Rave Master tells the story of how Haru Glory travels the world with his sword Ten Commandments fighting against The Shadow Guard, an organization led by their master King that possess a tyrannical hold over the world with their Shadow Stones. During his journeys, Haru forms a team that are then dubbed The Rave Warriors, due to Haru equipping the Shadow Stones' polar opposite, the Rave Stones, upon his sword. Like a lot of Shonen series, some manga and anime fans feel Rave Master drags on and like One Piece created by Eiichiro Oda has a lot of weird and unusual character designs. Despite that, I personally love this series.
