Hitoshi Tadano is an assistant manager at an advertising company who appears to be nothing more than a dull and incapable "nobody." While most employees wonder why such a passive and incompetent person like Hitoshi hasn't been laid off yet, there is one person who heavily relies on him as a "savior" for the company: the CEO. In reality, the "Mr. Nobody" persona is just a disguise for the real Hitoshi, as he is engaged in various special missions from the CEO to quietly carry out his "extraordinary" task of combating the company's corruption.
