This is an action role-playing game (RPG) in which players assume the role of a detective with magical powers who investigates a series of disappearances in a 1920's Japanese town. Players can summon demons to help out with the investigation and to battle other creatures and human enemies. During combat, players can slash enemies with swords or order their demons to use magic attacks (e.g., fire, ice lightning). Blood sometimes pools under enemies' feet when they are struck, and blood occasionally stains the floors and walls of the dungeon and town environments. Some female demons wear outfits that expose deep cleavage, wear body paint for clothing, or are dressed in rose vines that barely cover their breasts. A few demons have suggestive appearances, including creatures with phallic-shaped heads and torsos.
