In recent times, households are increasingly adopting robotic OrderMaids as helpers. Among these, 10-year-old Bondo Taira has discovered that two of his closest companions-Motsuo and Gachi Gorilla-have their own OrderMaids. Motsuo's robot maid, Meico, is particularly noteworthy for her ability to provide excellent massages and serve drinks with a friendly demeanor. Inspired by this experience, Bondo convinces his mother to purchase an OrderMaid of his own.
However, when the chosen robot arrives at Bondo's home, it turns out to be quite different from what he had envisioned. Named Roboko, this powerful and clumsy machine is capable of causing significant damage to a house while performing even simple tasks. Despite this initial disappointment, Bondo decides to give Roboko a chance and learn more about her capabilities.
As it turns out, Roboko possesses far greater potential than what was initially assumed. With the help of his friends Motsuo and Gachi Gorilla, Bondo discovers that there is much more to Roboko than he could have ever imagined.
