- Description from novelbuddy

“Isn't this the weak young master of the Valhalla family?”“Hahaha! I heard he only knows how to waste money... Completely useless.”Another voice, dripping with false pity, chimed in.“Both his sister and brother are Tamers, strong ones at that. While him... the eldest... pathetic!!”The final word, spat out like a curse, hung in the air: “Useless!”In this world, where the bond with powerful Beasts dictated one's standing, where strength was synonymous with the ferocity and strength of your companion.Christopher Valhalla was an anomaly. He found solace not in the thrill of battle or the acquisition of monstrous power, but in the simple, fleeting joys of life. He enjoyed partying, clubs, and women.He offered no retort to the cruel rumors that trailed him like a shadow. Because, truth be told, a knot of fear tightened in his stomach at the mere sight of the majestic, often terrifying, creatures that others commanded.But every life, regardless of its perceived worth, eventually finds its end. For Christopher, it came not in the jaws of a wild Beast, nor in a duel he was ill-equipped for, but in the insidious grip of a rare and incurable sickness.Some days later his flame flickered and he died, leaving behind a void filled with the echoes of scorn.Yet, where one life ended, another began. In the silent stillness of Christopher's vacant shell, a new consciousness stirred. A soul, bearing the weight of unmatched power and a reputation that sent shivers down the spines of even the most formidable Tamers, had arrived.This was the Supreme Tamer, a legend whispered in hushed tones across the world, a force of nature who had inexplicably perished at the hands of betrayal.Given this unexpected second chance, the Supreme Tamer, now inhabiting the frail form of Christopher Valhalla, felt a strange sense of acceptance. He looked upon the unfamiliar yet familiar faces of his new family – the concerned worry etched on their features – and a flicker of something akin to kinship sparked within him.A silent vow formed in his mind, hardening into an unbreakable resolve.The rumors that clung to this body like a shroud would be torn away. And the five Master Tamers who had orchestrated his demise in his previous life… They would learn the true meaning of fear.Their betrayal would be answered, not with petty revenge, but with the full, terrifying might of the Supreme Tamer, reborn. The world was about to discover that “useless” could be the most dangerous disguise of all.
