Hibari is a Marine Commander and a SWORD a member. She is a highly proficient sniper, wielding a rifle for combat. She holds incredible long-range support abilities, being capable of disarming a whole crowd of gunmen while undetected. She uses Vegapunk’s gunpowder-modifying GP Flower technology, Flower Bullets, allowing her to neutralize enemy guns by jamming their barrels with blossoming flowers.
Hibari speaks the Hiroshima dialect, wich is inevitably lost in translation. The only other character that uses this dialect is Akainu. Considering only these 2 characters speak the Hiroshima dialect in One Piece, Oda might be implying Hibari is Akainu’s daughter or something.
Hibari’s speech style is confirmed to be the same as Akainu in Chapter 1080 as well. That would really raise her importance in the story but also add a layer of depth to Akainu as an antagonist, if he has a family/child he’s fighting to protect too. I always hoped we would get a more detailed backstory or reason for why he’s so intent on following Absolute Justice. Could be his wife was killed by pirates or something.
