Shiro has a foolhardy personality, despite being a very skilled fighter. When he sees a challenge, he rushes in without giving a second thought. As a result, he often puts himself in danger. However, he is extremely friendly, sociable and easy to get along with, as seen in his many supports, and is open minded and accepting of people with unique traits such as Nina. He is also extremely fond of chicken, as seen in his supports with Selkie and Rhajat.
