Nagisa Shiota

The students of Class 3-E tried to kill teacher Koro because he is a supernatural being that threatened to destroy the Earth by March, and his students from Class 3-E were given the task to kill him in order to save the world, which became part of their curriculum and personal goals, as well as fulfilling the promise of his old teacher, and he himself took the job of a teacher to prepare the students and find a way to save himself

Nagisa is a collected and friendly person, attentive to his surroundings and the situations happening around him. He keeps a close eye on Korosensei, noticing every little detail, and keeps a diary of his own notes, hoping to understand the creature's motives and goals.

Nagisa seems to be much more reserved and shy than the other kids in his class, often referring to himself as "invisible". He gets nervous and stutters in important situations, likely due to an inferiority complex caused by his mother's words that Nagisa is "not good enough" - however, Nagisa is not particularly scared or bothered by things that would be at least creepy to a normal person. He also has occasional outbursts of rage.

Despite his calm and kind attitude towards others, Nagisa had deep insecurities about himself, his talents, and how others perceived him. These insecurities were reflected in his lack of goals in life and his uncertainty about his own future, which eventually led to Nagisa being transferred to Class 3-E. However, Nagisa eventually learned to respect himself and became much more objective and tolerant of his own shortcomings, and found his purpose in life thanks to the efforts of his teacher and friends.

Nagisa is a young man with blue eyes and blue hair.
