The Seven Seas are dying. Coral turns to ash. Fish vanish from the waters. Crops fail. Chosen by the ocean, Bakugo and his crew sail beyond the known world in search of the lost Heart of Creation. After countless dangers, they finally return the heart to the terrible lava goddess guarding the edge of the world. But when the monster disappears, something impossible emerges. Not a beast. Not a villain. A lonely goddess. A woman made of moonlit water, ocean foam, and living wind. The creator of the seas. And the first thing she sees after centuries of suffering is Bakugo Katsuki.
