Twin?

Adam felt frustrated as he walked to the office of his adoptive mother Margarette. Not only did he make a fool of himself, he did so in front of Kurumi Ichika. While he was thinking of how to mess with the Sekiko students he was now in front of the door to his mother's office.

Adam was startled awake by the aura coming from within the room. He wasn't even in the room yet but he already felt like he was suffocating. Adam tried his hardest to remain standing but he was about to kneel, it was at that moment the voice of his mother sounded from beyond the door. 

"What are you doing my son, why haven't you entered yet?"

"I apologize for making you wait."

Adam opened the door to the office and sitting there with a smile that was not a smile was a beautiful woman who looked to be in her late twenties. That long raven hair and deep red eyes this was the one who was called a witch and a madwoman of the battlefield Margarette Brook.
