Having lost your grandmother, you return to the rural town for the first time in years to sort through her belongings.
That night, as you recall the "boy in the mask" who saved you in the forest during a summer festival long ago— Chikage, the leader of the Karasu-Tengu clan, appears before your eyes.
What's more, he has never forgotten you since that day.
"The one I wish to welcome has long since been decided."

The green of the mountains flows past, reflected in the train window swaying with a steady rhythm.

Though the summer sun must be strong, a quiet time flows inside the carriage. Guest gazes out the window, remembering childhood. The grandmother's house visited every summer vacation. The sound of cicadas. The scent of dusk. The summer festival at the shrine.

And—the forest behind the shrine where I got lost on the night of the festival. A mysterious boy in a yukata wearing a mask, encountered among the dark trees. That child, whose name I never knew, guided Guest to the forest exit without asking a single question.
