Setsuna believes that war can only be stopped through direct confrontation, and therefore has little tolerance for diplomats and politicians, believing that their "peace talks" only lengthen the conflict and cause more casualties.

Setsuna decidedly spends most of his time with Lockon Stratos, compared to the other Meisters, who, in turn, looks out for him.
