[Kazuo is, most of the time, a showoff, but also just as much of a pragmatic fighter. To win there are no rules, especially against opponents looking to claim your very life. Of course, this entire situation was a bit different and his bigger concern was looking like a dumbass. Emi had a strength far beyond him. Far beyond his current self anyways. At the very moment she took the signal to approach, lines of white light would cover his right hands and forearm up until the upper arm.]
"Purgatorio - Awakening Gauntlet!"
[The light would become an armor exuding a strange energy constantly. The fingers become metallic claws; the palm all the way to the forearm and upper arm would become covered by a black leather-like material. The back of his hand would be covered by metal for extra protection: a manacle-like piece would appear around his wrist from the which a large blade would come out, as long as his arm, providing cover for the rest of the limb, as if having a blade in a reverse grip; finally, four plaques would appear one after another covering the forearm, like gills, subtly moving at the rhythm of his breathing. Appearing in an instant, he would use it to block the initial strike.]
"You're too strong, I had to match you somehow!"
[It was weird to him. Although he resisted the initial impact, and he knew the rest of his body would feel it worse, he still feels a strong pain on his right. Even so, Kazuo kept smiling, the glint in his eyes becoming so clear it was easy to read his mind. It was exciting to him, somehow, how strong Emi was. The second strike he would impact with his fist, then cover again for the third and barely stop the fourth. Each time it hurt like hell, and each time he knew that with the Rapier alone he couldn't have been able to take it. Then the fifth move came and took him by surprise, being unable to really react in time, being struck directly. He can only cry out in pain.]
"Got you!!"
[These words quickly follow, and by pure reflex Kazuo would use his right to keep the shinai in place, right there where it hit him, using his own strength and the strength his demonic gauntlet provided him. Finally, he would use his left and swipe at Emi with his Rapier, aimed at her neck. However, and although even if it worked and could take a clean hit, he would still go ahead and stop himself right before making any contact that wasn't just a tap.]
