Age: 14-15 Birthday: July 20 Height: 159 cm Weight: 48 kg Abilities: assassination, people reading Favorite subject: English Least favorite subject: science Favorite food: sushi Hobby: researching He is one of students in Class 3-E. Nagisa is seen as one of the weakest students in the class due to his small stature and mediocre physical abilities that are comparable to some of the girls in the class. However, he is actually the most talented to become an assassin out of all the students, something that acknowledged by Korosensei and Karasuma. He is able to draw closer while hiding his bloodlust to make a surprise attack and able to make his opponents falter through his bloodlust alone. Nagisa usually writes Korosensei's weaknesses that at first seem minor (since it doesn't look like major weaknesses), but eventually revealed to be useful since once they're able to almost kill Korosensei because of one of his weaknesses that is the same as the one that Nagisa has written down in his note. Outwardly friendly and polite to his friends and everyone, he hides a somewhat darker side of him as an assassin that won't be able to be found out during daily classes and will only shown during training and assassination time. According to Karasuma, whenever Nagisa unleashes his killing intent, he isn't training and truly goes for a kill. In the end he is the one who bears the burden of killing Koro-sensei.
