Best friend of Kate and good friend of the other three up until the night she died.
She was about to be reanimated like the other four until Hervé's forces kidnapped her. Her real corpse is discovered in the woods, and it is her death which draws the attention of the police. Lise is being used by Hervé's family to try to find a cure for their family's curse, and after they reanimate her, she has very little memories of the quartet.
In later episodes, she fights in her manifested state and can actually come back to her regular stage.
Her reincarnation happens to be Edgar's younger sister, Louise, whom is fixated on the Dead Girls the moment she met them all at her school. Why she's fixated on them was because they're immortal. She also holds a secret of her own.
