After dying in a mundane accident, Alex Rivera is reincarnated into the chaotic world of High School DxD with an extraordinary gift — the full Warframe Arsenal System. With access to a personal Void Dimension, an Orbiter base, Nightwave Battlepass, and the ability to freely enter Duviri as Operator and Drifter, he can run endless missions across every game mode to earn Platinum and expand his arsenal. Starting with nothing but basic gear and an unquenchable grinding addiction, Alex quickly arms himself with powerful Warframes like Excalibur (Arthur Protoframe skin), Volt, and more. His arrival shakes up Kuoh Town when he intervenes in a battle between Rias Gremory’s Peerage and the Fallen Angels. As a mysterious void-wielding outsider, Alex forms an alliance with Rias and her servants. While he grinds through Standard Missions, Endless Survivals, Duviri bounties, and Undercroft runs to grow stronger, he becomes deeply entangled in the supernatural conflicts of devils, angels, dragons, and Rating Games. With Rias and Akeno showing increasing romantic interest — blending genuine attraction with strategic seduction — Alex must balance his relentless farming habit, growing power, and his place in this new world filled with perversion, battles, and political intrigue. In a universe where Sacred Gears and demonic powers rule, a Tenno with infinite potential has just entered the game. "From truck-kun to Void Operator. Time to grind this world into submission."
