Welcome to the Space Show

Natsuki Koyama (Tomoyo Kurosawa) is one of five children left to run their own summer camp, and she is the one who pulls a hurt, dog-like alien out of danger. As thanks, he takes the group to a colony on the Moon, though the trip leaves them stranded in space with poachers trailing them and camp ending soon. Koji Masunari keeps the children close together on the journey, and what holds them is how much they depend on one another.
