Eiji Kagemaru—known online as Eight—never imagined his final moments would involve a rage-quit, scattered pizza crusts, and his own devices mocking his virginity. One split second of distraction, a phone suspended impossibly in air, and a snarky system voice marked the end of his first life. Now he's transmigrated into an alternate world, stripped bare in an endless void, surrounded by glowing screens, facing an unexpected reality: his Almighty system isn't a cold interface but a lewd girl with an impossibly filthy mind and kinkiest fantasies imaginable. She's made the rules crystal clear—complete her quests, indulge her darkest desires, or perish in this foreign realm. Death here means permanent; no escape back to his original world, no second chances. Eight must navigate this twisted new existence where his system's insatiable appetite and crude humor become his only tools for survival in a world that seems designed specifically to break him.
