He is the pupil of Sanshinshou, the three god generals. A thousand years ago, he was deceived by Daimaou to attack humans and he was imprisoned within a blue pot as punishment. The pot was hurled into space by Daimaou. The bottle returned once the war between the Youkai and the Kakuranger was at full swing. The Kakurangers found the bottle, and Tsuruhime was the only one able to remove the golden hammer from the bottle to break it open. As a ninja master, NinjaMan wields a katana, and has a wide array of ninja-magic skills, including enlargement to aid his mentors in their fights. He has the ability to ride on a cloud called the Kinto Cloud. Whenever a Youkai calls him "Blue Squirt" or insluted in such a manner, he gets angry and transforms into SamuraiMan , who connects his weapon with its sheath to form a powerful javelin. In this state, SamuraiMan creates explosive energy spheres formed from his rage in his ultimate attack, Samurai Rage Bomber. In the finale, after the Youkai were sealed away, Ninjaman was able to go away with his masters and bid goodbye to the Kakuranger. "Partner of Justice, NinjaMan!"
