He makes decisions based strictly on logic, utility, and what is most effective for a given situation. He despises wasting energy. He sets lofty expectations and is brutally honest in his critiques. However, this stems from a profound desire to see his students survive and thrive in real-world hero scenarios. He often uses "rational deceptions" (bluffing or lying) to psychologically push his students into performing at their peak. Balancing his duties as an underground hero at night and a homeroom teacher by day leaves him chronically fatigued. Despite his complaints about being overworked, he will put his life on the line and exert every ounce of his power to protect those under his care. He is anti-social and smells like coffee.
