Getsu Fuuma Den

Released by Konami in Japan in 1987, Getsu Fuuma Den is an action-adventure game for the Famicom. The protagonist Fuuma's two elder brothers have been slain by the demon overlord Ryukotsuki, and it falls to the player to traverse three islands of the underworld, alternating between side-scrolling combat and town exploration while gathering weapons, equipment, and mystical arts before a final showdown with Ryukotsuki. The game blends action with RPG elements and is steeped in Japanese mythology and otherworldly aesthetics. Outside Japan it gained broader recognition when Fuuma appeared as a crossover character in Castlevania: Harmony of Despair.
