"Mifune vs. Hanzō" (ミフネVS半蔵, Mifune vs Hanzō) is episode 272 of the Naruto: Shippūden anime.
As the Surprise Attack Division attempt to retreat to the rendezvous point, they are chased by reinforcements of the Akatsuki's own Surprise Attack and Diversion Platoon. Amongst their members are Hanzō of the Salamander who summons his salamander and orders it to attack. The salamander then unleashes a cloud of poison from its mouth that renders the division paralysed. However, Mifune and his division soon arrives and deflects the would-be devastating blow. Conversing about the past and the paths they had chosen to walk, as the two traded blows, Hanzō commands his salamander to come from underground where he had told it to hide. Swallowing Mifune whole, the shinobi prematurely claims victory before the head of his summon is cleaved open and Mifune re-emerges. Moving in for a final blow, Mifune is able to break Hanzō's sickle and respirator. Finally remembering his encounter with Mifune in life, Hanzō moves towards his broken kusarigama and using the blade commits seppuku telling Mifune that he entrusts him with his conviction. This act cuts the poisonous sac that had been placed in Hanzō's body when he was a child, and causes the poison to leak out and evaporate. Shocking Kabuto Yakushi, Hanzō's body ceases to respond to his orders and the legendary shinobi is soon bound and sealed.
