Nagisa Shiota

Height: 159 cm (5'2.5") Class: Class 3-E

He is one of the 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 a girl. However, he is actually the most talented to become an assassin out of all the students, something 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 seen 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 be 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.
