Starting the chapter, we’re introduced to “Urashima’s Casket,” a device that can make anyone grow older. However, a mention is about as far it as goes, since Decken needs to marry the princess first to gain access to the palace. So I’m thinking the casket will come into play later on in this arc, or perhaps even other arcs. Moving on, because Otohime was able to impress Fishman Island with her iron will to unite with the humans, she is finally able to gain everyone’s signatures. Her death scene, while not unexpected, remained shocking and was “great” in that Oda style of forced happiness in front of cruelty that never fails to move me. Just in the nick of time to become a martyr too, as if she had died previously, people would have looked at her death only in pity. Now with the inspiration from her successful contract with the Tenryuubito, legit or not, she passes on her will. Given Fishman Island’s current state, it seems her martyrdom didn’t last. The earlier “bonding” scene between the brothers protecting Shirahoshi should have been an obvious death flag, but it proved effective emotionally as the brothers fight against their tears to entertain Shirahoshi from activating her recently learned dangerous wail.
One point was made by Otohime that the mermaid that can speak with the sea kings shall be guided by a person. That really screams Luffy, but to be honest, Luffy’s got enough of a head start with all his connections already. Will of D, relation to Dragon, the King’s Haki, and encaptured the heart of supposedly the most beautiful woman in the One Piece world? Eh, I guess if Roger and his crewmates like Rayleigh can pull off so much stuff, Luffy needs to leave behind some legends of his own, as mere proof of his superiority. If he is to be the one that guides Shirahoshi, I hope it’s something he earns, rather than “destiny” makes it so.
