The slightest of smiles was roused at Kojiro's response, but nothing more. It was good, of this he was sure, that the man's outlook was as such. It was open, free, and almost without care for the negative aspects of life, uncaring that it would one day end. It was better that way. Taking in a deep breath and invisibly expanding the patterns of his blade, Zume readied himself even as Kojiro's stance was taken, and his slash executed. The patterns moved to surround him as he
read the technique's name from the man's mind, and simultaneously ran a simulation in his mind in regards to the result of the chakra moulded to execute it. All this in a split second and then the movement patterns manifested, and began to spin, each a oval-shaped blade which met at a point above his head and rotated upon that axis, angled downwards in a slow much like a massive umbrella. Each of the blades was 1.5 meters across and almost 3 meters in length. While there were small spaces between each angled piece of pitch black armor--composed of a mixture of solid and liquid void weaved together so as to create a more resilient structure-- they spun and as such caught air and flung it outwards in a secondary dome around 5 meters in radius, with Zume as the epicenter.
He did not utter the name of a single technique, for it had no name beyond that which was used for the techniques any Tatasuko utilized to manipulate the void's chakra.
"I may have passed your test, but you've only passed one of mine..." he said quietly to himself, smiling despite the man's inability to see the expression.
"...but perhaps you will yet," he chuckled, and moved his arm in position to slash horizontally. As he did so, the movement graceful, his arm taking its time to move, 20 more of the movement patterns became externalized from the blade, 10 which formed more of the ovals, though they waited to enter the physical. The other 10 positioned themselves around the blade at different angles, elongating and being forced into the shape of sharpened, pointed edges by his will as they did so.
Taking in a deep breath, only a brief 7 seconds having passed since he had erected his defense, his eyes focused and he slashed. He could see it all, every atom, react to the motion as if time were slowed. He could choose to see everything like this, so as to react properly to every minute change or aspect of any given action taken by others. As the blade gradually traveled through the air, the oval plats that hadn't been utilized yet joined their brethren even as those that shaped his defense parted for a moment only for the new spaces to be filled by the moving ovals. His defense had expanded, and as it did so did the massive torrent of wind that surrounded him.
Initially the oval-shaped constructs had blocked the blades sent at him, but as they spun and formed the torrent of wind, the wind tore the fragments of dust apart before they ever reached the shield.
The slash however, traveled straight through the field of wind invisibly, the patterns externalized, but not yet physical. As they exited the field of wind they scattered, all 10 of them, opened into wide circular blades, hollow in the center, with the distance between each inner portion being a diameter of 8 meters. However, with no air resistance to yet impede them, the still invisible blades, rapidly moved shrunk, appearing like an invisible gyroscope and Kojiro is in the center.
To give his opponent a chance and to allow them their own kinetic energy, Zume physicalized the bladed rings when they were roughly 5 seconds from fully closing in, and thus cutting Kojiro to ribbons. This allowed for a brief period of time in which he could block, somehow, or escape the enclosing rings.
