Hitoshi Tadano, the Extraordinary Undercover Detective (Season 3)

Hitoshi Tadano is an assistant manager of an advertisement company who seems to be nothing but a dull and incapable “nobody”. While most of the employees wonder why such a passive and incompetent person like Hitoshi is yet to be laid off, there is just one person who heavily relies on him as a “savior” to the company, the CEO. In fact, the “Mr. Nobody” is simply a disguise from the real Hitoshi, as he is under various special missions of the CEO to quietly carry on his “extraordinary” task to fight against the corruption of the company.
