Koro Sensei Cosplay
It was revealed that he was raised in an environment “where everybody could easily betray one another to the point that one could only trust oneself”. Through these hardships, he decided to become an assassin in order to survive. Despite he gained an apprentice, he only saw him as a tool for his goals, which caused the latter to finally betraying his master.
However, after meeting to Aguri Yukimura, he finally know what compassion really was, becoming much more kind and compassive. According to Aguri, if he was born in a peaceful country, his personality would be “someone a little perverted, with a good head but a few screws loose, petty about small things, and also a lot stubborn… or something like that.” He has/would have “a gentle smile not just for business, but because he is a gentle person himself.” This prediction happens to reflect his personality which became forefront after he answered the tentacles.
When first introduced, Korosensei was a jovial individual who demanded absurd and seemingly mundane requests despite claiming he would be the cause of the planet’s destruction in a year. He was also rather kind to others in general, and could switch from silly and childish to serious on the fly. According to Nagisa, Korosensei also was unintentionally petty at others at times and loved gossip, both traits heavily noted through the series.
Korosensei deeply cared for his students’ emotional and physical well-being and would lose his temper whenever any of them were put in danger, even by one another. On the annual school trip to Kyoto, a few of his students were assaulted/kidnapped by a gang of high schoolers hidden in an alley. After searching the entire area painstakingly, he infiltrated the abandoned building where two kidnapped students were being held at and single-handedly beat up all of the high schoolers and scaring them away.
One of Korosensei’s attributes was the fact that he was able to connect to each student individually, being an objective, empathic, and observant person who will do almost anything to help his students. This was the reason why all the students respect him despite the fact that he was going to blow up the Earth in a year. Taking care of each student’s needs, Korosensei would sometimes be piqued by a student’s current problems or interests, and would try his best to guide the student along or solve it for them.
