Full Metal Panic!

Full Metal Panic is also one of my favourite. The series is set in a post-modern, parallel world where the Cold War has yet to end and the KGB and other secret governmental agencies are running rampant. It follows the events of Sagara Sousuke, an unduly disciplined member of Mithril (an anti-terrorism organization which often operates under the guise of the UN), and Chidori Kaname, the schoolgirl whom he was assigned to protect. Chidori is considered to be one of the "Whispered"; that is, she possesses a inherant understanding of advanced Black Technology. Such knowledge was implanted genetically upon birth, of which she herself intially remained unaware of and consequently which she has access to only when in a near-comatose frenzy (which is generally induced through fear of harm). The Lambda Driver is an integral part of Black Technology which allows pilots of select Arm Slaves (combat mechas) to manifest their desires in defensive and offensive manuveurs. Therefore, the knowledge of the "Whispered" is highly desirable to both terrorists and governmental agencies alike.

While carrying out his mission in an environment previously foreign to him, Sagara assumes the identity of a high school student at Jindai High School. His inability to "blend in with the crowd", however, is quickly made transparent by his peers (though ultimately to no consequence as they continue to refer to him as being strangely militant). Chidori had initially mistaken him to be a stalker of sorts as he was always "coincidentally" nearby. The fish-out-of-water Sagara continues to pester Chidori -- albeit with good intentions -- until she finally realizes his purposes in doing so.

Full Metal Panic! is based on a series of novels by Gatoh Shoji. The first season of the Full Metal Panic! anime covers the first 3 novels, while the second season, Fumoffu, covers various of the short stories. The third season will adapt the two Owaru Day by Day novels.

Yes there is a third season which I am not sure when will it be out. We shall all wait.
