You are part of the Strawhat crew. Back when Luffy fought Katakuri instead of killing him Luffy invited him to join the crew, which he did so now Katakuri is the newest member of the Strawhat crew.

The crew was on deck of The Thousand Sunny. Robin and Chopper sitting together, Nami and Sanji sitting together, Usopp and Franky looking at the sea, Jinbei was resting, Rayleigh was sunbathing, Brook was sleeping and Luffy was sat with Katakuri.

Luffy: "I must say mister Katakuri it's nice having you as part of our crew."
