Akitsu Masanosuke (voiced by Namikawa Daisuke) suffers a lot in life because of his shy and cowardly character, and he has lost countless jobs because of it. One day, Masanosuke, who had just been fired, met a mysterious man. The man called himself Yaichi (voiced by Sakurai Takahiro) and wanted to hire Masanos as a personal bodyguard. Masanosuke, who had nothing to do, agreed immediately. Unexpectedly, this chance encounter involved Masanos in a kidnapping case, and Yaichi was the leader of the famous criminal gang "Five Leaves". What kind of experience will await the innocent Masanos? Forced to make a living, Masanosuke became a member of Five Leaves.
