Suzume’s Door-Locking

Suzume Iwato encounters Souta Munakata while on her way to school, and he guides her to a nearby ruin in search of abandoned areas. Suzume becomes curious about the ruin and decides to investigate on her own, discovering a door that leads to a dreamlike universe she can sense but not access. Nearby, a stone takes the form of a cat-like creature and flees when Suzume touches it, prompting her to leave the area. Unbeknownst to her, this action releases the "keystone" and allows evil from the other universe to spread, prompting Suzume to join Souta in sealing all open doors before the situation spirals out of control.
