Nagisa Shiota's is very small to be in his third year of middle school, yet, he is. As a child and during his first and second year of middle school, he was teased and mocked for his unusually long hair and small figure. He would cut his hair, if he could. Nagisa's mother is a very bossy woman. This even drove her husband, Nagisa's father, away. She's always wanted a daughter, and was furious when she had a son instead. She forces him to keep his hair long and makes him cross-dress at home. She's abusive and bossy, making Nagisa despise his own mother. When Nagisa was put into class 3-E, the assassination classroom, he began to learn what he was best at. Being an assassin. A couple months after he was transferred into E-class, something changes in Nagisa, a dark side of him showing. A side that no one had ever seen before. A side that enjoyed murder and blood.
