The East Blue Saga is still one of the best Sagas in One Piece in my opinion. It's when Luffy starts his journey to become the King of the Pirates and it's when Zoro, Nami, Usopp, and Sanji all come aboard to join the crew. Nostalgia runs strong here and for good reason. I love "We Are" it's one of the best One Piece openings along with "Brand New World", "Share the World", "We Go!", "Wake Up", and "Over the Top". I can't really choose which opening out of those 6 are the best because they're all so good.
