Hamatora is a "super-powered mystery x battle entertainment" mixed-media project. The project is a collaboration between chief director Seiji Kishi (Danganronpa: The Animation, Persona 4: The Animation, Angel Beats!), project composition writer Yukinori Kitajima (Senran Kagura, Professor Layton vs. Phoenix Wright: Ace Attorney) and original character designer Yūki Kodama (Blood Lad manga).
In addition to the anime, Kitajima and Kodama will launch a manga version in the 51st issue of Shueisha's Young Jump magazine on November 21. A video game "and more" will then follow.
