His name is Ranmaru Hibikiya. Today is his first day at Asao Private School...
His uncle is the dean of this school. About a month ago, he paid him a visit and offered me enrollment at his school. Seeing that he's been out of school for a long time, he accepted his offer. What was the catch? He asked me to keep an eye out for him. Bluntly, he was to be his spy...No problem.
Well actually, there was a problem. Once he arrived, he started noticing some disturbing things. There was violence and misconduct happening on campus, not the usual past times at a private high school. As he got deeper into the investigation, he came across a possible correlation between an underground society and the unusual behavior of his peers. He realized he could not trust ANYONE.
There's just one last thing...After transferring, sometime between all the sexual escapades happening on campus, and his investigation, something horrifying happened to him.
