RAISING CANDY Candy

Grace hasn't been feeling well lately and has been thinking of committing suicide. It didn't help that she was involved in a bank robbery. Before the situation escalated, a strange girl smashed through the skylight and saved them...only she actually didn't save them. She is the cannibal serial killer with a kill count of over eight thousand who is known to let victims go just to hunt them down again. She proceeds to kill and eat almost all the hostages, including Grace's best friend, before letting the rest go.

Sure enough, Grace hears that all the other "survivors" have been killed and eaten besides for her. After waiting for her death to come willingly, the serial killer finally visits her, only she doesn't kill Grace but instead complains in a completely childish way how Grace wasn't "bright". Aimu, the serial killer who turns out to be an undead who thinks people are candy, "kidnaps" Grace to try and make her bright.

Unfortunately, the two soon developed feelings for each other. Grace, not wanting to end her time with Aimu but also feeling like she has to die and it has to be by Aimu, stays with her. Aimu on the other hand realizes that she loves Grace early on and doesn't want to kill her at all. However, she made a promise to eat Grace, and she keeps her promises no matter what. Of course, it doesn't help that Aimu is still an insane serial killer who has killed almost everyone she has come into contact with or that Grace is the daughter of a powerful noble and that she is "special" to the government.

But when an organization bent on turning the human population into mindless mutants sets their eyes on the city Grace and Aimu live in, Aimu and Grace find themselves as a block in their way, and they might even have to be "heroes" and stop them. Well, really it is the fact that the leader of the organization is unwilling to wrap his head around the fact that confronting Aimu in any way means death and Aimu can single-handedly slaughter humanity by herself.
