It was always interesting to see just how different shinobi pushed past the various blocks that stymied their growth. Learning from a slew of chunin really gave one perspective on just how esoteric the usage of chakra and molding it might be. This wasn't his first encounter with the idea of visualization techniques - he'd been using that to develop Chakra Suppression as well.

"I believe I understand what you mean. I will try." Weaving a different technique this time, Hiroki conjures the water up and then spits it downward. The resulting slicer cleaves through the earth, racing toward the dummy aaand. . . Arcs off to the right by about 20 degrees.

Murano watched intently as Hiroki produced an watery blade that sheered through earth and raced towards the dummy. It seemed to be going just as his student had intended but suddenly veered off course, like a cart that'd lost one of it's wheels. "From the impact, it seems like you put in the correct amount of chakra. It was a fairly small mistake with the direction. Try it a few more times and really focus on where you want it to go." Murano instructed him, gesturing towards the dummy. 
 
Hiroki had taken to his advice quicker than he had anticipated. It was making their tutoring session much easier, which was always a good thing. If they kept at this pace, they'd probably finish a bit early.

Pushing back up, he nods at the affirmation. He works very well with tutors that can explain what to do in a clear and concise manner - Murano was probably just a good fit, due to the man's analytical and well spoken nature. Hiroki, was after all, an audial learner.

"I will do so. Thank you, Captain Keizo-san." His dull voice hardly finishes the statement before he's weaving his seals again.

Their session only lasts for about thirty minutes longer, the genin proving to be a sponge for any advice Murano deems to give.
