Asagiri Yohko is an ordinary high school student, and she is in love with a boy who does not know it. To help things along, she has written a song to explain how she feels but that song has quite a bit more than a couple of good bridges. <br><br> Yohko learns that while she is listening to her song, she is transported to Earth's other-dimensional sister world "Ashanti." This song has the potential to open a gateway between Earth and Ashanti wide enough for a conquering force to invade and take over. And it is exactly why it was forbidden eons ago by the legendary warrior Leda who saw this coming.<br><br> This Leda warrior's duty now falls to Yohko and some newfound friends to stop the onslaught and return the 2 worlds in balance. <br><br> Maybe Yohko is not so ordinary after all. <br><br> (Source: AnimeNfo)
