Chihiro is very intelligent, but he also has a very meek and timid personality. He is very shy and apologizes a lot, it's easy to intimidate him to the point of tears, he also loves to talk about anything related to his work as a programmer and he becomes more lively whenever the topic is brought up. Chihiro is one of the kindest and softest people, as he literally wouldn't hurt a mosquito because it's hungry and might have a family. He was bullied due to his 'not acting tough as a boy'.
