Based on the manga series by Hiromitsu Takeda, this romantic comedy is about Takeru Ohyama, a typical perverted teenage boy. His new school doesn't require entrance exams, and it just turned co-ed! Unfortunately, his dreams of a happy high school life are dashed when he finds out the school is much more than it seems. All of the students wield a special item—a Maken—to unleash their magical abilities in duels! Can Takeru find a Maken that works for him? Even while trying to fit in at a new school and dealing with all kinds of girl problems? (Source: FUNimation)

Takeru continues his education at Tenbi Academy as part of the newly formed Security Committee. As a team with the other members, they battle unscrupulous individuals who use their Maken for evil purposes. In the meantime, his libido and the conflicting romantic interests of the girls surrounding him complicate matters considerably. (Source: ANN)

OVA episodes bundled with the 8th and 11th volumes of the manga.

In the world of Prester, flight is the dominant mode of transportation, made possible by Claudia Fluid: a liquidized form of the crystals that are produced on the planet. An organization known solely as "the Guild" has absolute authority over the skies, with a monopoly on the engines that make use of this fluid. Moreover, as ecological disasters destabilize the warring countries of Anatoray and Disith, the Guild also arbitrates in the disputes between the two. Caught in the middle of the conflict are Sky Couriers, piloting small, two-person vanships that fly freely through the sky. Last Exile follows the adventures of two teenagers who dream of surpassing their parents: Claus Valca, son of a famous vanship pilot, and Lavie Head, Claus' best friend and navigator. Their job as couriers entails passing through an air current called the Grand Stream that separates the hostile nations, which even standard airships struggle to survive. However, when they take on a high-rated delivery to bring an orphan girl named Alvis Hamilton to the battleship Silvana, they get dragged into a much greater conflict that pits them against the might of the Guild.
