Sousuke and Kaname 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 somber 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! A day at the beach turns sour after Sousuke misses the point one too many times (and even fails to notice Kaname's new bikini). Then, when Kaname is suddenly kidnapped, it's up to our dense hero to devise a daring rescue!
