Henshin Ninja Arashi

Tani no Maju, a member of the Chiguruma Tou clan, created the Ninja Henshin Jitsu, a method allowing individuals to transform into Keshin Ninjas capable of accessing their inner mystical powers. He refused to share this knowledge with Majin Sai, fearing its misuse could endanger Japan. In response, Majin Sai sent a Youkai Ninja to steal the technique, resulting in Tani no Maju's death. Before dying, he revealed the technique to his son, Hayate. Fueled by anger, Hayate activates the method, unlocking his latent mystical abilities and transforming into the powerful ninja known as Arashi.
