High School DxD Operation Paradise Infinity

High School DxD Operation Paradise Infinity is a role-playing game based on the High School DxD anime series, which is adapted from a light novel series published under Kadokawa's Fantasia Bunko imprint. The player forms a party from more than 60 characters from the series, including Issei Hyoudou and Rias Gremory, and arranges it around each character's skills and attributes. The story is original to the game, and all character artwork was drawn specifically for it, including an in-game gallery of original outfits. Characters are obtained through a random draw. The game runs in a web browser on PC and smartphones with no installation.
