It's the final day of Obon celebrations. The summer is hot, and the breeze quietened to a mere whisper.

Armed with only a writing satchel, and accompanied by his beloved cat Trickster and Grandpa, young Arthur undertakes an heroic journey across Japan’s remote island of Okinawa.

Along the way Grandpa shares some of his best ghost stories and Arthur gets busy writing them down whilst his imagination sets about tackling ghastly ghosts, dreadful demons, yukky Yokai and voracious vampires.
