Kubo and the Two Strings

In feudal Japan, young 12 year old eyepatched Kubo tends to his ill mother Sariatu in a mountain cave near a village. He earns their meager living by magically manipulating origami with music from his shamisen for the village folk and his mother, telling the tale of a samurai warrior named Hanzo, Kubo's missing father. Kubo is never able to finish his story as he doesn't know what happened to his father and his mother can't recall the end of the story due to her deteriorating mental state. Sariatu warns him not to stay out after dark as her Sisters (his aunts), Karasu and Washi, and his grandfather, the Moon King (who took his eye when he was a baby) will be able to find him and take his remaining eye.
