Sousuke Sagara is far from the average high school student - not only is he highly trained in military tactics, he puts his knowledge to use in every single applicable situation (and even those nonapplicable ones.) So, when confronted with high school, he tends to turn average high school experiences into off-the-wall adventures. Love letters become terrorist threats and field trips become commando operations; his survival depends on the watchful eye of his best friend and classmate, Kaname. Together, they may just make it out of high school alive...

These two series are what I like to refer to as a "soldier theme" series. Meaning, that they deal with soldiers, and all the classic themes and stories. The stories usually are, fighting far away yet have a love back home to think of, soldiers who wish to die, friend vs friend, heroic tales against the odds, death of comrades to name a few.
In the year 2010, an environmental disaster has decimated the human population, leaving the remnants struggling to survive. Out of these rose an oppressive and wealthy ruling class, the Logos, who live comfortably in their special economic zones while the majority of humanity struggle and suffer in the ruins of the past. Two men, Katsuragi Jo and Tsurasawa Hitoshi, desert their military unit 'Phantom', taking with them a mysterious little girl. Why did they side with the resistance they once helped suppress, and what’s the significance of this innocent young girl?
Both Full Metal Panic! and Innocent Venus center around the protection of one girl and feature mecha units that they use to fight. Both of the girls develop a "love" for their protectors. Although in Full Metal Panic it's a romantic type love, while in Innocent Venus it's more of a father-daughter type love. Innocent Venus is a little more serious than FMP!, but there are a few characters in Innocent Venus that provide some comic relief. If you liked one, then you should give the other a try.
Keitaro Urashima is somewhat of a failure. In order to fulfill a promise he made to a girl fifteen years ago, he has tried time and again to get into Tokyo U but has never managed to pass the exam. However, fate smiles upon him and he ends up working for his aunt, managing an all-girls dorm! Living with the feral Kaolla, the timid Shinobu, the sake-loving Mitsune, the blade mistress Motoko and the punch-happy Naru, can Keitaro keep his focus and keep his promise? And will he ever end up meeting that girl from his past?
In the world of Prestal, Noble men perform noble deeds for noble purposes. All of this is performed under the careful gaze of the Guild, a race apart who live in cities in the sky. We see this world through the eyes of Claus Valca and Lavi Head, as their travels take us above, beyond and through Prestal, and their actions cause ripples that shall never fade.
Last Exile and Full Metal Panic have a similar feel to them in regards to the combination of action scenes and character drama. Full Metal Panic involves fighting in robotic machines, while Last Exile is centered around warfare in the skies, but both have well developed characters and interactions, not to mention friendship and relationship drama. If you like either series for its plot tension, it's safe to say you'd like the other.
