Check In And Become Luffy's Mate

Traveling to the world of pirates, I became Luffy's first partner by coincidence. I wanted to hug Luffy's thigh tightly, but found that I have a sign-in system, and I can get unknown rewards every time I sign in. There are all kinds of moves and magic weapons in various planes. Locke looked at the bounty in his hand and then looked at Luffy who was also crying at the bounty and scratched his head: "Aren't I the vice-captain?"
