Suzume

On her way to school, high schooler Suzume Iwato meets Souta Munakata, a young man looking for abandoned places. She points him toward a nearby ruin but, curious, decides to follow him there herself. At the ruin, Suzume finds a solitary door that opens into a strange, dreamlike world-one she can glimpse but not step into. Nearby, she picks up a peculiar stone, only for it to transform into a cat-like creature and dart away. Unsettled, she leaves without closing the door, unaware of the danger she’s unleashed. Now freed, the "keystone" that once sealed the door is gone, allowing evil from the other world to spill into Japan. Realizing her mistake, Suzume teams up with Souta-who’s been working to contain these threats-to track down and shut every open door before disaster strikes.
