First of all, this is only the first of what was originally supposed to be a six-episode series. They only made the first two and never got to make the next four, I can only assume because they failed to find an audience.
Anyway, here's the story (what we get to see, anyway): Yuskae is a high school boy whose parents are dead and he is renting a shed in a land lady's backyard. One rainy day he is riding his bike to school, late as usual, when suddenly there is a strange light from the sky and a girl falls on top of him. Soon after falling, she passes out and he takes her back home. After waking up she finds she can't remember any thing, other than her name, Rouge. Yuskae does what he can to help her remember, and before long they start to fall in love. (Yes it's cliche, but still you can't help but feel for them, the way it's potrayed so well.) However, there proves to be more problems than amnesia. Rouge has come from another dimension where two other young women, Kage and Mage, claim to be her sisters and arrive at Yuskae's doorstep. Much to his dismay, they end up rooming in with Rouge and Yuskae.* What's more, it turns out that Rouge and her sisters were the royal daughters of a kingdom where there was an uprising and the kingdom was taken over, and the parents of Rouge, Kage and Mage, the king and queen, were killed. Now the villains have come into our world, and they are after Rouge.
At the end of the second (and what turned out to be the last) episode, two evil servants have been vanquished and a third one has been sent out, Rouge still has no memory, and we're left hanging, wondering what will happen next. Alas, what could have been.
*The plotline of a magical girl with an ordinary boyfriend whose two unwanted sisters come to stay with them should remind anyone who's seen and/or read OH, MY GODDESS! of that anime/manga. Also, Rouge and Yuskae are voiced in the English dub by the same two people who did the English voices for Keiichi and Belldandy in O.M.G.
