Tezuka throws everything at the screen like he's running out of time, alien worlds that look like nothing else, transformation rings that feel genuinely weird rather than coolly designed, a prince finding out he's nobody from nowhere. The animation moves in ways 1978 had no business achieving. The second half collapses under its own narrative weight, but by then you're already too far into Tezuka's fever dream to care about logic.
A terrorist attack tears through a spacecraft, forcing desperate parents to make an impossible choice: they seal their infant son in an escape pod and send him into the void. The pod crashes on a strange world where inhabitants command a bizarre power, transforming their bodies into animals through magical rings. The royal family discovers the abandoned baby and raises him as one of their own, a prince among shapeshifters. Years pass in relative peace until space pirates descend on the planet with ruthless intent. During the chaos, the young prince finds himself kidnapped and dragged across the cosmos to Earth, a world he's never known. Here, fragments of his shattered past begin surfacing. He learns the truth about his real parents, about the attack that orphaned him, and discovers he has a brother he never knew existed. Now stranded on an alien world with his newfound family history, the prince must navigate this overwhelming revelation while navigating the dangers that follow him.
