The New World, in uncharted waters.
The Thousand Sunny sailed steadily across the sea.
The Straw Hat Pirates gathered on deck, every eye fixed on a Den Den Mushi.
When Werther said he had a "welcome gift" for the Straw Hat Pirates, everyone looked toward Momonosuke. Something was wrong with him.
After being injected with magnetic hormones, Momonosuke had turned into a little girl.
At the sound of Werther's voice, Momonosuke curled up to one side, trembling violently.

Luffy screamed too and instinctively stumbled back a few steps.
"Luffy!"
Usopp tried to help the fallen Luffy up, but met the same fate. Lightning spread to him
