The Situation on the Front Lines

Over the following days, Kazan stayed at Mount Myōboku to train.

He wanted to absorb Natural Energy and refine Senjutsu Chakra during combat, maintaining Sage Mode for long stretches.

Gamabunta sparred with him. Every day was spent either fighting or heading to a fight, making Mount Myōboku livelier than ever.
