すずめの戸締まり

Suzume

High school junior Suzume has no idea why the beautiful stranger she meets is looking for ruins, for a certain door. Soon after pointing the stranger, Souta, in the direction of an abandoned resort, she thinks better of it and goes to try and stop him. But before she can find Souta, Suzume unknowingly opens a decrepit door to a world beyond time and place—and stumbles into an adventure of seismic proportions. (Source: Kodansha USA)
