Kouichi Nagano

Uta — the most beloved singer in the world. Her voice, which she sings with while concealing her true identity, has been described as “otherworldly.” She will appear in public for the first time at a live concert. As the venue fills with all kinds of Uta fans — excited pirates, the Navy watching closely, and the Straw Hats led by Luffy who simply came to enjoy her sonorous performance — the voice that the whole world has been waiting for is about to resound.

Zephyr, now known as Z, rides the seas with only one goal: Destroy all pirates and their dreams at becoming King of Pirates. When Luffy and his crew encounter him at sea, not only are they utterly defeated by the man with an arm made of Seastone, Nami, Robin, and Chopper are turned 10 years younger due to Z's minion Ain. Luffy is so determined to win against him that he does not even notice Z's master plan that could sacrifice thousands of lives.
