Name
Tachikama Yami
Called "Darkness of the Severed Head"

Gender
Takes on a male form, but has no true gender.

Age
Appears to be in his mid-20's. His real age has been long forgotten.

Sexuality
Not at all interested in romance or sexual interactions, though he seems to lean toward males.

Appearance
Spirit
As a spirit, he has the appearance of a black-headed canine with piercing yellow eyes, which appear to glow in the darkness. His body is thin, bones rippling through leathery skin. Past his neck, his pelt is a ghostly white, and his body wisps behind him in a lean, snake-like stream.

Human / Yokai
When in his hidden form as a human, which he usually travels about in, Yami has blue-black hair and those same, iridescent yellow eyes, almost resembling that of a wolf. He usually wears monochrome clothing of various patterns, and doesn't stand out much at all, luckily enough. The form is, after all, meant to draw attention away from himself.

Personality
He never says more than a sentence at a time, speaking as little as possible and always wearing the same blank, indifferent expression. He has a huge temper, and can easily be pushed over the edge by even the smallest of things. He tends to resort to violence at all times, whether necessary or not, and almost always wins. His opponents are never left alive, and never given any mercy.

Abilities
Increased stamina and general senses. He has incredible eyesight, taste, smell and hearing, and as such is often chained to humans with a grudge for someone they need to find the location of; he is in general an excellent tracker.

He can fly for however long he needs to, but cannot take anyone along. The only form he is able to travel this way in is his true spirit form, which renders him incapable of physically touching anyone but his master's target.

He is able to decide who can and cannot see him, however this ability spans only to those without spiritual power. Priests and holymen can see him no matter what he does, as can his master and other spirits.

Possession; he can control mortals without spiritual power or strong wills. Thus, the only mortals he can possess are those with an unstable conscious.

Master
Akimashiro Kumori
An unstable man in his teens with a grudge toward those who "did him wrong" when he was young. Yami despises the child, and would do anything to get rid of him if he could. Along with following Kumori's constant, irrational orders, he also searches for a way to destroy the child without in turn destroying himself, for it is taboo for a spirit to directly harm it's master.
