Setsuna is one of the most calm Soldiers. As a soldier, she is usually the one who keeps the coolest head. She seems detached from much of the action but is actually quite involved, often reserving her appearances for the times when she is needed the most. She rarely voices her opinions about things, having a very reserved personality. She seems intensely focused on her work as a Soldier, which is a valuable skill for one who must guard the gates of time! She takes her job very seriously. She is passionate about whatever she does and never takes half measures.
