Unfortunately, given the state of the young crimson haired girl, Mariketa was unable to properly respond to the retort of Youko. If she had it probably would have been something rather simple and childish. Like pretending to be angry and sticking her tongue out at the man, as per something she would have done during the happier times long before this. Even so, she was trying really hard to fight what was coming, and Youko was doing his part to help. Though she'd succumbed to the darker intentions of the chakra which was poisoning her, she was still fighting it with all her might, until of course, the white haired man touched her. "Onii-chan..." there was a pause in her speech. Something about this touch, set the young woman off immediately and while he was shaking her by the shoulders she rather suddenly looked up at him, and with the swiftness of a practiced martial artist swept his hand away from her left shoulder, and drew back in the milisecond it would stake for a bone spike to pop out she'd already be headed for the place his hand was going, her apparent aim in this moment to spike this man's right hand to the wall by the forge. A sinister grin on her face as she did so. "We can't really allow that can we?" she asked of the starting of the seal. Of course, this wasn't really what Mariketa wanted, but in the interest of keeping Yuichi alive and eventually being ready for his comeback, obviously not letting this seal get too strong a hold would be the top priority. And an outlet for the sadistic tendencies both of these individuals possessed.
