He could not fight him head-on!
From Jiraiya's brief attack, he knew that if he fought Jiraiya in this state, he might not die... but the best possible outcome would be being sealed away!
But—
He had no desire to be sealed!
He was also rather frustrated. Were ninjas these days all this strong? He had thought that with an Impure World Reincarnation body, he could contend with anyone. Even against the First Hokage, he believed he could put up a fight.

Jiraiya spoke as an enormous Rasengan formed in his palm, radiating terrifying energy!

He rapidly formed hand seals. Terrifying energy surged through his entire body as he concentrated all of his Chakra into this single ninjutsu!
He wanted to use this fire dragon to block Jiraiya's attack!
But—
He had still underestimated the giant Rasengan. This Rasengan
