Shirotsugh "Shiro" Lhadatt may be a cadet in the Kingdom of Honneamise's Royal Space Force (RSF), but he has never been in space before—in fact, nobody has. The RSF is often regarded as a failure both by the country's citizens and a government more interested in precipitating a war with a neighboring country than scientific achievement. Following the funeral of a fellow cadet, an unmotivated Shiro is walking in the city one night, when he bumps into Riquinni Nonderaiko, a young, pious woman, genuinely enthusiastic about the significance of space exploration. As the two gradually bond, Riquinni's encouragement inspires Shiro to volunteer as a pilot for a prospective rocket ship, potentially becoming Honneamise's first man in space. Shiro and the RSF are soon joined by a team of elderly but eager scientists and engineers, and together, they embark on a mission to mold their nation's space program into a success. However, their efforts soon catch the attention of the government, which seems to have a different plan for the RSF in mind. Even as the odds are stacked against them, these men and women continue to stubbornly look to the sky, because somewhere among the frontiers of space may lie humanity's last chance at redemption.

Traumatized by school, Jun Sakurada spends his days at home as a shut-in, purchasing things online, only to send them back before the free trial period ends. So when a note appears on his desk, asking whether or not he would wind something, he assumes it was something he ordered and carelessly circles "yes," changing his life forever. A box arrives with a wind up doll inside, but this is no ordinary toy: after Jun winds her up, she begins walking and talking as if a normal person. With a haughty attitude, she introduces herself as Shinku, the fifth doll in the Rozen Maiden collection, a group of special dolls made by the legendary dollmaker Rozen. These sisters must battle each other in a competition called the Alice Game with the help of a human to ensure victory. The winner becomes Alice, a real girl who is worthy of meeting their creator. As more sentient dolls end up taking residence in Jun's house, and a foe from Shinku's past makes her appearance, Jun's life becomes far more complicated than he ever thought possible.
