Shota Aizawa is a Pro Hero and the homeroom teacher of U.A. High School's Class 1-A. Shota is a very stern and reserved man who has lofty expectations of his students. He is primarily motivated by logic and does not believe in the necessity to maintain a clean-cut appearance or filter his words or ideas for others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations, preferring to take naps in his sleeping bag instead. As a teacher with notoriously high expectations, Shota is known to expel students who he feels are not suited for U.A. High. However, this high expulsion rate is only on paper and he re-enrolls the students he expels: Shota does this so they can experience "death" once, giving them an experience that drives them to push even higher. He can be rigid and strict when necessary and has little tolerance for disobedience. Shota is not afraid of putting his students through rigorous training and often pushes the more unpleasant parts of Heroism so that his students can overcome their limits. Shota has proven to be very vocal and unafraid when expressing his ideas. He is also known for lying to his students to manipulate them into giving their best. Despite his apathetic traits, Shota genuinely cares about his students and will go to great lengths to protect them. He has also expressed belief in his students on multiple occasions and is confident that even the likes of Katsuki Bakugo would not be swayed by villains. Despite his personality, Shota has shown on several occasions that he is not completely devoid of joy or humor: he often grins whenever he is impressed by one of his students or after he tricks them with one of his 'rational deceptions'.
