Nighcisa

About
Nighcisa was the fourth Demon King. Originally a human, he was appointed directly to the position of Demon King by the Supreme God Planner, as the previous Demon King Ssulal died prematurely before she could choose an heir. Nighcisa was a heinous, brutal being that had no feeling but malice for mankind.

Nighcisa saw humans as playthings and war as a game. His disdain for human life lead to a mass genocide of the human race, to the point where Planner had to intervene before humanity was driven extinct.

Nighcisa was not only savage and uncaring towards humans but was equally disdainful of the lives of Dark Lords or monsters, unafraid to throw them away on a whim. It was for that reason that brutal Dark Lords like Xavier looked up to him, admiring his cruelty.

Nighcisa was the only Demon King to be specifically given a task by the Gods. Emperor Ishimaru Fujiwara of JAPAN was spreading Tenshiism as the official religion of his new grand empire and it was rapidly expanding out from JAPAN. Due to the fact that Tenshiism takes souls away from Ludo-Rathowm, this was a problem the Gods needed to eliminate quickly. The Gods tasked Nighcisa with a special mission: prevent the spread of the Tenshi Sect to the mainland Continent by whatever means necessary.

Nighcisa's ensuing war against 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 savagely killed, including Emperor Fujiwara, and Nighcisa's intention was to continue until every last human was dead. To give humanity a fighting chance, the Gods' response to Nighcisa's brutality lead to the creation of the Hero System as a means of preventing the annihilation of the Protagonist Race.

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

By the end of the war, Nighcisa was ultimately successful in keeping Tenshiism local to JAPAN and out of the rest of The Continent.

Before dying, Nighcisa passed on his knowledge of the Hero System to his successor, Gele. With the Monster Realm now armed with a knowledge of the Hero System - and how to manipulate it - the ensuing period became being the worst era a Protagonist Race would ever experience.

Despite constant warfare, many enemies, and marring at the hands of a Hero, Nighcisa's brutal reign lasted 960 years out of a possible 1000.

Appearance and Abilities
Nighcisa looked like the traditional depiction of a vampire lord. He had curled gold hair, deep red eyes, pasty white skin, and wore aristocratic clothing.

Nighcisa was very in touch with his vampiric side, moreso than other vampiric seeming Demon Kings, and he would often appear in villages to feed on random people. No one was safe from his intentions, as Nighcisa could teleport at will to anyone he thought looked delicious enough.
