Ringston World University of New York is a prestigious college devoted to teaching geniuses from around the world. It has the top 2,000 students of the world. Of course, in such a high end and expensive place, there has to be someone taking care of it. This job falls to Karen Whitten and 6 other janitors. Karen, or Keys, is a 19 year old girl who wants nothing more than to for once not have to worry. Not about money. Not about her apartment. Especially not about her future. Little does she know, that all this and more are coming to her in a package called Nexas.
