The wildly popular Nintama Rantaro anime is based on the Rakudai Ninja Rantaro manga by Soubee Amako. 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!

Based on the 2013 spin-off novel written by Kazuhisa Sakaguchi, Nintama Rantaro is lively, colourful and great fun for families, anime and manga fans and aspiring ninja kids!
