It was Taisho Era. Morisaki Shinichiro and his little sister-in-law were managing a cafe that his dead mother had left. His father used to be an excellent scientist, but he began to absorb in studying “android”. People began to cast cold eyes on him, and finally, he disappeared. After that, they two were living poor lives. One day, with a loud noise, an android girl dropped breaking the ceiling of the cafe. Then, their peaceful life suddenly turns into slapstick.
