Kazuo is a young man. He may appear as cold and reserved, but actually he's not mean. On the contrary, he's a quite respectful young man, especially towards women, as he was taught. He owns a female shiba-inu named Pazu, and often goes for a walk with his pet. He's getting sick easily, especially at winter season. He's not very good at showing much emotion. So he's not very emotional without a reason.
