Without even a motion, a wall of Umbra burst into existance before Zetsumi, the blast of Espillion impacting against it, sending a ripple through the wall anc causing it to crumple in around the blast, each straining against the other, two equal forces struggling against one another, as the Espillion consumed the Umbra, and it in turn consumed it's counterpart. At last, both were gone completly, and neither Zetsumi, nor Unaori, had moved an inch.
With a sadistic smile, Zetsumi looked up into Unaori's eyes as darkness enveloped him, melding and twisting together to form a similar armour over his own body. Zetsumi's spiked Umbra-Armour was jointed, and covered only his chest, arms, and upper legs. He hadn't had to use the Umbral armour in some time. It felt good... familar. It had seemed only apt.
Raising his left arm in the air, he tore off his sleeve, and ran a finger down it's length. Where flesh touched flesh, angry, vibrant red marks burst forth on the skin, glowing, blood-red, and spread across his entire arm, eventually fading, leaving his arm with a dim red glow.
"I've added a few new tricks to my arsenal, since last we met..." He said with a smile, and then, there was a flicker of psuedomotion, and before one could even blink, he'd lept through the air, bridging the distance between himself and Unaori in a fraction of a second, his red arm stabbing directly towards his foe's Chestplate with enough force to rip through almost any defences.
