In a world ruled by the iron law of Beast Taming, your summoned spirit is your entire worth. A high-ranking beast guarantees luxury, power, and respect. A low-ranking beast condemns you to a life of servitude. For seventeen years, Leo lived in the shadows of the city elite, waiting for the Day of Summoning to change his fate. Instead, it became his living nightmare. Humiliated in front of thousands, mocked by the person he trusted most, and left with a trash-tier ranking, Leo became the joke of the city.But when the elite discarded a dying, mutated defect beast and sentenced it to execution, Leo felt a strange, ancient resonance. He chose to form a soul pact with the creature, drawing the ultimate ridicule from the crowd. They thought he had sealed his own doom. They were wrong. What the world saw as a broken defect was actually a dormant, forbidden myth from the dawn of time. As the blood pact activates, a terrifying power begins to wake, and the people who trampled on Leo’s dignity are about to learn that some gods should never be angered.
