One Piece Episode 414

[Tyreal]

As the second and third in command of a Shichubuki, you have to assume that if they had bounties, they'd be around Zoro's level.

Considering that Boa's bounty is only 80 million I doubt that her sisters actually have bounties and if they do they would only be ~15-30 million.

Considering that Boa's bounty is only 80 million I doubt that her sisters actually have bounties and if they do they would only be ~15-30 million.

Her bounty, like all the Shichubuki, wouldn't be a good reflection of their power though since their bounties stop rising once they become Shichubuki.
