A Blood Summoner's Rise

The System arrived on Day Two. Ren waited until Day Seven. While others scrambled for classes  warriors, mages, archers  Ren watched from the shadows. He watched the strong prey on the weak. He watched mages burn out their own minds. He watched comrades drive knives into each other's backs for scraps. The System was not salvation. It was a tool. And tools kill people who don't know how to use them. On Day Seven, cornered in a burning building with two stab wounds and a dead man at his feet, Ren finally pressed Yes. Class Assigned: Summoner — Blood Patch Variant. The price? Blood. Always blood. Every contract demands a sacrifice, and what crawls out of the darkness for his first summon is no loyal companion. It's a predator that openly promises to devour him the moment he shows weakness. Ren smiles back. He's been killing to survive for seven days. One more threat won't break him. He was nobody before the apocalypse  a faceless office drone crushed under overtime and a boss he despised. He has no family to avenge. No world to save. No chosen destiny. He has one goal: win. No matter who he has to kill. No matter what he has to summon. No matter how much blood it costs.
