Ninja Master

This Ninja Master (先生忍者) of the Chameleon System taught a band of children including Hammy the art of ninjutsu. Thanks to Hammy's warning that Jark Matter was coming, having mustered the courage to speak up after spotting the advance guard of Indavers, the master and his students were able to escape the invasion of their village.

Portrayal
The Ninja Master was portrayed by veteran suit actor Riichi Seike (清家 利一). Coincidentally, he had previous made a cameo appearance as another ninja master, the Former Last Ninja, in Shuriken Sentai Ninninger.
