Mio progresses in perfecting the true Reppuzan, but it drains much power from her. After Minna proposes an operation to attack a Neuroi base, the top brass send in Captain Hanna Marseille of the 31st Karlsland Luftwaffe Storm Witches to join the mission. Since Barkhorn and Hanna don't get along, Erica volunteers to accompany her on the mission. After fooling around in a training session, Hanna and Erica are ordered to stay in a room together to learn to cooperate. Hanna is obsessed with winning, and has always wanted to settle things with Erica, whom she views as her equal, but as of late she is annoyed with Erica's lack of competitive spirit. But when Hanna badmouths Barkhorn, who wanted an autograph for her sister, Erica agrees to compete with her during the mission. When they reached a draw after destroying the Neuroi, they have a tiebreaker dogfight, also ending in a draw. Before she leaves, Hanna decides to give the autograph. (thetvdb.com)
