Rave Warrior was the Shinobi, who fought against and Sealed Ten-Tailed Slider Many Years Ago.
A Long Time Ago, The Peacful Kingdom of Garaten was suddenly transform into chaos and pain by the Powerful Slider. To counter the slider, God bestowed the Rave Warrior the powerful armor and the Rave Warrior was instructed to use the sword against the evil one. Thanks to the Power of God, The Ten Tails was weakened and sealed deep with Miharu no Mikoto to never rise again by Rave Warrior's Courage.
The Rave Warrior's Appearence was similar to Yuki from Last Blade and Haru from Rave Master Series.
