Mithra Casper is a student of Makoto Misumi at the Rotsgard Academy. In his daily life, he has a passive personality and tends to go along with the flow of those around him. However, when it comes to battle, he transforms into a dependable and responsible fighter who serves as the shield of his party. His parents are ardent followers of the goddess, which influences his background. As a supporting character, Mithra’s primary role is to be one of Makoto’s pupils, and his combat abilities focus on defensive techniques that protect his teammates. While his passive nature outside of combat can make him easily swayed by others, his reliability in dangerous situations earns him the trust of his companions. His personal motivations are not deeply explored, but his actions indicate a strong sense of duty toward his group. Over the course of the story, Mithra shows gradual growth in confidence as he learns under Makoto’s guidance, though his development remains limited compared to more central characters.
