After being reincarnated into her favorite action otome game, Angela discovers that she has become the saintess, one of the two playable protagonists. Unfortunately, her new body is suited for healing and support magic rather than physical combat. Determined to become a powerful frontline fighter, Angela decides to use enhancement magic on herself. Through intensive magical training and muscle-building, she eventually develops extraordinary combat abilities. When monsters begin threatening the kingdom, Angela joins a special team led by a prince to investigate and eliminate the growing danger. With her overwhelming strength, unconventional fighting style, and giant weapon, she becomes a battle-loving saintess who cares far more about fighting than romance.
