Is part of the 20 Major clan of the Demon Race.
"They had a fierce and evil looking appearance, quite similar to monstrous abominations that were shaped like humans. Their height was roughly 1.7 meters, they were naked, and on the lower part of the body were meticulous black-colored scales. On the upper portion of their bodies, their skin was purple black-colored and the head had three eyes; but the fact they had four arms was the most peculiar. That’s right, each of these monsters had four arms and each of these arms were shaped similarly to a needle: their little arms ended in a point. Their sharp tips of these stingers emitted a cold light."
The innate peculiarity of the members of the Luke clan was that they had four stinger-shaped hands. Their frontal fighting strength was not too high, but they were experts at mounting sneak attacks. With their four arms simultaneously held high above their head, they were capable of drilling underground with a high speed comparable to sprints. Their attack arrived suddenly from underneath, causing people to be taken off guard and leaving them unable to defend effectively against it.
