Nagisa is a calm, collected, and friendly individual. He is exceptionally observant and circumspect of his surroundings and the situations that develop around him. He tends to pay strict attention to Korosensei in hopes to understand the motives of this mysterious being and compiles the information he has gathered in his notes for reference. He's noticeably more reserved and shy then other students in his class, thinking much more then actually talking and referring to himself as "invisible" because of this. He seems to be commonly nervous about what he says in important situations, being hesitant and harboring a slight stutter. This is possibly due to his mother telling him he isn't good enough.
Despite his calm demeanor, he harbors deep insecurity about his talents and how he is perceived by the people around him. This is reflected by lack of goals and general pessimism about his own future. Nagisa also isn't easily fazed by things that would unnerve the average person as shown with his interactions with Karma and the prospect of using a real knife.
Nagisa is the son of Hiromi Shiota and her (presumably ex) husband. His mother had hoped for a daughter so she could experience all the things she had missed as a child through her, but got a son instead. As a result, she dictated his life from forcing him to keep his hair long, to being forced to crossdress and verbally abused him whenever he spoke against her. Her personality also caused her husband to leave her and Nagisa.
He was revealed to formally have been in Class D during his first two years of middle school before falling into Class E due to poor grades. During those two years he hung out with fellow classmate Karma Akabane though they slowly drifted apart. Soon after starting the new term as a Class E student, Nagisa met Kaede Kayano. She gave him what would become his signature pigtails instead of the ponytail he usually uses to keep his long hair from being less noticeable, thus beginning their friendship.
Reason For Cross-DressingEdit
Nagisa is known for his androgynous appearance, in which gets poked fun of, mainly by Rio Nakumura and Karma Akabane. Nagisa finally crossdresses in Chapter 66. He does so to go unnoticed during an assassination at a strip club that his group had to pass through. He also dresses up as a girl a few more times as the series goes on, mostly against his will. This gag had stopped as of Chapter 116, when Nakamura discovered the reason why he keeps his hair the way it is, due to his mother's oppression.
Apparently, his mother always had wanted a female child since her parents never let her live her teenage years as a normal girl. She pressed her dreams to Nagisa believing that it was the best for him, usually shouting at him constantly when he said no.
She later stopped shouting at him when he showed his killer skills and protected her, thus making her return to a gentle kind behaviour towards him. This causes his mother and father to get back together.
