Discover The Best Movies and TV Shows Like High School DxD

Issei Hyodo is an ordinary, perverted high school student whose mundane existence shatters when his first-ever date, a beautiful girl named Yuma Amano, murders him on their second date. Yuma reveals herself as a fallen angel and slays Issei for the Sacred Gear—a powerful, divine artifact—dormant within his body: the Boosted Gear, which temporarily doubles the wielder's power. Rias Gremory, a stunning red-haired upperclassman who is secretly a high-class devil, resurrects Issei as her servant using evil pieces. Issei wakes up as a devil and is forced to join the Occult Research Club, a front for Rias’s peerage. Initially motivated purely by his lecherous ambition to climb the devil hierarchy and build his own "harem," Issei quickly shifts his priority to protecting Rias and his new comrades. He learns to channel the soul of Ddraig, the legendary Red Dragon Emperor trapped inside his Boosted Gear. As Issei trains, he grows closer to Rias, Asia Argento—an exiled nun he saves—and other girls in the club, including the brooding knight Kiba, the hyperactive witch Koneko, and the fallen angel Asia. Tensions escalate in the supernatural world as factions of angels, fallen angels, and devils clash. Issei's ultimate motivation becomes proving his worth in a rigid, caste-based society that looks down on reincarnated devils and low-class pawns. The dramatic peak of the first major arc arrives when Rias is forced into an unwanted arranged marriage with Riser Phoenix, an arrogant high-class devil. Refusing to accept her subjugation, Issei challenges Riser to a rating game. Through sheer willpower, desperate training, and unlocking the dangerous Juggernaut Drive—a power-boosting transformation that exacts a heavy toll on his humanity—Issei defeats Riser. He saves Rias from her fate and earns her romantic affection, cementing his place in the supernatural underworld. Throughout subsequent conflicts, Issei faces rogue factions, ancient dragons, and god-like beings, continually evolving from a weak, perverted mortal into a formidable warrior. Driven by a fierce loyalty to Rias and a desire to protect the peace between the three biblical factions, Issei fights not just for his own audacious dreams, but to redefine his destiny. He embraces the heavy burdens of the Red Dragon Emperor, proving that even a lowly human turned devil can alter the balance of power in a sprawling, dangerous universe of myths and monsters.
