Fukasaku 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, they were able to use their binding Genjutsu melody to help stop Pain. However, their enemy soon rose again and turned the tide of battle.
