A Pirate, Already a King

What? The main quest is to become the Pirate King? But I have neither the strength nor the luck, and I just want to hang on until my own story reaches its ending.

What? I can get a summon card through the monthly sign-in, and every summon card guarantees an A-rank or better One Piece character?

I'm in the world of One Piece, with no ship from the start, and all I can do is play it safe. This damn System is useless. It took a whole month of idling before it even told me I had a System. If I hadn't been cautious, I would've been killed off ages ago.
