Osaka is gone, and Arumi and Sasshi find themselves in a world full of dragons and strange mythical creatures. All the familiar faces from back home are here, but with completely different personalities, and the two are suddenly enlisted to conquer an evil force.

Sasshi and Arumi believe that a strange goblin they encountered when first arriving in the Middle Ages has the power to send them home. He sends them away, but now they are stuck in a futuristic version of their home, and mecha combat may be their only means of escape.

Sasshi and Arumi thought for sure that they were going back home this time, but that`s just not to be. Instead, they find themselves in a prehistoric version of their home, complete with the usual cast of strange relatives that they have grown accustomed to seeing. But, they soon have more problems when they are on the run from the natives and trying to get a baby dinosaur back to his family.

After the troubles of the amusement park, Sasshi and Arumi are now at war. On both side of a conflict, the two armies fight for the Abenobashi Shopping Arcade. When it comes to war and cliches, its all here in the chaos.
