Akito doesn't want to fight. Despite a childhood spent on the anime Gekiganger 3, a Mecha show, he'd rather cook than pilot a Mecha. Fate intervenes when his home on Mars is destroyed, and he is transported instantly to the Earth, mysteriously. He has questions no one can answer fully, but follows a girl from a chance meeting in hopes to discover any. The girl, Yurika, is captain of the private battleship Nadesico, and in order to follow her, he enlists as their cook. Possessing the nanite implants that allow to control mechas, he's a handy backup pilot for the mechas of the Nadesico. He joins a crew bent on avenging Mars that seems to be composed of only misfits, otakus, and ditzes; however, in reality, they are handpicked experts. They take their own private war back to Mars to face the harsh reality that life may not always be like a Giant Mecha series. (Source: ANN)

Chise is an ordinary schoolgirl: small, frail, and not particularly intelligent. Her greatest joy is her budding romance with her classmate and childhood friend, Shuuji. They both live in a small military town in Hokkaido, where high schoolers have few concerns other than who is dating whom and complaining about the steep climb up "Hell Hill" every day before school. One day, Shuuji and his friends make a trip to Sapporo to buy gifts for their girlfriends. A massive air raid on Sapporo that day kills thousands, including one of Shuuji's friends, and signals the beginning of a war. Fleeing from the carnage, Shuuji spots Chise, though now she has steel wings and a massive gun where her right arm should be. Against her will, she has been transformed into the ultimate cyborg weapon, capable of leveling entire cities. As the war rages closer and closer to their hometown, Chise and Shuuji's relationship is strained by her transformation, and they are left to wonder whether she is even still human.
