Two girls on a motorbike moving through a dead world shouldn't feel like warmth, but it does. The show disguises existential weight in soup recipes and tinkering montages, so the devastation sneaks up on you, by episode four you're grieving a civilization you never knew, mourning people who stopped existing long before the opening credits. The animation and soundtrack don't just complement the emptiness; they make the emptiness into something worth looking at, even worth returning to.

Two girls roam the remains of a dead world on their cherished Kettenkrad, scrounging for food and fuel to keep going. Chito and Yuuri appear to be among the last people alive, and they have little but each other and the machine beneath them. They pick through old military sites for supplies and parts, and pass the time wondering what the old world was like. Solitude weighs on each of them at times, but being together makes it easier to bear. Yuuri's clumsy enthusiasm and Chito's steady calm bring small bright spots to their bleak days: a hearty bowl of soup, machine parts to tinker with, target practice, new books, and snowball fights on a frozen battlefield. Set among barren landscapes and deserted buildings, this post-apocalyptic slice of life adventure is a hopeful story of companionship in a dying world.
