Miyuki (Yuri Nanami) is a young Japanese woman who comes to the United States to study at a language institute; she may speak two difficult languages, but doesn’t know you can’t use a porcelain figurine for a hammer.
Two important points are conveyed in the first few minutes of Miyuki. One is that Miyuki does not want to talk about her family; the other is that there is friction between the host father and teenage son Liam (played by Barclay Iversen).
We learn that Dad (Joe Amos) had been cheating on Mom (Linden Young), and Mom attempted suicide. There is a fourth member of the family, baby Ashley. It seems apparent that Dad is having lecherous thoughts about his houseguest—or is it the other way around?
Soon after Miyuki’s arrival, she meets Edward (Matthew Magennis), a developmentally challenged teenage boy in the neighborhood. Edward spends his day doing yard work. While cleaning the kitchen, Mom spies something odd out the window. She goes to investigate, and finds her little dog Scruffy butchered in the pool. Scruffy’s is the first body to fall. Did Edward do it? Did Miyuki?
Miyuki does not take rejection well. Or jealousy. Or dinner. She’s also not the person you would want bathing your baby.
Miyuki is relatively straightforward, except for the part about a girl whose remains were placed in a temple in 1609, along with a knife her family had given her for protection. In 1948 someone removed that knife from the temple, thereby disturbing the peace of the dead girl. Somehow this ties in with modern day Miyuki, but we’re not exactly sure how. Perhaps Miyuki is not actually a sociopath who murders everyone whom she sees as a threat. She doesn’t seem possessed, but what form does possession by a 400-years-dead little girl take?
