What if Issei Claimed the Noble Daughters of the Multiverse?

What happens when the Boosted Gear isn't just a weapon, but the key to saving the entire multiverse? In this massive, full-length "What If" series, Issei Hyoudou's destiny expands far beyond the Underworld. When a sudden dimensional rift pulls Issei and Ddraig into the dark fantasy kingdom of Aevorn, he must free seven captive noble daughters and lead a brilliant phantom army deception to shatter a ruthless military occupation. But this is only the beginning. Alongside Rias and Akeno, Issei uncovers a terrifying universal truth: the "Foundation Layer"—the ancient force that binds all magic systems across every world—is under massive stress, and it has chosen the Boosted Gear as its ultimate equalizer. Watch as Issei answers the call across three distinct dimensions. From reuniting a shattered, twelve-person lineage network in the contested lands of Valdenmere alongside resistance leader Corven, to confronting an obsessive Architect in Caelmir who has imprisoned thirty Starbound navigators to control the Foundation itself. As Issei completes these cosmic resolutions, the Boosted Gear undergoes its ultimate evolution, becoming a transcendent presence capable of opening dimensional paths by choice. With three worlds saved and a mysterious fourth world, the Hollow Reach, waiting in the shadows, Issei's true power has only just awakened. 🎬 Written and Directed by: Me (Laxman Poojari) (If you enjoyed this massive multiverse series, be sure to smash that like button, drop a comment, and subscribe for more epic, movie-length What-Ifs!)
