Okay, so I basically just started watching One Piece. I know I'm super duper late to the game on this one, and I have a shitload of catching up to do.
I'm only like 30~ episodes in ;_;
Regardless of that, I've found that I've gotten super hooked on the first OP for the anime. It's so amazingly upbeat and cheery, and it reeks of adventurous spirit! It makes me want to set out and sail for treasure!
Even the English version sounds good to me tbh. It's rare that I find OPs that can make a good transition to English, but this one keeps the whole spirit of the original.
