Hajime seems cynical at first glance, but it would be better to describe him as a realist. He is quite skeptical and tends to worry more than the other students, but his worries are usually understandable. He is logical and smart; often annoyed by the idea of not being able to understand someone or something at all. He tends to be quite serious, but he does joke around and often goes along with his classmates' eccentric hobbies anyway, and sometimes smiles awkwardly and sheepishly while his friends engage in some of their usual weird behavior. He is sometimes annoyed by some of his classmates, and can be snarky towards them in his thoughts as well as blunt while speaking to them, though he's more frank than sarcastic or mean-spirited. Though sometimes a bit submissive (especially with bossy girls), he is not afraid to speak his mind, and he can be rude if annoyed enough (for example, after enduring Hiyoko's attitude during her Free Time Events, he finally ends up stating "I don't even care anymore"). He can sometimes be short-tempered and snap at others, especially when he's tired or under pressure. He was also quite paranoid during the start of the game and didn't have much interest in friendship, but he later really wanted to believe in his classmates and felt bad about doubting them during the Class Trials, though he understood it was necessary. He sometimes regretted exposing the murderers, as shown after singling out the murderer in chapter 3.
