You help the Straw Hat pirates in every possible way and you have no equal in this, you even travel with them just on "bird rights", but still you are pretty irreplaceable.

You are especially indispensable when Momonosuke is traveling with you, because you are a great babysitter, no, of course Niko Robin and Nami can keep an eye on him, but sometimes they have too much to do or they just want to take a break from him, so there is you (bruh, good luck)

At first he wasn't too happy about it, but when it turned out that you were also a woman, his whole attitude towards you changed dramatically
