I Keep Dying to Save the Beast

When a strange, glowing parcel containing a snarky, multi-eyed winged fox arrives on my doorstep, I am thrust into the Karmic Courier System. My mission? Enter the melodramatic novel 'The Saintess of the Gilded Sands', save the tragic beastmen used as cannon fodder, and survive. As a chronically empathetic veterinary nurse, I immediately clash with Kaveh, a hostile snow-leopard gladiator who thinks I am just another cruel noble. We become bitter rivals in the Sun-Forge Citadel’s tournaments, but I cannot help but slowly melt his icy heart with endless bandages and smuggled sweets. When the scheming 'pure' protagonist Roshanak sets a lethal trap, I do what any soft-hearted fool would: I throw myself in front of Kaveh, taking the fatal blow meant for him. The System flashes: *Delivery Failed. Rerouting.* I wake up in the next world, devastated that I failed to save him. But I misunderstood the rules entirely. My death did not reset his world - it broke his chains. Now, a terrifyingly overpowered snow-leopard beastman is tearing through the multiverse to brutally slaughter those who hurt me. How many yandere gladiators will I accidentally collect before I realize I am not failing at all?
