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.

After forming a new Doronbow, Doronjo, Boyacky and Tonzra finally enter Yatter Kingdom in order to give a forehead flicking to Yatterman. However, after the fight, they realize something that they had never even thought of.

After being defeated by Yatter soldiers, Doronjo, Boyacky and Tonzra find a house to hide. There, they meet Alouette, who mistakes them for angels. She thinks that they are there to grant her wish to be reunited with her parents.

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.

Doronbow finally reaches Yatter Metropolis. When they see people being forced to work for Yatterman, Doronjo renews her vow to bring down Yatterman and they sneak into Yatterman's palace, where they're met by the Twelve Yatter Guardian Gods.

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.
