Yoru is a powerful devil from the Chainsaw Man manga series. When in possession of a human host, she gains tremendous strength, agility, and endurance. She also wields a massive, razor-sharp scythe that she uses to cut down her enemies. As a member of the Four Horsemen, Yoru is known by many names including the War Devil and the Weapon Devil. Her powers are derived from her contract with the Japanese Public Safety Devil Hunters, and she has a strong dislike for Chainsaw Man himself.
