Dive into a world of creativity!
On Luffy's birthday, I wanna remind all of you that one of the things that makes him one of the most influential and ground-breaking shonen protagonists is that he makes things happen. No fate or prophecy or destiny leads his path. He's the one choosing, freely, what he wants to do and he will do it. And in consequence, he makes things happen in the manga that affect everybody around him. The story doesn't tell him what to do and instead, he is the one telling how the story should go. That and the fact that his whole character is meant to spread the message of following your dreams and living with laughter and joy are the reasons why celebrating his existence is so important to so many.
