In the shadowy corridors of mid-eighteenth-century Europe, a sinister plot unfolds, weaving together fragmented pieces of literature and lore. Undead Girl Murder Farce plunges the audience into a world both eerily familiar and deliciously witty and original, filled with figures of fabled reputation. At its core, the anime follows Tsugaru Shinuchi, a half-demon killer called Oni, along with Aya Rand, a bodiless great detective who also happens to be immortal, and her servant Shizuki Hasei on their quest to find the mysterious man who stole Rand's body.
