As Kamon Wattana begins her third year at Korekara Academy, the school for talented but troubled young girls, she has a lot on her mind. Her supposed archenemy never really hated her. There's a new underclassman with first aid skills and an attitude that stands a chance against Kamon's own. Not to mention, the murder of Usagi Hanamura the previous year has still got some of her gang members wrapped up in what seems to be an unending, fruitless investigation. Through the year before Kamon's graduation from this strange school, she's got to balance her newfound social life with the discoveries coming to light about Korekara Academy's true nature, and hope that she can survive to that day as distrusts begin to rise against students and teachers alike.
