I hope that's not a let down, Grimmjow had a certain little girl to go and deal with, so he asked me to cover in, hope thats ok
Kagara responded accordingly, although it felt weird standing in on someones training, but alas, he wasnt going to argue with Grimmjow over this, dude was a savage. Listening to his sensei's explanation about the technique, Kagara merely nodded in agreement to the description before giving it a shot.
Drawing his blade, Kagara channeled the wind chakra into the edge, creating a small swirling vortex of wind chakra that wrapped around the blade. Turning, Kagara brought the blade around to his side, before swinging diagonally across his body. As he did, he released the wind and with a small bit of chakra manipulation, increased its size, causing it to hit the ground and swirling around him, creating a sort of barrier of wind acting as a shield for him blocking the three kunai with ease.
With the next description, Kagara wasn't overly keen to throw his sword as it was, for all intensive purposes, apart of him. Re sheathing the blade swiftly, Kagara fumbled in his pockets for a moment before pulling out a small ink pen. Shrugging to himself, Kagara held the pen to his mouth and began to expelling his wind chakra around the small pen, swirling around the circular sharp, the wind continued to grow off the base, creating a small rapier style weapon. Happy with the appearance, Kagara threw the blade, which, due to its slender sharp, acted like a bullet, piercing the target with ease.
The next technique strayed away from handheld weapons, and in such, Kagara shifted his positions to suit using jutsu instead of weapons. Listening once more, Kagara nodded and began channeling his wind chakra into his mouth before expelling from his mouth. To create the tornado, Kagara blew the stream directly at the ground before moving his head upwards, as he moved his head up, he turned his mouth slightly each time creating a largeish twisted in front of him which would go and clean up a tree.
Moving back to weapons, Kagara re drew his katana and shifted his body once more to suit. Listening again, this one felt more simple. Channeling his fuuton chakra into his blade, Kagara simply repeated his earlier swing, except this time, the chakra stayed in the form of the blade, launching the arc into the tree slicing it clean in hard due to the sharpness and force from the sword swing. Hearing his sensei's question, Kagara straightened up before speaking
Well...i'm not sure, i don't generally plan ahead. I guess, from the top of my head, it would be a good technique to channel into youre blade while its sheathed, to hide the chakra presence. If your opponent came close, you could use a pseudo Iaido to block an incoming strike while releasing the blade of wind around your opponents weapon to cut them in half?
