Faust succeeds in defeating Petersburg, one of the six cities on Terra II, and his sights are set on Japoness. Otaru, carried away by thoughts of being a hero, agrees to the shogun's request to sneak into Gartland to destroy their main computer. Fearing that war will make her lose Otaru, Lime foolishly sets off by herself.

Faust and Ieyasu explain to Otaru that the only way to stop the Mesopotamia is for the three maiden circuits to act as a replacement for Lorelei. However, the only way of reaching it is by combining the Japonessgar and Gartland's Sabbelburg 2. Not wanting to lose the marionettes, Otaru instead opts to head there by himself to destroy the ship and save Lorelei.
