A One Piece theory that is pretty popular in the Japanese fanbase is about Fleet Admiral Akainu’s daughter.
The theory is that the Marine Commander and member of Sword — Hibari is actually Akainu’s daughter.
If you don’t remember Hibari, she was introduced in One Piece Chapter 1061, pleading to Rear Admiral Prince Grus to save Captain Coby.
The basis for this One Piece theory is Hibari’s Japanese speech style. Hibari speaks in the Hiroshima dialect, the same as Akainu. Another thing to note is that no other character in the series speaks in this dialect.
I know it’s a far-fetched theory, but to be honest, that’s how all One Piece theories are. Oda likes to foreshadow using minute details like this. That is why the One Piece community and theorists are always on the ball with this kind of stuff.
I read this One Piece theory on the Twitter account of a Japanese One Piece fan, Sandman. Here is his Tweet:
If this theory is true, can you imagine Akainu’s daughter trying to save the man he almost killed? If Hibari is in love with Coby, this will create an interesting dynamic between these characters.
In One Piece Chapter 1071, Garp goes to pick up Helmeppo from the G-14 base to sail to Hachinosu and save Captain Coby.
And in the last panels of this chapter, we see Helmeppo and Hibari crying with joy that Vice Admiral Garp is here to save Coby. If Hibari also joins Helmeppo and Garp, and we see more of her, this could give a little more prominence to the theory.
Because why would Oda spend his time on a new side character that has no relevance in the future? If he spends more of his panels on Hibari, then he certainly has something in mind for her.
Yes, the theory is still pretty far-fetched, but still interesting. If Akainu has a daughter who ends up going against him in the future, will he be able to carry out his brand of Absolute Justice? This conflict could add a lot of depth to Akainu’s character.
