Uta – the most beloved singer in the world whose voice has been described as "otherworldly" – is renowned for concealing her own identity when performing. Now, for the first time ever, she will reveal herself to the world at a live concert. With the Navy watching closely, the venue fills with Uta's fans-including excited pirates and the Straw Hats led by Luffy, who simply came to enjoy her sonorous performance-all eagerly awaiting the voice that the whole world has been waiting for to resound.

The story begins with the shocking revelation that she is the enigmatic Shanks' daughter. Uta stands on the stage, with the ordinary wish of "Making the world happy with my music." There's Gordon, a mysterious character who knows Uta's past, and glimpses of Shanks’ shadow. On Elegia, the island of music, Luffy and Uta reunite for the first time since they last met 12 years ago in Foosha Village.
