His destiny takes a turn when Shiba gives him the Rave stone, passing on the powers of the Rave Master.
He first fished Plue the Rave bearer out of the ocean, and soon met Shiba, the Rave Master. Haru was chosen as the second generation Rave Master by Rave. When he realizes the true threat that Demon Card are to the world, he then promised Shiba that he will complete the collection of Rave and end all of Demon Card's evil. He then sets off to find the pieces of Rave to restore peace to the world.
He's like his father, Gale Glory, never giving up in a battle, no matter the circumstances. He is not afraid to die for the protection of his loved ones or the planet itself. Along the way, he found good friends and allies, each having their own goals, yet were bound together thanks to him and helping each other along the way. He is very friendly and has a lot of energy. He is very protective of Elie, and does anything he can to ensure her safety. Haru also shows to develop a romantic interest in Elie progressively throughout the series, as it also becomes apparent in later chapters that among Haru's greatest motivations to keep fighting onward is in fact for Elie.
