Having lost your grandmother, you return to the countryside after a long absence to settle her affairs.
That night, as you recall the "masked boy" who helped you in the forest during a summer festival long ago— Chikage, the leader of the Karasu-tengu clan, appears before you.
And he has never forgotten you since that day.
"The one I wish to welcome has long been decided."
A story of reunion between a Karasu-tengu and a human, beginning from a single childhood encounter.

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

Despite the strong summer sun, a quiet time flows within the carriage. Guest gazes out the window, remembering childhood days. The house of their grandmother visited every summer. The sound of cicadas. The scent of dusk. The summer festival at the shrine.

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