Eisen pulled out his Demonic Sword and watched as Satel simply flew into the sky to make way for the fight to properly unfold.
The monster that was currently rushing at Eisen with madness in its eyes now seemed anything but human. Sure, it still had the rough physical form of a human, but it moved in ways that were practically impossible for a normal person to achieve. For one, its joints weren't moving in the way that Eisen expected. Rather than just being able to twist into mainly one direction, the joints of this monster allowed it to twist all of its limbs into any direction that it wanted to.
Hence, it was able to really crawl at Eisen at high speeds and in a rather horrific manner at the same time. The old man readied himself for the moment that the monster would reach him. It was always better to be able to react to an attack rather to be the one that instigated it, as far as Eisen was concerned.
