Renka never cared about his old world. As an orphan, he saw life as a struggle, so when he was transported to a mysterious realm, he welcomed it. But unlike the others who arrived, he wasn't reborn as a human-he became a fox. The only one.
In this brutal world, survival is everything. A leveling system governs all, monsters lurk in every shadow, and every ten days, the difficulty spikes. To regain his human form, Renka must hunt, kill, and absorb his enemies' powers-choosing only one ability per victory. But the system has one cruel rule: this is a true death game. No respawns. No second chances.
As Renka grows stronger, he encounters a blind swordswoman abandoned by her party. Though he doesn't trust anyone, he sees his own loneliness reflected in her. Together, they must carve their path through a world where only the strongest survive.
With each level-up, the stakes rise. The monsters get smarter. The world gets harsher. And Renka begins to wonder-was this really an opportunity for a better life, or is he just another pawn in a twisted game?
