Mysteries of Sacra [Isekai] [Weak to OP] [Beast Companion]

Thrown into a world of beasts and magic, Kai must fight to survive and hold on to the last pieces of his humanity. One moment, Kai was an ordinary teenager on Earth. The next, he’s torn into Sacra, a savage realm ruled by spirit beasts, ancient mana, and fallen gods. Alone, untrained, and relentlessly hunted, Kai’s only goal is survival. But when he saves a dying beast and somehow kills a deadly predator, everything changes. He discovers a terrifying power: the ability to absorb the souls of his enemies and claim their skills as his own. Each soul strengthens him, but also warps him. Their memories claw at his mind, threatening to consume what’s left of the boy he once was. Can Kai master the powers within and become something new, something the world of Sacra has never seen? Or will he lose himself to the darkness and become the very monster he fears? What to expect: Follow Kai as he struggles to balance unimaginable power with the fragile threads of his humanity.In a world where kindness is weakness and morality is a luxury only the strong can afford, Kai must decide who he wants to be and what he's willing to sacrifice. His companions are more than allies; they're his anchor.Umbra, fierce and loyal, and Scry, wise and offlandish, refuse to let him lose himself to the darkness growing within. To escape Sacra and return to Earth, if that’s even possible, Kai will have to evolve into something new.  Along the way, he’ll find allies, rivals, and maybe even a flicker of love…But every step forward brings him closer to a prophecy no one dares to speak. *** Chapters are uploaded every week, Mon -Wed - Fri Thank you all  >>>Winner of the Royal Road Writathon challenge<<<
