Nintama Rantarou Movie: Dokutake Ninja Tai Saikyou no Gunshi

Synopsis

Rantaro, Kirimaru, and Shinbei are far from being excellent ninjas. Training at an elite ninjutsu academy in historical Japan, they are accompanied by their tongue-in-cheek friends, ninja masters, and idol senior ninja trainees. Rantaro and his ninja-in-training pals are called "nintama" — a combination of "ninja" and "tamago" ("egg"). The story of the film begins when Doi-sensei disappears after being challenged to a duel by Moroizumi Sonnamon, a tasogaredoki ninja. While Yamada-sensei and the 6th graders of the Ninjutsu Academy search for Doi-sensei, a man dressed in white suddenly appears at the Academy!
