Eren's twin

Mina Yeager was abandoned when she was a baby, because her parents didn't want another child and thought she was an alien. She had long, lavender hair and white eyes. She was then taken in by somebody else, but all of her childhood memories have been taken from her. So then, she was just a criminal nuisance. Until she was captured by Commander Erwin, and trained to go to the Survey Corps. However, she had to join the 104th training group.... and met some people she would have rather forgotten.
