Shiba Roses, the "Sword Saint", was the very first Rave Master. He had fought in the war against the mother of all Dark Bring, Sinclair, fifty years ago, and had embarked on a journey to gather the five mystical Rave Stones that went missing since. He eventually transferred the responsibility of defeating all five Dark Brings (Shadow Stones) to his successor, Haru Glory, the second Rave Master.
