"Excuse you? I'm the most confident in my abilities, the confidentest, there's no one in Noragakure as rightfully confident as Fukumatsu Azuku." She stood tall at her full height, which was, as Kichi had come to know by now, not at all that impressive. "Well, it could be a combination of chakra output and precise control... Admittedly I don't use Shuriken often, though I should probably fix that for the future..." She hummed in thought.

"Gimme a visual demonstration, I'm *Nyat* A mind reader. I wanna see exactly where the mess up is so I can jumble together some advice that may or may not make sense." When compared to other aficionados, Azuku's ability to articulate the use of jutsu was... Not the best it seemed, though at least she seemed eager enough to help. "I'm gonna guess it has to do with adjusting from gentle manipulation to harsh force, but I'd like to see to be sure."

"Alright. Here." He gestures at a pair of dummies nearby - other than them of course before four kunai slip into his fingers. It's not immediately clear where he got them from, honestly, but he layers them with chakra before tossing one pair after the other at the two dummies. There's a quartet of sharp '*Shlick' as the wind covered blades slice neatly through the cloth coat over the wood beneath - but they don't quite go through. 

"There's a technique I've been working on that needs the extra finesse wind gives ya. Can't quite get rid of the hissing sound just yet." Azuku wasn't adept enough with her ears to even catch that, but Kichi can feel the vibrations in the weapons enough to know that things aren't perfect. "Plus — well, should probably be able to slice through a dummy yeah?"

She blinked, tilting her head... She hadn't heard even a peep from the shuriken... But considering what kinda stealth specialist Kichi seemed to be pushing himself towards, Azuku supposed that there was something she was missing that he wasn't. "I'm gonna be honest, when it's... *That* Specific... Maybe it's natural... Air resistance causing that whistle? If you wanna get rid of all sound, there's gonna have to be virtually no resistance... That or some kinda bubble of undisturbed air to allow em to travel..."

She closed her eyes, this was a lot more complicated than simply telling him to be more precise, it required direction as well. "Those are the two best options I can tell ya to go down, there's a few jutsu I can think of from the library that focus on directing shuriken with precision... Maybe use those as a basis? I dunno... Ugh, you really gotta ask the complicated questions..."
Francis
"Alright. I'm not too ready to work on that technique - but I can work on the precision here." Kichi spends the next hour or so workshopping things with Azuku - thankfully it isn't with too much of an air of what is to come, but as he describes the technique he's working on it becomes more and more apparent just what he's making. As Azuku knows Silent Killing, there's a few degrees of separation but. . . This is something far more intense. 

It's an assassination technique - how wonderful! 

Regardless, Kichi leaves with a smiling wave and hop to his step, a new understanding to wind release techniques settling into the back of his mind after a productive training session.
