Shirahoshi

As the youngest daughter of King Neptune, this massive, smelt-whiting mermaid holds a significant place within the royal lineage of Fishman Island. Though initially introduced through the deceptive claims of Pappug, who promised a meeting with the Straw Hat Pirates, her presence is central to the kingdom's lore. Despite her intimidating size, she remains a key figure in the underwater realm's unfolding history and the crew's eventual arrival.
