A girl arrives on an island carrying her father's unfinished words, and the supernatural creatures she finds there aren't here to comfort her, they're here to teach her how to let him go. Every frame breathes with the kind of animation detail that makes you pause just to watch how a character's shoulders move when they're trying not to cry. The movie knows that grief isn't a problem to solve, only a landscape to walk through, and it walks beside you the whole way.

After her father's sudden death, eleven-year-old Momo Miyaura leaves Tokyo with her mother for the old family house on a remote island in the Seto Inland Sea. She's reluctant, disconnected, troubled by an incomplete letter her father left behind. Just two words stare back at her: "Dear Momo..." The rest remains unwritten, a question she cannot put down. The island feels frozen in time, with weathered wooden buildings, fields cut into steep hillsides, shrines tucked among the trees and not a shopping mall in sight. When she finds a worn picture book about youkai in the attic, odd things start happening around town, and three troublesome youkai turn up in her life. The film is a supernatural drama about a girl struggling to adjust to a strange new home while she tries to make peace with her father's unfinished letter.
