Black Hounds (黒妖犬) are insanely vicious wild creatures that will hunt enemies down until it successfully finishes them.

Appearance
A Black Hound is a dog-like creature with black fur. It is covered in scars and his neck is the only area with white fur. It's tail is fairly short and all of it's teeth are sharp and piercing. When it feels threatened, it grows larger in size, and when it does not feel intimidated, it shrinks into a cute little dog. When it is in the form of a small dog, it's scars are not visible.

Personality
They are stubborn vicious creatures that will not give up on a prey until it successfully defeats it. When they feel threatened, they will increase in size in an attempt to triumph. On the other hand, it appears that they respect their masters and act like a normal puppy before them.

Abilities/Equipment
They appear to be pretty quick on their feet and fast enough to easily avoid the attacks of Holy Knight apprentices. Black Hounds also change in size depending on how threatened they feel (the more threatened they are, the bigger they get).

Trivia

 * Black Hounds are a reference to the Black dog (ghost) in the folklores of the British Isles.
