The recent conclusion of the Wano arc has allowed ONE PIECE readers to dive into the final saga of Eiichiro Oda's masterpiece. However, instead of providing answers, the manga is raising further questions and theories through the introduction of new characters.
In chapter 1061 of ONE PIECE, a theory was born, but it has not yet been confirmed. The character introduced by Eiichiro Oda is not just any Marine but the daughter of the Grand Admiral of the ONE PIECE Marines. This theory arose due to the language used by Hibari. She speaks in the Kansai-Hiroshima dialect, a language that only she and Sakazuki use within the story.
While we do not know much about Akainu, he is a committed Marine who obtained his position by defeating Aokiji, but his age could perfectly align with him being a father.
This theory seems to receive further confirmation in ONE PIECE chapter 1081. Accompanied by Garp, Hibari and other members of SWORD go to Hachinosu to save Koby, the great hero of the Marines who opposed Sakazuki at Marineford to stop the terrible war against the pirates.
In love with Koby and opposing her father's philosophy, Hibari would have joined SWORD. But it's not just this that supports the fan theory. Another important detail has not escaped notice. Hibari is the first victim of Kuzan's ice, Sakazuki's greatest rival who left the Marines and joined Blackbeard precisely because of his defeat at the hands of Sakazuki.
With the knowledge that Hibari is Akainu's daughter, Aokiji could have sought revenge in this way.
Overall, the introduction of new characters and theories is keeping ONE PIECE readers engaged, and the possibility of Agent Sword being connected to Akainu only adds more excitement to the mix.
