What is this Ninjutsu?

Autumn. The weather was turning cool, the leaves were falling, and rain continuously drowned the earth. Perfect for more setups of the way of the ninja. Smiling to himself, Henrex relished in the cool air of fall, leaping into a tree and scoping the area of Karakura Forest, watching its transformation that it would undergo throughout the year. Fall had always been one of his favorite times of the year. Not too hot, not too cold, it always a nice temperature that never seemed to be anything other than just right.

But, there was another reason that he was out here.

Yet another sought to learn ninjutsu. Henrex had a feeling that Soke would be immensely proud of him for spreading the ways of ninjutsu to the modern world. Someone named Sato, a botanist from the Sugiura Kingdom. Eager to receive more students for the way of the ninja, Henrex disappeared from the branch that he sat in, reappearing at the end of his flash step in another, repeating the process over and over again.

Soon, he silently appearing a small distance away from who he assumed to be Sato. Dropping from the canopy and landing on the ground, Henrex approached the Sugiuran from behind.

"Are you Sato?" He asked, walking next to the boy as he scanned them up and down.

Stepping in front of Sato, his head slightly tilted to the side as he saw his fingers.

"You...look cold." He said, taking his haori off and holding it out to them, expecting them to take it. After all, he couldn't just let someone sitting out here, freezing like this.

Whether or not they took the Captain's garb, he wordlessly turned around, drawing his sword and drawing in four symbols and words in a set of circles. Earth, Water, Fire, Wind, and Void. Written with the kanji characters, followed by the English translations, Henrex sheathed his weapon and sat down in front of the circles, cross-legged.

"Why do you want to learn ninjutsu, Sato?" He said. "What do you believe is in ninjutsu that can help you with your goals, aspirations, and wishes?"
