Muirne is kind, selfless, sometimes stubborn, and more than willing to provide assistance to those who need her help. She also has an adamant determination to fight against the Grannvale Empire, due to her strong moral compass rejecting their evil practices. However, Muirne suffers from a low self-esteem due to the fact that she is a mere commoner lacking Holy Blood. This causes her to feel inferior to practically everyone else in the army, particularly Seliph, whom she harbors feelings for.
