Although he grew up watching Gekiganger 3, a mecha anime, Akito has no interest in fighting and would rather cook. However, when his home on Mars is destroyed and he is mysteriously transported to Earth, he seeks answers and follows Yurika, the captain of the battleship Nadesico. He joins the crew as their cook and handy back-up mecha pilot, thanks to his nanite implants. The crew may seem like a group of misfits, otakus, and ditzes, but they are actually handpicked experts dedicated to avenging Mars. Together, they journey back to Mars and confront the harsh realities of life beyond the world of mecha anime.
