A man without magic, in a magical world that hates him, Bayón awoke in a place where the law of the strongest shows no mercy and humanity seems a luxury. Betrayed by fate and bound by chains he cannot break, his body bleeds, his mind remembers what it should not, and his soul faces the rottenness of the world.

Among gladiators, slaves, and shadows whispering death, he will learn that survival is not enough: to live, he must fight against everything-even himself.

Dark, brutal, and merciless, Spirit of Struggle is the story of someone who was not born a hero, but who does not fear becoming the villain.
