Onryo

Onryo (or Grudges as they are sometimes called) are a 99 Black level monster, so they are the highest level of danger. They are possibly the most dangerous monster ever.

History
Onryo were made by Rotet

Biology
Onryo are undead monsters with unstoppable powers. They are unkillable as their entire biology is linked to a curse, the Vengeance Curse. They are created as a being that goes through a horrific death and have their corpses defiled and cursed and their anger for this creates a large amount of insanity strong enough that it automatically enters the soul and the entire soul, mind and heart is turned insane. For this, the Grim Reaper imprisons the soul on the planet the soul died on within the location they died. Since they are locked from the afterlife and are returned to the body with their blood dried up and their hair darkened by their insanity and thirst for vengeance while their eyes turn red with rage, making an Onryo. They are imprisoned within the location they died in, therefore creating a Curse Radius and anyone who enters the radius is hunted by the Onryō as they can't control their rage and attack anyone they see as the rage and insanity they have makes them unable to control their urges to kill. They hunt the person and kill them and eat their soul and absorb it into their soul and make it a ghoul, and they use it to make portals in the form of the hands of the dead soul.

Appearance
The gender they are typically seen as is a woman but there are male ones but they are less common

Skills

 * Unkillable: Onryos are already dead and they have their soul locked from the afterlife, so they cannot succumb to the wounds they take and are even able to act as though the wound isn't even there.
 * Ghoul: Onryos are able to absorb souls and weaponise them, unlike Vampires or Necromancers, they instead use them to make portals out of the souls hands where only the using Onryō can enter as other types of species will be torn apart by the hands.
