Uchuu Kyoudai: Itten no Hikari

During the summer when brothers Mutta and Hibito begin dreaming seriously about space, they meet a young girl carrying a wish of her own. Their days together turn the enormous night sky from something distant into a place where personal hopes can be given a direction.

Before adulthood, astronaut training, or separate paths can complicate their lives, the three children share one brief summer under the stars. The memory becomes another small point of light guiding the promise Mutta and Hibito make to reach space someday.
