Nigeratta of One Piece

Nigeratta and his wife took Robin in for a short time after Robin escaped Kanezenny. Nigeratta and his wife treated Robin well and also had to admit that she was a good child. However, one night when they thought Robin was asleep, they discussed turning Robin over to the World Government, otherwise it would be too dangerous for them and they could also get a large reward. Robin fled the same night, which upset Nigeratta so much that he even went looking for her armed with a pistol.
