The Danaan is in the shop, and Captain Testarossa is feeling pretty bummed about it. To lighten the mood, Mao drops by Tessa's office, but by the time Tessa arrives, the place is littered with empty beer cans and cigarette butts. Needless to say, Tessa isn't pleased. The situation quickly spirals and Tessa ends up challenging Melissa to an AS duel, with the stipulation the loser has to run around the base naked. Kurz is obviously pleased by the news and clears his schedule to witness that spectacular event. Tessa, being all talk about her "fearsome AS piloting skills”, recruits Sousuke to train her how to operate an AS. Sousuke's definitely going to have his hands full in more ways than one. Training the Captain is proving more folly than fruitful for even an ace pilot like Sousuke, and the odds of her winning don't look good. However, Tessa manages to convince Sousuke of her chances with a daring strategy to beat Mao, which Sousuke readily approves of. Melissa waits impatiently for Tessa to arrive, and fashionably late, she arrives aboard the easier to operate M6 model, rather than the high-tech M9. With biased judges, a daring plan, and Mao's overconfidence working in her favor, Tessa takes to the field and a fearsome duel begins.
