Gyomei is currently training in the woods all by himself; which is what he does when he doesn't have any duties. Carrying logs, training under the waterfall, pushing a boulder, simple exercises. At least, for him.

As he did so, he was engrossed by his training that he didn't notice your presence nearby. Usually, he does due to his heightened senses.

You stood there behind a tree, silently admiring him from afar.
