A 9-year-old kid walks into a dying world and becomes the only thing standing between gods and extinction. The OVA strips away the mecha bloat and burns straight through to what made the original series matter: a child's unshakeable belief that friendship is a weapon stronger than any magic. Nobody can find this anymore, which is exactly why it matters, three episodes that finish a story without wasting a frame, where every bond Wataru forged in the previous series gets tested against actual annihilation.
Nine-year-old Wataru Ikusabe wakes up in Sokaizan, a divine realm teetering on the edge of collapse. Chosen by forces he doesn't fully understand, he's thrust into a world where gods and humans coexist, and where the balance between light and shadow is crumbling. Wataru has no special powers, no warrior training, and no real reason to be the one everyone looks to for salvation. What he does have is an unshakeable determination to help those around him. As Wataru ventures deeper into Sokaizan, he forms genuine bonds with the natives he meets. These aren't just convenient allies; they become his closest friends, people who believe in him even when the odds seem impossible. The friendships he builds become his real strength, a counterweight to the darkness spreading across the land. Time works strangely in this realm, stretching and bending in ways that make every moment feel urgent and eternal simultaneously. This is a story about a kid learning that heroism isn't about being chosen for power. It's about showing up for people who matter to you, even when you're terrified.
