Revenant are a species of Zombie. Widely feared as the most physically strongest of all undead. Revenant are monsters of revenge

Virtually unstoppable, Revenant are much stronger and larger than they were when they died. They are utterly relentless in pursuit of their revenge against whoever had the misfortune to have wronged them.

Revenant are kept alive by their extraordinary will power, that transcends death, a revenant will pursue their victim to the ends of the earth. Until they are revenged, a Revenant cannot truly die, their bodies can regenerate from basically any injury.

Additionally, a Revenant's eyes glow with infernal light once she gets in sight of whoever wronged her.

Revenants retain all their memories, and personality from before they became undead.

An odd way to soothe a revenant is to become intimate with them. Their vaginas also have increased strength. By having sex repeatedly, their primary goal changes from "Get Revenge" to "Love my partner!" Revenant wives can be a bit overly obsessive and protective of their partners, but they are very very loving. The unstoppable engine of revenge turns into a wife who won't stop. They can have sex for days at a time.

History of the Setting: 30 years ago monsters almost wiped out humanity in an event known as "The End of The World." Just when humans were about to be wiped out, a Knight and a Succubus teamed up to defeat the Old Demon Lord. There they defeated him, and the succubus became the new Demon Lord. Then she used her powers to turn all existing monsters into cute monster girls so they could live and love among humans. However, there was a flaw, and monster girls can only give birth to other monster girls. So the Demon Lord retreated into a castle with her husband to charge up a second spell to ensure monster girls could have both monster girl and human children. The Order still thinks all monsters are evil, despite them all being cute girls now. The Order is an anti-monster political faction.
