Obsidian Release: Plague Consecration

Obsidian Release: Plague Consecration is an Obsidian Release technique developed and used by the sole demonstrated user of that kekkei genkai, Kojimaru Sansokajiya. It, unlike other more basic and orthodox Obsidian Release jutsu, makes use of the Obsidian Release's ability to contain and transfer harmful substances such as infectious material. On contact with the specially modified obsidian, a target becomes infected with a special chakra that causes the proteins in their bodies to turn into a particularly voracious type of prion, causing unnaturally rapid necrosis, killing cells, and spreads swiftly, affecting the target in such a way that they can degenerate into varying degrees of insanity, which lasts for different amounts of time depending on the potency.
