About Nintama Rantarō
Nintama Rantarō is set in the Sengoku period and follows the story of a ninja academy centered on the trio of Rantaro, Kirimaru, and Shinbei. The students are novice ninjas-in-training, still far from becoming full-fledged shinobi — but their everyday school life is filled with energy, laughter, and plenty of fun.
