Nighcisa

Nighcisa was the fourth Demon King. Originally a human, he was appointed directly by Planner, as Ssulal died prematurely. He was a heinous, brutal character that had no feeling but malice for mankind.

His brutal reign lasted 960 years.

Appearance and Abilities
Nighcisa looked like the more traditional depiction of a vampire lord. His skin was pale and his clothing regal. Nighcisa has gold curled hair, deep red eyes, pasty white skin, and wore aristocratic clothing.

Nighcisa saw humans as playthings and war as a game, his nature brought about mass genocide of the human race to the point where Supreme God Planner had to intervene and give humanity a fighting chance through the Hero System.

Nighcisa was very in touch with his vampiric side, moreso than other Demon Kings, he would often appear in villages to feed on random people, teleporting at will to anyone he thought looked good enough. The most vampiric Demon King, Nighcisa was a savage and uncaring monster that saw humans as toys for him to play with, he cared not for them or his own kind. It was for that reason that Dark Lords like Xavier looked up to him.

The Gods gave Nighcisa a special mission, prevent the spread of the Tenshi Sect to the mainland Continent.

Emperor Ishimaru Fujiwara of JAPAN was spreading Tenshiism as the official religion of his grand empire, and it was a rapidly expanding empire. Due to the fact that Tenshiism takes souls away from Ludo-Rathowm, this was a problem the Gods needed to nip in the bud quite quickly.

Nighcisa's subsequent war on mankind was so savage that even some of the Gods found it to be too much. At least half of the entire human population was brutally killed, including Emperor Fujiwara, and he wouldn't stop until every last human was dead. Supreme God Planner had to create the Hero System to prevent the annihilation of the Protagonist Race.

Eventually the Hero of the era met with and fought Nighcisa, and while the Demon King ultimately won the battle he was left with a wound that shaved 40 years from his life.

Nighcisa passed on his knowledge of the Hero System to his successor before dying. This resulting in the following rule being the worst era a Protagonist Race would ever experience.
