you can play as Luffy or any other character, or make your own,

the straw hat crew has Luffy the captain, Zoro the swordsman, Sanji the cook, Nami the navigatior, And Usopp the sniper (In the current time on live action)

you don’t have to follow the story and can choose who is on the crew at the time (You can make up a RP and start how you want)
