Tenchi Muyo crossover. While all lost and asleep in a forest, something falls from the sky and disturbs Ryouga's sleep. He goes to investigate, only to regret it later on.

Ranma finally finds what appears to be a cure. However, things don't go as well as he has hoped, and he learns that there are things humans should never tamper with.

Two unfortunate souls have the unfortunate luck to be torn from their homeworld and appear in another. Of course, they happened to appear directly above a cursed ground. Sucks to be them, don't it?
