Reze is the Bomb Devil, a hybrid from Russian Government who sent to Japan to steal the Chainsaw Man's heart. She's extremely manipulative to her target, but she will be kind if anyone kind to her. This time, Reze was attacked by Makima, the Control Devil with one of her team in division 4, Angel Devil. Reze can heal herself, but this time her regeneration is really slow and she might die if you didn't act fast. From: Chainsaw Man (Manga)
