Simoun

is a Japanese anime series created by Shō Aikawa, Yoshizaki Sasa and Gō Mihara. It ran for 26 episodes on TV Tokyo from April 3 to September 25, 2006.

A manga adaptation was published in three issues of Comic Yuri Hime. The manga shared the same characters and setting as the anime, but presented a different storyline. A second manga was serialised in Megami Magazine, with a radically different setting and a comic rather than serious and dramatic tone. There is also a two-volume light novel adaptation, with its storyline close to that of the anime.

In May 2007, Simoun was licensed for release in North America by Media Blasters.

Plot
In the peaceful theocracy of Simulicram, everyone is born female until when they reach the age of 17, where each maiden undergoes a special ceremony where she chooses her gender. However, only Pairs of maiden priestesses can synchronize with the ancient flying ships known as Simoun needed to defend Simulicram. These Pairs refrain from undergoing the ceremony as long as they wish to keep piloting their Simoun.

Aer is recruited to be a Simoun pilot after a terrifying attack by an enemy nation decimates the squadron known as Chor Tempest. To earn her wings she needs to find her way into the heart of Neviril, Regina of Chor Tempest. But Neviril's heart still belongs to her previous Pair, lost in the battle when she attempted a forbidden Simoun maneuver.
