Full Metal Panic! Invisible Victory

Sinopsis

Nine months have passed since teen soldier Sousuke Sagara first became Kaname Chidori's covert protector. In that time, Mithril has been remarkably successful at thwarting Amalgam's efforts, but this has only made Amalgam more determined. Leonard Testarossa's visits with Tessa and Kaname are just preludes to all-out attacks that begin with global communications disruptions. Kaname's status as a Whispered makes her one of Amalgam's main targets, which means that any semblance of a peaceful life at Jindai Municipal High School is now over for her.
