Hajime seems cynical at first glance, but it would be more accurate 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 keen, 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.
