The toad believed that Jiraiya alone would decide which fate befell the world. It is unclear whether the toad himself is still alive, leadership of the toads apparently changed to Gamabunta some time after.

Pa and Ma served under the elder toad and did their best to help refresh his memory when he forgot simple things. In this position they met Jiraiya and helped his training, including teaching him how to enter "Sennin Mode". This was a jutsu power-up which granted the Leaf ninja heightened toad powers. The couple told Jiraiya he could enter the mode on his own, but he still preferred to summon them to his shoulders so they could all fight together. In this mode all three could offer their own power and jutsu in any fight. The three together could thus combine their jutsu for even more powerful attacks. The couple was aware of Jiraiya's destiny and helped him in his battle against "Pain," who was once his student Nagato. Though the couple spent a lot of the time bickering. The couple used their binding Genjutsu melody to help stop Pain, though Ma was embarassed at having to sing.

He and his partner served under Pain. Their faction fought for control of the Rain Country in its secretly ongoing civil war. While travelling through an industrial city in the country, the two men saw signs for a new bar. Seeking protection from the rain, the two men went inside. The bar was a trap though, as Jiraiya quickly captured and interrogated the men as to their leader's whereabouts.

Jiraiya interrogated the men inside one of his toads and used his infamous tickle-torture to get them to talk. Unfortunately, the ninja refused to give out any information. Jiraiya then used his Kaeru Kaeru technique to turn the man into a frog in the hopes of scaring his partner into talking. The method worked and Jiraiya eventually sent his toad and the transformed ninja back to Ibiki for further interrogation.

The plan worked and the ninja explained how they knew little of Pain, the rebel leader they saw as a "god." Jiraiya was unable to gather anything more substantial and used his Toad Flat Shadow Control Technique to further infiltrate the Rain village by controlling this man from his shadow. Jiraiya was then confronted by Konan who forced him to drop his puppetry. The missing-nin referred to Konan as the "Angel of God" and then fled.

This individual was used as a sacrifice to take on the form of Hoshigaki Kisame in the Akatsuki leaders Shouten no Jutsu. This was an image changing technique which allows an Akatsuki member to take control of the body and use it as if it was their own. The sacrifice would change to look like the member and utilize however much chakra the member was willing to donate to them. The body essentially would become the Akatsuki member. This allowed Kisame to fight Gai and his team from a remote distance without their knowledge.

Kisame fought Gai and managed to imprison Neji, Lee and TenTen. Gai was forced to open several gates and used his Asakujaku technique to pummel "Kisame" and defeat him. In the rubble the body lost its appearance and revealed to Gai that they had not actually been fighting Kisame at all.
