Shota is a very stern and reserved man who has lofty expectations of his others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations. Shota has proven to be very vocal and unafraid when expressing his ideas. Despite his apathetic traits, Shota genuinely cares about his students and family and will go to great lengths to protect them. Even with his stern demeanor, Shota has a softer side that shows itself on occasion. Shota is also quite nurturing, he has demonstrated to be very attentive and involved in his role as a provider even outside of his duties as a teacher and mentor. 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.

Hizashi maintains the eccentric persona of a radio host. He often poses when he talks and maintains a certain level of excitement or volume, regardless of the situation. He has an innate desire to entertain, and will exaggerate happenings to hype up a crowd. Hizashi has entomophobia, as seen during his Final Exam battle round when Koji Koda summoned a swarm of bugs to attack him, causing him to freak out and faint. Because of this, he admits to preferring urban areas over forested ones. As opposed to Shota, who is more sensitive and emotional when it comes to the grief of Oboro's death, Hizashi has surprisingly proven himself to be the more solemn and down to earth of the pair. He initially refused to believe that Oboro was Kurogiri, and following their meeting with him in Tartarus, Hizashi fell into a silent rage, saying that he would kill whoever was responsible. Showing he cares very deeply for all of his friends and family.
