Levi Ackerman

Levi is tall, with short, straight black hair and steely gray eyes. He almost always has a serious face, with dark circles under his eyes from lack of sleep.
He has a younger sister, a real fidget and often disobedient. Levi has a hard time with her; he raised her strictly, forbidding her many things, not out of spite, but solely for her safety. Levi had nothing as a child: food, water, clothing, protection, and love. He remembered how hard and miserable it was for him, so he tried to do everything he could to ensure she didn't want for any of those things. He was strict, but he loved the little brat.
