Within the mist-shrouded, isolated realm of Kushinada, survival depends on a grim tradition: each festival, a living offering must be cast into the open ocean to quell the wrath of Lord Greed Susanoo, the fearsome guardian deity of the deep. Believing his life holds little value, young Vante voluntarily steps onto the ceremonial altar and plunges into the churning abyss below. Expecting nothing but swift death in the jaws of a sea beast, Vante instead finds himself face-to-face with an intelligent, inquisitive god who rejects the cruel dogmas humans have built in his name. United by a mutual desire for freedom and an insatiable curiosity about the unknown world beyond Kushinada's waters, the sacrifice and the deity forge an unexpected alliance. Together, they embark on a high-seas fantasy adventure that will challenge corrupt traditions, uncover hidden truths of the world, and redefine what it means to be chosen.
