It drops you in a town where feeling anything literally cracks you open, then dares you to feel anyway. Mifuse is frozen mid-winter after the steelworks blew, nobody ages, nobody changes, and when a resident's heart moves too much, fissures spread across their skin until the Sacred Machine patches them back to normal. Masamune keeps sketching in secret because his drawings are the only thing in town still allowed to change, and Mutsumi walks him into the fifth furnace to meet a girl who eats with her hands and howls like a wolf. Mari Okada writes teenage want with zero embarrassment, sweaty and petty and unflattering, and MAPPA renders it in snow, rust, and furnace-glow that earns every frame. It stacks up more ideas than it resolves, which is exactly why people bail. The ones who don't are still hearing Masamune say the name Itsumi.
A town sealed shut by catastrophe, where time has stopped and change is forbidden. Masamune exists in this suffocating stasis alongside everyone else, waiting for a normalcy that may never return. When his enigmatic classmate Mutsumi pulls him into the depths of an abandoned steel mill, he discovers a silent girl with feral eyes, someone who shouldn't exist in this frozen world. Her presence breaks something fundamental. What follows isn't salvation but chaos. The accumulated desire of teenagers desperate to feel alive again begins to warp reality itself. Love becomes dangerous, transformative, destructive. Masamune finds himself caught between worlds: the sterile order of the sealed town and the wild, unpredictable force unleashed by genuine connection. This is a story about what happens when isolation cracks, when the suppressed needs of young people collide with impossible circumstances. Beauty and ruin blur together as the characters grapple with whether breaking free means saving themselves or destroying everything around them. A haunting romance wrapped in supernatural dread.
