A post-apocalyptic road movie that treats decay and beauty like they're the same thing. The animation doesn't just look expensive, it moves with purpose, every frame of collapsed Tokyo reminding you that the world ended, and these two are walking through its corpse anyway. Maru and Kiruko's relationship develops so slowly, so quietly, that by episode three you realize this isn't about reaching Heaven. It's about whether two people can keep each other human when everything else is rotting.

Fifteen years after a catastrophe wrecked civilization, Japan lies in ruins and man-eating monsters stalk what is left. In Nakano, Kiruko, a girl who takes whatever odd jobs come her way, agrees to the last request of a mysterious woman on the verge of death: bring a boy named Maru to a place known as Heaven. The two cross the remains of Tokyo together, each driven by personal reasons and weighed down by painful pasts. Elsewhere, behind protective walls, robots raise a group of children in a calm, sheltered facility, and a few of them start to wonder what lies outside. Blending adventure, mystery, science fiction and thriller, the story asks whether Heaven can truly be found.
