A Cat and a Kitten's Rock & Roll
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.

Full Metal Panic!
Sousuke Sagara, a seventeen year old military specialist working for the secret organization MITHRIL, has been assigned to protect the latest "Whispered" candidate Kaname Chidori. To complete this task Sousuke will have to deal with enemies from his past as well as the occasional panty thief. Unfortunately for Sousuke, the toughest part of his mission isn't only protecting Miss Chidori but also getting used to living an average High School students life, no easy task for someone raised on the battlefield.
