Ginta's father works at a cellphone company called "Choto Bank." Their new cellphone is a humanoid cellphone. Gina's father sent his son a prototype version of the humanoid cellphone, but Ginta's sister unexpectedly made some "changes" to the new cellphone and due to that it makes countless mistakes. The cellphone humanoid, named Momoko, slips on flat surfaces, rips Ginta's jacket, turns a jacket into a puzzle, and trips and nearly kills Ginta when a pair of scissors slip out of her hand. Ginta asks himself, "Will I live long in this condition?"
