Ґендзо

Genzo's pinwheel inspired Nami's new tattoo--a pinwheel to represent him with a tangerine to represent Bellemere. After Nami sails off with Luffy and crew, Genzo says he no longer needs his pinwheel, placing it by Bellemere's grave. The origin of the pinwheel is then revealed. Bell-Mere said that Nami cried when she saw Genzo because he looked scary, but then Genzo put his pinwheel on to make Nami laugh. It is revealed later in the manga that Luffy is very interested in the pinwheel (this inspires a new attack for Luffy, Gomu Gomu No Pinwheel), not even noticing the Navy who are trying to find Nami, just Genzo's pinwheel. However, this could be a put down in reference to Luffy's simple-mindedness.

He threatens Luffy that if he finds out that he made Nami cry, he'll come after him. However, Luffy lived up to that promise, as Nami's sister, Nojiko pointed out.

Genzo appears again later, and is outraged by Nami's wanted poster, wherein she is in a bikini, saying she'll get more suitors than bounty hunters, yet has blown it up poster-sized hanging in his house.
