On Tuesday, Kadokawa said that the one-hour finale of the television anime adaptation of Miki Yoshikawa's A Couple of Cuckoos (Kakk no Iinazuke) manga will air on October 1. On September 17, 24, and 29, the anime will also air special broadcasts that rehash fan favorites.
On April 23, the anime made its debut on TV Asahi and its affiliates during the NUMAnimation programming block. Without a break, the anime will air for two cours (quarters of the year). Outside of Japan, Crunchyroll is broadcasting the animation as well as the English-dubbed version of the program.
Kodansha Comics publishes the manga in English, and it describes the romantic comedy:
16-year-old super-studier Nagi Umino, second-year student at the Megurogawa Academy high school, was switched at birth. On his way to a dinner to meet his birth parents, he accidentally meets the brash, outspoken, Erika Amano, who is determined to make Nagi her fake boyfriend as she never wants to actually marry. But once Nagi makes it to dinner, he finds his parents have decided to resolve the hospital switch by conveniently having him marry the daughter his birth parents raised...who turns out to be none other than Erika herself!
