At first, Shoto exhibited a cold and aloof attitude, often preferring to keep to himself rather than socializing with his peers and commonly focusing on the task at hand. Despite seeming cold, however, Shoto isn't openly cruel, mean or rude, and his distant behaviour is likely a result of his complicated home life, as well as growing apart from his siblings. Shoto detested the fire half of his Quirk, given that his fire abilities were inherited from his abusive father Endeavor.
