Kuwagata Koichi (Sato Ryuta) is an associate professor at the department of literature of a third-rate university. Society for some reason refers to him as a “great sleuth”, but he does not have the disposition of someone famous. On the surface, he appears cool and collected. But inside, he is extremely intense – his heart would soar if he were praised and he would slump deep into the ground if he were stomped on. He has led the life of a loser because his idiosyncracies attract a succession of cases and small disasters. However, he decides to make a fresh start in life, bidding farewell to his wretched past and entering a stylish life of breezily overcoming crises with his post at the university. He attempts to solve every difficult problem by using his ever-changing wild ideas. His partner is Shinno Hitomi (Sakuraba Nanami), a second-year literature student at the university and the only who knows of the bad ideas that unfold in Kuwagata’s mind.
