Thirty years ago, “Fallen Gods” and “Fallen Towers” suddenly appeared all over the world. Monsters emerged from these towers, robbing the world of its peace. However, the countless gods bestowed divine weapons upon strong humans, who then conquered the towers and purified the Fallen Gods, returning them to their original forms. These humans were hailed as heroes. Among them, the greatest of all was one of the “Three Legends,” Shotarou Kusunoki, the master of the “Sword of Purification.”

To witness his older brother’s legendary deeds up close, Hiromu Kusunoki worked as a porter, carrying supplies. But one day, his brother’s body was possessed by the Fallen God Futsunushi, and Hiromu was nearly killed. At that moment, he heard a mysterious voice coming from the Sword of Purification — it was Gayamaru, the Wild God dwelling within the blade.

To save his brother, the young man rises alongside the Wild God to reach the pinnacle of strength!
