Itsumi Midoriya viewed the world differently opposed to her brother's beliefs. She never really found the admiration for heroes, nor did she see the greater good. To put it simply, her mind was something different. People always noticed her offsetting behavior, that she was colder. She felt differently from the majority of people. Her morals were different. She was just...different. People didn't like it, and she didn't like them. Itsumi grew up learning to avoid violence, but warnings and bottling it in only got her so far. One day she just let go and snapped. That's all it took for her to see the world in a better, yet darker, picture.
