Niken secretly set up a magic barrier around her to withstand any attack from the mix-blood wizard. Edward and Kazuto advised her to avoid and run away as soon as possible if she met one of them.
Niken might be able to beat this guy if only this person only had one green magic circle. But Niken didn't know the level of this person's magic circle, and she didn't know if she could fight this person without taking away her source of life energy.
It would be better if she immediately ran and looked for a temporary hiding place.
But could she even run away from this mix-blood wizard? It would be futile if this wizard determined to hunt her down and beat her.
Her luck did not get better when she noticed her pursuers now catching up with her from behind.
