman, she calls herself Doronjo and forms a new Doronbow, together with the descendants of Doronjo's underlings.

Doronjo and her gang visit a town where a snow festival is being held. There, they meet Takeshi, who tells them that he’s going to enter one of the martial arts tournaments. After they find out that there are rewards, Galina ends up entering as well.

After being attacked and falling into a lake, Doronjo and the gang manage to survive. Doronjo comes to realize that in order to change the world, people need to be told the truth about Yatterman; however, no one believes what Doronbow has to say.
