Reception.
During the Anime News Network's summer 2010 anime previews, Gia Manry commented that the first anime series would be a hard sell because of its focus on Japanese history, but that the comedy is largely based on famous historical figures saying silly things. Commenting on the second season, ANN reviewer Bamboo Dong states that it "break[s] up the monotony of the work day" and was good for a quick laugh. She also states that the writers of the second series have what it takes to translate the manga into a visual medium. In "Otaku USA"s preview of series being simulcast by Crunchyroll beginning in March 2011, it described "Tono to Issho" as a champion of the comedy genre.
