Noelle's got some big problems - her parents both die suddenly in an accident and the only person she's got in the world is her long-lost stepbrother Shuichi, who rapes her on the night of their funeral and then ships her off to a strange boarding school where he enslaves her as his personal spy amongst the student population. He also gets plenty more ass while he's there working as the hot new professor. He's mainly taken the job to get information out of the students and faculty that might lead to the reason why their parents died (hint, it's not really an accident!), and his interrogation methods are often quite horizontal in nature. Solid animation and a good story will satisfy fans and leave them wanting the next volume.
