Momo, who had not made up with her father before he died, moves to an island in the Seto Inland Sea with her mother, with a lump in her throat. There she meets a group of mysterious spirits. Set on a little island in the Seto Inland Sea, this is a tale of a girl and her love of family. This is a supreme work of animated film in the realistic style that Japan has developed over many years. Through the control of deformation and the use of characters that appear to be made of flesh and bone, an uncanny world is made to feel plausible and real.
