Story description:
In Japan, young Masashi moves from an evacuation center to a small town after an earthquake/tsunami. There he discovers that every child has a fantastical monster-like creature that they can communicate with. But soon he learns that these creatures are being used in an evil plan to collect negative energy from children.

A little bit of a weird movie with a strange mishmash of genre's/concepts, but the kids and the monsters are fun and interesting.
