Dying is just data. Revenge is a 10- second delay. In a world ruled by powerful Hunter Guilds and the strict laws of the Hunter Association, Jaxen Vane was nothing more than an E-Rank laborer—disposable bait for corporate meat-grinders. Born with zero combat skills and a comatose sister to support, his only goal was survival. Until the day a routine dungeon raid turned into a deadly corporate cover-up. Trapped by mutated monsters and betrayed by his own vanguard, Jaxen accidentally triggers a late awakening. But his system isn't like the standard blue interfaces everyone else possesses. His is an anomaly—a glitched golden system that loads exactly ten seconds late. Whenever Jaxen suffers a fatal blow, his unique skill, **Hindsight Bias**, snaps his consciousness back exactly ten seconds into the past. He cannot outrun an A-Rank hunter, and he cannot overpower a C-Rank beast on raw stats alone. But with an endless loop of ten-second do-overs, he can memorize every strike, predict every trap, and turn his own brutal deaths into a flawless strategy board. Forced to hide his world-breaking ability from corrupt guilds, ruthless executives, and a high-ranking investigator who blackmails him into a shadow contract, Jaxen takes up a silver invitation to the National Hunter Academy. Hidden right under everyone's noses, the ultimate underdog begins to silently hoard stat points, master his broken system, and climb the ranks. They think he's just an unpolished gem with a lucky perception trait. They have no idea he’s already lived through their attacks ten seconds before they even think to swing.
