Bousouitai Necroman

A student named Kotobuki Osoruji, who is deeply interested in special effects, discovers a costume in his late uncle's belongings that is linked to a tragic special effects show called "The Dead Body Necroman." The costume is inhabited by a spirit who wants to be a hero of justice, something he couldn't achieve in life. Encouraged by this spirit, Kotobuki and a club member named Kagura aim to use Necroman to fight crime in the real world. Initially, they handle strange events at their school, but soon face incidents beyond normal understanding. These involve crimes committed by individuals with supernatural abilities known as "Knockers." Kotobuki and Kagura decide to confront these villains using Necroman, who is particularly suited for battling enemies that transform into bizarre forms and commit evil acts.
