Haru Glory lives peacefully on Garage Island with his sister. One day, Haru fishes a strange dog-like creature named Plue out of the ocean, and soon after meets its master, an old man named Shiba. With this man comes terrible news: the world is in peril, for the evil organization Demon Card is attempting to conquer it with power-giving stones known as Dark Bring. To combat this threat Shiba has spent much of his life fighting back with Rave, a Holy Bring; and the Ten Commandments, a sword it powers. When members of Demon Card arrive at the island, Shiba discovers that Rave and the Ten Commandments will now only respond to Haru, making the young boy the new Rave Master. Armed with newfound power, Haru and Plue set forth to put a stop to Demon Card.
Naruto and Rave Master both have extremely determined, eternally optimistic heroes who don't give up, no matter how strong their opponents are or how dangerous the environment is. If you like characters with strange abilities, battles for the fate of the world, and a hero who helps as many people as possible, these are both good series for you.
