Flying Phantom Ship

Hayato (Masako Nozawa) has lost his parents to a giant robot that flattened his city, and all he has left is his dog and a single thought: find whoever owns the Phantom Ship and make him pay. Hiroshi Ikeda follows the boy into the house of Chairman Kuroshio (Akio Tanaka), the man leading the fight against that ship. Hayato wanders into an underground passage there and finds that what he has been told about the attack is a lie.
