Yumi tried not to be too disturbed by the fact this creature was laughing, or the fact she swore it talked earlier. This was unlike anything they had fought before, it almost seemed to be intelligent. Smashing into it she'd caused the creature to collapse and lose its shape temporarily, smiling as she lowered herself onto the ground. "Cute? Call it what you want, I suppose. You won't be thinking its cute for long." She was only just getting started and if one punch did that much then this... Whatever it was wouldn't be too hard to dispatch. That was thr sentiment right up until the creature began to take form, growing from a non-uniform mess of goo into something more humanoid, something right out of a nightmare. 

Yumi's smile wavered slightly at the sight of the creature, a look of disgust conflicting with it as she couldn't tear her eyes from the grotesque being. "Experiment...? What are you talking about?" What experiment? Who knows, they had disrupted loads of experiments as of late, and who particularly cared where this creature came from? He was threatening the people of Uuonoe and that's all that she needed to know, it had to be dealt with. "It won't matter for long, Viral and I are going to take care of you here and now," Yumi threatened, assuming a fighting stance as she got ready for another attack. Aito just had to hang in there, they couldn't help him until this thing was beaten. Strong enough attacks could hurt it, she just had to pound away until it was no more. With the creature up in the air she used Ki to propel herself again, twisting her body around on approach and swinging out a hard kick, trying to knock it down towards Viral.
