A mysterious young swordswoman named Amy joins his crew. She carries a sword etched with ancient symbols, seemingly bound by countless threads to a legend called the “Oath of Dawn.”
When the two sail to a mysterious island, they discover a secret hidden there that could determine the fate of the world.

As their adventure deepens, they gradually realize that the “Oath of Dawn” is more than an ancient legend: it concerns the balance of the entire world. Their choices will determine whether the dawn can truly arrive.
This is a story about courage, friendship, and duty. Follow in Luffy and Amy's footsteps as they write their own legend across the vast, churning seas, uncover the truth hidden behind the “Oath of Dawn,” and bring new hope and light to the world.
