In a world teetering on the edge of ruin, a boy named Echo—once branded an experiment gone wrong—sets out on a journey with his new loyal friends to reclaim more than just his identity. Only by restoring the mythical power of Halo can they hope to stand against Masakuur, the God of Death, whose return threatens all life. As they face ancient trials and awaken long-lost powers, Echo fights not just to save the world, but to prove that even the broken can become heroes.
