Ruka is an Orc that appears in Monster Musume: Everyday Life with Monster Girls Online.

Zoological Classification
Orcs are a race of brutish, aggressive and generally lustful psudeohumans. Possessing prominent fangs and a snout, their features tend to be "pig-like" in appearance. Taller and thicker than a human by half, they would have about the strength a bear, and have noses capable of accurate olfactory sense to up to a kilometer out.

Aggressive scavengers and opportunistic carnivores, while they possesses a low cunning and a low intelligence when compared to other more intellectual species, Orcs do possess a crude culture of their own. Violent by nature, they will fight ferociously if compelled but tend towards more chaotic/destructive behavior such as pillaging, rape and/or cowardice.
