High School D×D: Operation Paradise Infinity

High School D×D: Operation Paradise Infinity is a free-to-play RPG based on the TV anime series High School D×D. Through turn-based battles player raise the heroines from the original series with upgrades to powerful fighters. The game adapts characters, themes, and settings from the anime while presenting them within a party-based RPG structure.

Gameplay centers on forming and managing a team of characters drawn from the series. Each character has defined skills, attributes, rarity tiers, and progression systems such as star levels and equipment. As players advance through stages, characters can be enhanced to improve combat effectiveness. Battles are designed around deploying a customized team to clear successive encounters.

The game features a large roster available at launch, with additional characters, limited-time skins, and exclusive artwork through ongoing updates and events. Character acquisition primarily uses a gacha-style summoning system, which distributes characters of varying rarity. Progression rewards, login bonuses, and time-limited campaigns provide alternative ways to obtain allies and resources.

The game places strong emphasis on original, game-exclusive character illustrations and collectible gallery content. These visuals include unique costumes and themed scenarios created specifically for the game, distinct from those seen in the anime. Monetization is handled through optional in-game purchases, while the core experience remains playable without mandatory spending.

The title draws directly from the High School D×D: Hero anime continuity, the fourth season of the franchise.
