Mireille Grangeon Ritsu is skeptical of letting Mirelle stay because of her infamous history, but Ars agrees to allow her to stay. Mirelle is disliked by most of the subordinates (except for Charlotte) due to her incompetence, so they decide to settle things in a mock battle. Most of the soldiers join Ritsu, while Ars is partnered with Mirelle. During the fight, a mage working for Mirelle informs Ritsu of her plan, but the soldiers discover his ruse. Mirelle reveals her intelligence by tricking Ritsu’s team into attacking decoy targets before leading them to chase her carrying Ars.
