Canon, AU, or OC?: Canon
Universe of Origin: Diebuster
Personality: A simple girl, sometimes clumsy, with near endless optimism and a bubble personality that can get on people's nerves. Will hold on to her ideals no matter the cost, and determined to fulfill her dream of becoming a space pilot. Idealizes 'Nonoriri"
Abilities/Weapons: She's actually a robot, thus having endurance and strength beyond that of a human, and doesn't need protection to go in space. Has the ability to Warp instantaneously, can absorb energy blasts with lenses on the back of her hands and chest, has thrusters, eight banks of lasers on her legs. Can also use a Buster beam, with which she can slice a moon in half via drop kick, or create micro-singularities (aka black holes). Can control other Buster machines
Backstory: Built some time in the far past after Gunbuster, Nono was damaged and recovered in space, her memory lost. Growing up as a farm girl, she dreamed of eventually becoming a space pilot, and she traveled to the city to make her dream come true. She got a job as a waitress, though not a very good one, where she met Topless pilot Lal'c, who she immediately attached to. Joining the elite Fraternity, she goes through several misadventures fighting giant space monsters before an actual space monster wakes up, revealing that all the ones fought before were machines made by humanity to protect itself. At that point her memories returned, bringing back her identity as Buster Machine #7. That space monster is killed, only for another to approach. All fighting is useless it seems, until Nono returns, having welded the entire Solar Defense Force into a giant Buster Machine the size of Earth. That Buster Machine fails, and Nono emerges to fight with Lal'C and defeat the true space monster. However, Nono is forced to depart to save Earth from the black holes created and vanishes
