When this painting is stolen and taken to Earth, Princess Tiara is sent to Earth to get the painting back. But a simple mission gets complicated by the fact that the painting was stolen by Tiara's former lover Kagetsu, and that the painting itself is manipulating events for some mysterious outcome.
