Nintama Rantarou no Uchuu Daibouken with Cosmic Front☆Next

Rantarou, Kirimaru, and Shinbei leave the familiar routines of ninja school behind for adventures that stretch far beyond Earth. Guided by questions about the night sky, the three friends explore the science behind planets, stars, gravity, space travel, and other mysteries of the universe.

Their usual curiosity and comic mishaps turn difficult astronomical ideas into discoveries they can experience for themselves. Each new destination gives the young ninjas another chance to ask why the cosmos works the way it does, and to find an answer through observation and adventure.
