Full Metal Panic! (novel) Volume 2: One Night Stand

The story of gung-ho young secret agent Sosuke Sagara, assigned to go undercover and protect high-school honor-student Kaname Chidori from a band of international terrorists. Needless to say, Sosuke's background as a counter insurgent guerilla isn't the best possible preparation for high school! In this volume, a member of the terrorist group A21 has a psychotic episode and is taken into custody. When Tessa and Kalinin are called in to question him, they fall under attack by other A21 members.
