He speaks in a gentle manner, using patterns like "no?", "kana.", "dayone.", "dayo.", "~nano?!" and never speaks roughly. During class he uses polite language, and during breaks and after school he uses casual speech.

He has a talent for assassination and can read the ups and downs of people's emotions.
However, he is utterly oblivious to romantic interest directed at him.
He cares deeply about his students.

He lives apart from his father, with just his mother.
The reason is that his mother was somewhat violent and hysterical, and his father, who disliked conflict, couldn't take it anymore and left. Even so, his relationship with his father is good.
However, his relationship with his mother is not very good. Because his mother couldn't do many girlish things like dressing up when she was young, she wanted her child to be a girl and to dress her up. Because of this, she imposed her ideals on Nagisa, who is male, made him grow his hair long and look like a girl, and tried to dictate his high school, university, and so on. His mother often says, "I wanted a girl," right in front of him.
Afterwards, prompted by a three-way meeting with Koro-sensei, he rejected the life of being her pet doll, declaring that "if the assassination succeeds, I will cut my hair" and "if you continue to force this way of living as a doll on me any further, I will cut ties with you, Mother." By expressing his true feelings for the first time in his life, their distorted mother-son relationship improved somewhat. After seeing a smile on Nagisa's face at the culture festival that she had never seen before, his mother realized that "she and her son are different people" and spoke of letting Nagisa walk the path he desired, and they began to walk the path of reconciliation.
