The theory of Akainu assisting SWORD, a secret special force within the Navy, has emerged since One Piece chapter 592, when Akainu was tending his garden. At that time, Kizaru was holding a cup and looking at the trees with interest while he was shirtless, revealing the tattoos on his body.
There is a tattoo that has attracted everyone's attention, which is a sword on the arm of the naval admiral. Not only that, Kizaru's relationship with Hibari, one of the members of SWORD, is also a topic of interest to fans, because the two have quite a lot in common.
The new Vivre Card set has revealed information about Hibari, fans discovered that her blood type and place of origin are similar to Akainu. Vivre Cards serve as useful information pages in a One Piece data book, containing important facts about certain characters.
A popular One Piece account on Twitter shares: “The more information that comes out, the more basis there is to confirm the theory that Hibari is Akainu's daughter.
– They both speak Japanese in the Hiroshima dialect (there are only two of them in the entire One Piece world).
– Both come from the North Sea.
– They both have blood type F.”
Fans had mixed reactions to this news, as most of them tried to understand Akainu's future role, while others believed that these similarities were just a coincidence.
One of them speculated: “Akainu is the anonymous leader of SWORD. There is no way this guy would let demons run the government without a plan to eliminate them for the sake of justice… Aokiji is an undercover agent. The admirals betrayed the government government. Kizaru feeding Luffy is further proof.”
“I mean having the same blood type doesn't really mean anything. A child can have a different blood type than their parents”another person suspected.
Someone expressed: “This would also strongly support the theory that it was Akainu who created SWORD as a means to circumvent the Five Elders' orders.”
Although the manga has not yet shed light on this matter, the information provided in the Vivre Card is enough to connect the events. However, for now it's just a hypothesis, which the manga may soon reveal in the future.
