Musical Nintama Rantaro's 13th installment's ninjutsu academy school festival.

Welcome to the stage play "Nintama Rantarou" ~Bright, Fun, Joyful!~ This is a new Nintama stage production. There's no spectacle like in "Nintama Rantarou the Musical." The play depicts the everyday lives of the Nintama. Laughing, fighting... Behind the constant major incidents that occur, there lies a heartwarming everyday life like this. Even their arch enemies, the Dokutake Ninja, aren't fighting all the time. With a relaxed attitude, the Nintama enjoy school life at Ninjutsu Academy, a ninja school that is, in a sense, a paradise in the midst of the Sengoku period. A "bright, fun, and happy!" world, just as the title suggests, unfolds. If you can feel warm and fuzzy as you peek into their slightly laid-back daily lives, both the Nintama and the Dokutake Ninja will be just a little happy.

The school principal suddenly came up with an idea and suddenly decided to hold a cultural festival. Immediately, they started preparing in a hurry, mainly with the 6th graders, but they didn't have the time or the budget! What will they do at the cultural festival!? Fourth graders, fifth graders, and teachers can't agree on anything at all! At that time, the school principal came up with an idea, so now that’s tough! Can they really do that!? The 13th Ninmyu, in which seniors and juniors work together to create a wonderful school festival, is a lot of fun!! Come on! Grab your invitation and go to the Ninjutsu Gakuen's school festival!
