An unknown energy sends Kiriko to the edge of the galaxy called "Horse's Mouth", where the people of the disappeared planet Quent live. At the bottom of the valley, in the village of Le Shaco, a baby is about to be born, and if it is judged to be the child of God, it is a rule that it must undergo further approval at the temple of Gomor. Tribal leader Tedaya is wary of attacks on the way and requests Kiriko to protect him.
