I Summoned the Grim Reaper as My Starting Pet. (Little RPG, OP Skill, progression, Academy, summon)

Everyone awakened a legend. He awakened Death. In a world where summon divine dragons, celestial phoenixes, and god-tier beasts… Alex Carter summoned a tiny hooded skeleton with a toy scythe. F-Rank. Worthless. Failure. Expelled from the Celestial Academy. Abandoned by friends. Laughed at by the entire kingdom. But rankings lie. Because his “useless” summon isn’t a skeleton. It’s a sealed fragment of the true Grim Reaper — an existence so terrifying that even the gods united to seal it. And when his hidden Evolution System activates, everything changes. While others train one companion… Alex can evolve Death itself. Each corpse becomes a soldier. Each battlefield becomes his domain. Each war makes him stronger. Divine beasts? They bleed. Chosen heroes? They rot. Sacred academies? They burn. But the more he unlocks the Reaper’s power, the more the world trembles. Ancient gods awaken. Forgotten calamities stir. And powerful women—warriors, priestesses, demon nobles—are drawn to the boy who commands the end of all things. They called him trash. Now he will become the apocalypse. Death doesn’t ask for permission. It collects.
