Tatsuki, as she'd now taken to calling herself looked upon the lad formerly known as Kou as he named himself. This was after of course, a growling correction of her previous speech. Somehow something about the way this was done, made her left brow raise, in slight curiosity. Platinum blonde hair which was close to white flowed down her back in gentle waves as she felt this newfound animosity and the sensation within her own body pulled her towards it. "A-ka-shi~" she repeated the lad's name with nothing but amusement in her tone, and the slightest lisp created by a combination of a forked tongue and new fangs. But there was a seriousness in her eyes which implied she understood the challenge presented by such a name. She looked over his new attire, and didn't get a chance to see her own, which seemed a bit like several tiny armor pieces strung together, all the way down her arms and up her legs but with her rear visible in small lace panties. Beyond this, her legs were also trimmed in lace and opened before her shin armor started and ended leaving her barefoot. Even her tail gained armor and the blue color of it became hidden underneath."Figures you'd choose that, still..." she seemed to be thinking something about this, but as both of the people in this pair had been named, they'd soon find time returning around themselves, even as they stared each other down. Their new presences were enough to initially cause confusion in the Berserkers. At first they refused to approach, it seemed the combined presences of these people who were staring daggers at each other was almost enough to deter them, but another roar from both of them seemed to add a bit of courage. They charged ahead at their intended targets but for her part, Tatsuki never looked away from Akashi. Within herself she felt a deep stirring like a monster thrashing about beneath the surface of the ocean's waves. Her own challenging nature present in an unaltered gaze.
