 __Background Information:__    Teletha &quot;Tessa&quot; Testarossa is the clumsy but charming Captain of the revered TDD-1 &#039;Tuatha de Danaan&#039; submarine of the anti-terrorist organization &#039;Mithril&#039;. She is American by birth but has lived on submarines and military bases for the majority of her life time. She is a child prodigy who rose to such a high rank at the age of only 16, has silver hair and grey eyes.      ~!Later revealed as being a Whispered, her high level of mathematical and scientific adeptness is dwarfed only by her brother&#039;s, which seems to have given her a sense of inferiority.!~     She is also  not very athletically inclined, but has shown to be a very good swimmer. She has an interest in Sousuke that extends beyond a professional one, generating a love triangle she shares with Sousuke Sagara and Kaname Chidori. Even though Chidori and Tessa seem to compete against each other for Sousuke, they are good friends in reality, as during several episodes they talk about Sousuke and his unique military charm. Tessa is also one of the chief designers of the TDD-1 &#039;Tuatha de Danaan&#039;, and the creator of Dana, the submarine&#039;s Artificial Intelligence.       __Characteristics:__    Tessa has a lot of interesting qualities. Her subordinates are what she cares with the most. She is also very smart when it comes to battlefield tactics and conflicts and she displays some very impressive military prowess and strategy at several points. She also seems to have a nervous habit of playing with her ponytail.    Sometimes however, as stated by Kurz Weber, &quot;whenever Tessa was told by someone she couldn&#039;t do something, she made it a point to prove them wrong&quot;. Tessa seems to have some trouble tolerating her job at times due to the position she has. Some scenes have shown her irritated by what she does while other scenes show her slightly depressed by it. Nevertheless, she seems to have a large amount of stamina, and is able to cope with the stress of her tasks, and does a wonderful job doing so.    (Source: Wikipedia)

Sousuke Sagara, a seventeen year old military specialist working for the secret organization MITHRIL, has been assigned to protect the latest "Whispered" candidate Kaname Chidori.

Unfortunately for Sousuke, the toughest part of his mission isn't only protecting Miss Chidori but also getting used to living an average High School students life, no easy task for someone raised on the battlefield.

It's back-to-school mayhem with Kaname Chidori and her war-freak classmate Sousuke Sagara as they encounter more misadventures in and out of Jindai High School. But when Kaname gets into some serious trouble, Sousuke takes the guise of Bonta-kun - the gun-wielding, butt-kicking mascot. And while he struggles to continue living as a normal teenager, Sousuke also has to deal with protecting his superior officer Teletha Testarossa, who has decided to take a vacation from Mithril and spend a couple of weeks as his and Kaname's classmate.

Tells the same story as Full Metal Panic Second Raid and is as such, also based on the novels The End Of Day By Day. 
Leaving off after the original series, this series tells of Sousuke and Mithril as they fight Amalgam. Like the original series, but both sides have gotten a bit more aggressive...

Much akin to Full Metal Panic? Fumoffu, Overload is a series of seemingly random, silly, high school adventures of Sousuke and Chidori.

Jindai High School was a relatively safe place, right up until Sousuke Sagaka transferred there. A total nut, he wreaks havoc on the school's student body and gets into a world of trouble with the teachers! But there's more to Sousuke than meets the eye&mdash;not just a hell-raising student, he's actually a member of an elite military unit, on an undercover mission to protect the beautiful schoolgirl Kaname Chidori from the KGB.

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.
