A series of educational collaboration specials between Nintama Rantarou and the documentary show Cosmic Front Next where Rantarou, Kirimaru and Shinbei learn about space.

Rantarou, Shinbei and Kirimaru are ninja apprentices in the Ninja Gakuen, where first grade ones are called "Nintamas" (contraction of the words ninja+tama (egg)). They must learn everything a ninja must know, but as for our heroes, money, food or playing are more interesting. The series show the everyday adventures of our heroes, segmentated in a cartoon fashion, like 2 small episodes in a 30-min show. The cast also includes the teachers (Doi-sensei and crossdressing Yamada-sensei), nintama kunoichis, evil guys (Dokutake ninjas) and even family members of all the cast...
