On the surface, Kaname Chidori appears to be a normal, popular high school student. The problem is, she doesn't realize just how popular she is. Unbeknownst to her, a group of terrorists believe she possesses the special powers of 'the Whispered', and they're out to kidnap her. Enter Sousuke Sagara, a young, hotshot agent from the stealthy anti-terrorist organization Mithril. Will he be able to protect Kaname without her finding out what's really going on? Or will he just drive her crazy as he tries to fit in as her awkward, gung-ho, war-crazed classmate?
