A revenant is a type of ghost that died in anger and has come back to cause suffering by making others repeat the same death.
History
In "Kappa Spirit", Maggie and Mel Vera found out Lucy was being haunted by a vengeful spirit named Brenda Mancini. Mel believed her to be revenant due to the fact that she died in anger but the vanquishing spell failed on her, revealing that she was really just a conjuration of Lucy's.
