Compared to the other residents of the Polar Star Dormitory, Shun is less energetic. He does not speak much, but if he does, he speaks quite bluntly and flatly. While most of his fellow residents and classmates may get worked up when something bad happens, Shun remains calm and collected so he does not make mistakes. Despite not appearing so, Shun does want to be the best in the academy and is prone to sulk whenever he loses. Shun is often annoyed by the impulsiveness of his fellow dormmates but does care for their well-being. Overall, Shun is a realist, accepting things as they are.
