Sensei Mugensai Hinata

Mugensai Hinata is the Ninja master of Hayate Way's Ninja Acdemy, master of animal-change Ninpou. He turned himself into a hamster to evade his pursers, but he forgot the words that that would restore him to normal and thus is referred as the "Hamster Curator" (ハムスター館長, Hamustaa Kanchou). But he can fight despite his form and communicated with Gozen before she revealed herself. Mugensai briefly returned to human form in the movie by means of a kiss from Princess Laiina, but was forced back to a hamster when she left. Eventually he returned to his human form to protect his daughter from the falling debris when their base was affected by the Evil Force. Two months after the final battle, Mugensai gives the Hurricanegers and Gouraigers a final challenge: to take their diplomas from him.
