After a freak accident, Naoki Oikawa is reborn into a fantasy world brimming with magic, monsters, and insatiably horny women just waiting for a hero with a legendary libido. [1] Gifted with an overpowered 'Harem King' ability, Naoki's journey isn't about saving the world—it's about fucking it. The entire series chronicles his relentless sexual conquests, starting with the shy elf princess, Filia, whose tight, virginal cunt he claims in a steamy, drawn-out deflowering. He then moves on to the busty beast-girl, Mila, teaching her the joys of rough, animalistic fucking until she's screaming his name. [1] The narrative is a parade of raw, cum-drenched encounters; he takes on the stern knight-captain Tianne, breaking her pride by publicly fucking her into a quivering, obedient mess. [1] His cock becomes a legendary tool, satisfying the lustful demon queen Ruzé in orgiastic threesomes and foursomes, filling every one of her holes until she's dripping his seed. Each episode is a deep dive into explicit fantasies, from intense creampies and facials to hardcore group scenes where Naoki proves his inexhaustible stamina, turning his ever-growing harem of fantasy babes into his personal fuck-slaves.
