At a haunted spot where supernatural beings gather, the ghosts Shinobu and Sayuri meet a small, white, fluffy presence.
Unable to leave the still-young stray on its own, the two decide to live together with it.

Like clouds, they lean close, play, and laugh together day after day—.
But joyful times do not last forever.

What remains after the sorrow is a warm feeling that they can always meet again whenever they look up at the sky.
