Rent Full Metal Panic? FUMOFFU: Vol.1 (2003)

Kaname and Sousuke are back in action! And this time, the battleground is the school ground! High-yield explosives and hilarity come together with a bang as the sombre soldier and his unwitting target brave everything from lovesick "terrorists" to an unforgiving teacher who is bent on revenge. But as good as he is with guns, Sousuke is one clueless commando when it comes to girls - especially Kaname! Don't miss the hilarious antics of everyone's favourite military maniac - and Jih High's most fiery female - as the full-throttle action begins!
