Rave Master, titled Rave (レイヴ Reivu, romanized as RAVE) in Japan and also known there as The Groove Adventure Rave, is a Japanese manga series written and illustrated by Hiro Mashima. The series follows Haru Glory, a teenager in a quest to find the five pieces of the sacred stone Rave in order to bring peace to the world by defeating the criminal group Demon Card. Mashima created this series with the idea of travelling around the world and was presented with difficulties in its serialization due to its considerable length.
In 0015, the world is corrupted by Dark Bring, dark stones that bestowed powerful magic with different abilities to their owners. The Dark Brings are used by the Raregroove Kingdom, and the Symphonia Kingdom fight against them with their powerful five Rave Stones. Shiba Roses, the first Rave Master, attempts to destroy Sinclaire, the "mother" of all of the Dark Brings, with the Ten Commandments Sword. However, the aftermath causes a massive explosion known as "Overdrive", destroying one-tenth of the known world. Shiba, protected from the disaster by his special guardian "dog" Plue, holds onto the Rave required to power his sword. Plue and the five remaining fragments of Rave, however, get scattered around the world.
Fifty years later, sixteen-year-old Haru Glory lives on the peaceful Garage Island with his older sister Cattleya. Haru accidentally fishes Plue up. Shiba arrives wishing to reclaim Plue, but a group of terrorists from the Demon Card organization appear to kill Shiba. Shiba tells Haru that he is the second Rave Master, entrusting the Ten Commandments Sword, Plue, and his Rave to him. Seeking power to defeat Demon Card, Haru and Plue set off on a journey to find the missing Rave stones. Upon arriving at Hip Hop Island, Haru befriends a girl named Elie, who has no recollection of her past. During their journey, Haru encounter enemies from Demon Card who eventually become his allies, including Shuda and Sieg Hart. Haru later meets a diverse group of allies, including Hamrio Musica, grandson of a local blacksmith; Let Dahaka and Julia, two who appear human but are in fact of the Dragon Race; Griffon Kato, a strange blue creature and Plue's friend; Ruby, a penguin and a casino owner; Belnika, a mage; and Niebel, Sieg's close friend. He also encounters Gale "King" Raregroove, the king of the Raregroove Kingdom and leader of Demon Card. On the Tower of Din, Haru reunites with his absent father Gale Glory to defeat King and end Demon Card. Although they win, Gale sacrifices himself to save his son from Din's destruction.
