O.K. Sumanosuke

One day, Makina brought home a human robot a.k.a Baromettsu that she had picked up from a rubbish dump. Later, due to a malfunction, the robot registered her as his master!? Makina dislikes robots and wanted to make him leave but... since he's kinda handsome, she decided to let him stay for a while and even named him Sumanosuke. However! Despite Sumanosuke's high specs, he is surprisingly clumsy and everyday has been a series of unexpected incidences!
