Neuronist Painkill  

, ニューロニスト・ペインキル

The Great Tomb of Nazarick contains a unique character known as the Neuronist NPC. This artificial intelligence investigator specializes in interrogating prisoners and takes pleasure in doing so. Its favorite cuisine consists of brains, which it finds particularly satisfying to consume. Despite being an asexual species, the Neuronist identifies itself as "onee-san," a term often used by Japanese characters to refer to older females. The Neuronist's physical form resembles that of a massive, bloated corpse with tentacles and elongated fingers featuring razor-sharp nails.
