Aizawa

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.[6]

As a teacher with notoriously high expectations, Shota is known to expel students who he feels are not suited for U.A. High School. However, it's revealed that this high expulsion rate is only on paper and that he actually 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,[14] although it is noteworthy that he has not expelled any students from Class 1-A yet, despite being well-known for doing so.[15] 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 emphasizes 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 has mentioned on several occasions that some of U.A.'s choices when it comes to examinations are not practical or challenging enough for real hero hopefuls and is adamant about having certain systems used by the institution changed.[16] He also blatantly stated that he did not believe Izuku Midoriya could become a hero when they first met.[7] He is also known for lying to his students in order to manipulate them into giving their best, a technique he describes as a "logical ruse" or "rational deception."[17]

Shota personality Shota's impression on his students. Despite his apathetic traits, Shota genuinely cares about his students and will go to great lengths to protect them. As Eraser Head, he saved Tsuyu Asui from being decayed by Tomura Shigaraki, in spite of his grievous injuries.[18] 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.[19] Recovery Girl even implied that he allowed himself to be captured by Momo Yaoyorozu during her First Term Final Exam in order to boost her confidence.[20] Shota is also quite nurturing, as he has been seen attending to his duties as Eri's guardian and foster father without complaint. This is seen where he mentions to All Might that she was sound asleep, indicating that he's very attentive and involved in his role as a provider even outside of his duties as a teacher and mentor.
