Oki Megumi

Oki was thought of as a plain and quiet person, only to turn out a cocky sadomasochistic lesbian girl who is at first very aggressive about humiliating Alice. Once she is defeated and taken to Yoriko's home, though, Oki is happy to be a devoted slave to Alice. Although Oki's still a pervert, she's very caring and tries not to act too forceful and disconforting around her new friend. Really, Oki's intentions seem almost tame in comparison to the other people poor Alice comes across through the story... until it turns out she hasn't changed much after all and still plans to take Alice's virginity through some very questionable methods. Oki was abandoned by her parents at a very early age and left to die, but she was rescued and sent to an orphanage. She developed strange cockroach-like powers which eventually caught the attention of the Organization. At some point she became one of Kabutomushi's students.
