Episode Title:
The Mightiest Transformation! The Ryōzanpaku Rhythm!.
Episode Description:
Kenichi is unable to avoid Odin's Gungnir attack and takes several heavy strikes. Odin recalls how, as a child, he realised Kenichi was not as dedicated to learning martial arts as he was and after Kenichi's betrayal bought himself a Yin-yang badge and trained for 10 years to defeat Kenichi and prove he was weak by swapping his badge for Kenichi's. Eventually he witnessed Sage fist mercilessly kill two assassins and became his disciple to attain power. Kenichi allows himself to be struck several times to get in close and use the powerful punch he used to defeat Siegfried, though Odin still manages to block it. Realising that Odin can predict his every move with his Inner Eye Kenichi instead models his movements after all of his masters, completely changing the rhythm of his movements so that even Odin's Inner Eye can't predict where he will strike. By copying the movements of Apachai, Sakaki, Kensei, and Shigure Kenichi is able to land multiple powerful strikes on Odin. This greatly entertains the watching masters who are proud their disciple has improved to such a degree as to copy their moves. By finally imitating Akisame Kenichi performs a Judo throw but Odin is accidentally wounded when he lands on broken metal. Odin, furious that Kenichi still does not remember how he betrayed him as a child uses an extremely dangerous technique, by combining both the Dou and Sei energies in his body he becomes monstrously powerful.
