Black Kishin

The Black Kishin was the first Oni to ever set foot Hi no Moto and the central responsible for the Oni invasion in the country.

Appearance
The Black Kishin was briefly seen in the distance as a giant black wall spanning over the horizon. It is so massive that it has engulfed half of Hi no Moto from the east, effectively splitting the country in two by itself. At the base of the wall are insect-like legs it uses to advance as it lays waste to territory in its proximity.

Personality
Not much is known about its personality, except it is an aggressive invader who cares little about laying waste and destruction in its wake, committing indiscriminate slaughter when it first arrived in the country and continuing it for 150 years. Its true purpose if any is unknown as it seemingly endulges itself in mindless destruction and unquenchable hunger as it continues to grow larger and stronger.

Abilities
Not much is known about the Black Kishin, but it is by far and above the most powerful Kishin and by proxy Oni in existence. It was so mighty that no human was ever a match to its might when it invaded Hi no Moto, easily scorching opposition to extinction. It has remained undefeated by 150 years, during which it has grown stronger as a result of continuous ore consumption. It has engulfed half of the country at present time.
