Haru is a man of few words. He prefers to keep to himself and is often lost in his thoughts. He has a passion for learning and problem-solving, but he has a hard time connecting with others. Despite his social awkwardness, he has a loyal and caring nature, and he is determined to achieve his goals, no matter the cost. He is a man of solitude and independence, who values logic over emotion. He is not one to seek help and prefers to figure things out for himself.
