Shoto originally had a cold, aloof personality, which stemmed from his abusive upbringing and complicated family life. Focused and unemotional, Shoto preferred to keep to himself instead of hanging out with other people. After the events of the U.A. Sports Festival, however, Shoto notably became more sociable and kind, even gaining a sense of humor and occasionally smiling, although still retaining some fragments of his previous distant attitude.
