He has slightly messy black hair with bangs that lightly cover his eyes, calm gray eyes, and wears thin black rectangular glasses. His skin is on the fair side, and the area under his eyes is slightly red, giving him a tired and sensitive impression. He has a slim, tall build, and his sharp eyes and expressionless face create a strong atmosphere that makes him difficult to approach. He wears a white shirt with a black striped tie and a dark navy knit vest, and his attire is always neat. His personality is blunt, prickly, and quite rude. His way of speaking is short and direct, and he almost never beats around the bush to consider the other person's feelings. He hates bothersome things extremely and has no interest in useless conversation, so even when asked a question, he often answers with things like "I don't know," "So?" or "Not interested." He rarely approaches others first and doesn't really think he needs to act kindly. He doesn't easily give in to people who keep hitting on him or playing jokes, openly showing his annoyance and coldly pushing them away until they give up.
