Rayún and Sayén, two young apprentice rainbow hunters, live in a post-apocalyptic world and must use all their strength and intelligence to capture mythical creatures called "Draguiris" (a type of rainbow with dragon-like features). The energy generated by the Draguiris is used to produce sustainable energy, maintaining a fortress they call "the Capsule," which protects them from a violent and harrowing outside world, divided into multiple tribes, each vying for dominance and self-preservation.
