The Cursed Killing Grounds: May Those Who Curse Me Suffer the Consequences

[Evil ghosts may not always kill people, but they always curse them!] [Humans cannot kill ghosts, but they can kill them with a curse!] [The one who curses you may not be a ghost. It could be a person!] [Welcome back to the Land of Ghostly Curses~] [Current B-rank Ghostly Curse Survival Game: Poison Curse Blood Feast] [Ghostly Curse traits currently held: A-rank [Drop Dead]: A death curse born of an evil ghost's resentment. When the countdown ends, your heart will stop. If someone deliberately provokes this curse, the source is considered to be that person, not the evil ghost itself. S-rank [???]: A curse of unknown effect and unknown origin... S-rank [Curse Reversal]: Any curse below S-rank placed on you will rebound onto the one who cast it when it takes effect~ Anyone who places an S-rank or higher curse on you will share half of its effect with you. Now you never have to worry about not knowing who's cursing you~]
