SN HighSchool

During hundreds of years the world has been balanced like the ying-yang symbol. The Ying symbolized the humans while the Yang, the "nonhumans".

But as the ancient Chinese symbol, each world has a part of the other world and even if that part is small it isn't insignificant. Actually, that one part can doom the whole balance between worlds.

And it doesn´t help that the two worlds meet in a high school filled with hormones and teenage problems.
