The blue-haired swordsman was about to say something when he felt a cut on his cheeks. Blood started dripping from the cut and he immediately forged water essence into an armor around his body.

A small magic circle appeared outside the mecha as something struck its body. Just when the person inside thought of something, another small magic circle appeared.

Then another one, and another one. 

Soon, the mecha was entirely covered in magic circles that could only protect against the invisible attacks.

If this continued, the mana stone that powered the mecha would run dry.

The Succubus felt something cut her skin which immediately reformed as her healing factor kicked in. However, the cut continued happening and she was forced to teleport away.

Healing oneself cost a lot of Magicules, and she couldn't waste it right now. However, even when she teleported to a different location, the cut still continued.
