Haruka

Haruka lost her mother to a terminal illness at a young age and continued living with her father, whose constant work contributed to an emotional distance between them. Her mother had given Haruka a hand mirror that she treasured, but after the death Haruka gradually forgot about it and eventually lost it. Haruka goes to a local shrine to pray for the mirror's return, where she encounters a small masked creature and secretly follows it to the land of forgotten items.
