It's romance and intrigue in the fourth volume of the smash hit Full Metal Panic!

First, Kaname runs into her former upperclassman, a real dreamboat who looks like he's finally going to ask her out. But are his intentions honorable? Sosuke goes undercover as a costumed figure named Bonta-kun to find out. But when a band of local thugs starts picking on her, it's a rifle-wielding Bonta-kun to the rescue!

Later, it looks like Kaname is at last ready to open up to her feelings about Sosuke. She takes a home-made lunch over to his apartment... but wait! Isn't that Tessa walking out of Sosuke's shower?!

Next thing you know, terrorists are shooting up Sosuke's apartment, and Kaname and Tessa are being held at knifepoint!
