Summer is almost over and Sasshi learns his close friend Arumi is moving soon. To make matters worse, recent developments have put many of the local shops out of business and a new shopping area is on the way. There seems to be something behind it, but Sasshi and Arumi soon find that they aren`t in Osaka anymore, and instead, have suddenly been transported to a strange and magical world.

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.

It seems that the goblin just can't get things right. Another attempt to send Arumi and Sasshi back home finds them now in Hong Kong, and Sasshi is enlisted to train and be a part of an upcoming tournament. He may not know martial arts, but he'll have more than enough knowledge by the time this is over. Now, if the goblin could just get things straight, this would all be over.

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.

Now, Sasshi and Arumi are in a new version of their home that has a vibe very similar to 1930's gangster films, but they both end up working on opposites sides, unintentionally of course. Just like everything else, things aren't always what them seem, especially when it comes to killing.

There aren't any wacky themes here. Instead, it's a more somber look at how the magical shopping arcade was born, as told from those that were there some 50 years ago. It doesn't explain what's going on in Arumi and Sasshi's case, however, but it reveals some other important information.

Sasshi thinks that finally he and Arumi might have made it back to their world. That is, until he notices all of the cute high school girls wandering around in droves, and it's at that point he realizes that they have managed to find their way into the real life equivalent of a dating simulation video game. Sasshi of course couldn't be happier, but things aren't so good for Arumi, who has been transformed in a goblin (and is much shorter than she'd like to be), and that's just one of the many things that are infuriating her.

Arumi has left Sasshi out of pure frustration; probably because she looks like a goblin and probably due to the fact that she's grown to over 50 feet high, but that's beside the point. Eutus, however, has agreed to help Sasshi get back home and reveals the truth to him, as well as their karmic connection. He decides to allow Sasshi to become a Onmyou apprentice, but the help he's going to receive from Eutus is going to be more than minimal.
