A Keyblade modeled after Akira Fudo, the titular DEVILMAN! This Keyblade is designed to maximize damage and Fire skills! The hilt of the blade is designed after Devilman's head, with an upside down pentagram being the opening for the handle. The shaft of the blade combines forms of Devilman and Amon's different appearances, with some showing him to have more of an exoskeleton and others being more fleshlike. The teeth are designed after the bright red wings of Devilman in the original Anime. The Keychain is Devilman's tail, and the token being his belt icon from the original anime.
The World logo is Devil World, a world filled with Devils! The design is a reference to the original manga's title, with elements from Devilman Crybaby's logo. The name comes from the term meaning to argue from another point of view that is not your own. This is a reference to Akira using a devil's powers to fight other devils!
