One Piece Opening 13 “One Day“ 1080p [Creditless!!!]

One day is the thirteenth opening of the One Piece anime series sung by The ROOTLESS. It first aired on July 18, 2010. In contrast with all of the series’ openings up until now, One day shows a more “serious“ or less colorful kind of music. This could be attributed to the somber events that occurred during the Marineford Arc. [One Piece Wiki] Thanks for watching, soon there will be more videos ;)
