Welcome to the chaos, Enjoy your time here.
If you like One Piece - I have some recommendations for you!
- Bleach
- Samurai Champloo
- The Law of Ueki
- Hajime no Ippo
- Reborn!
- Inuyasha
These aren't 'Pirate' anime per-say, but! They do have adventure and action implemented into them, for that kick of being similar to One Piece.
They also have a decent amount of streaming too, so you can enjoy these whenever you need to wind down. Or when you need to binge something...
I highly recommend Hajime no Ippo, Samurai Champloo, and Bleach, awesome starters to an anime journey..!
As again, welcome to the forums, welcome to the chaos, and enjoy your time here...
