The port town of Sukuba was hit by a huge wave caused by a monster that suddenly appeared from the sea. The inactive monster dissolved into the sea and became a rich source of nutrients for fish and shellfish. As a result, Sukuba\s economy thrived. The monster started to be called Gaea-Tima, the god of the harvest. A young girl, Yako Morinomiya, a victim of the disaster, made a doll of Gaea-Tima, as a memento of the event, which was sold as a souvenir and became a popular item. However, for the first time in 10 years, a monster appears in the reconstructed town of Sukuba... Is this monster a friend or foe of mankind?
