Nagi Umino is the main male protagonist of A Couple of Cuckoos Series. He is a second-year student at Megurogawa Gakuen. He is the biological son of a hotel tycoon, but due to a mix-up after his birth is raised by a different family.
Nagi seems to be obsessed with studying to the point that he studies day and night in order to achieve top marks. He is quite capable in pretty much everything, whether it is housework or schoolwork, proving his culinary skills multiple times by preparing delicious dishes everyday. He is a free-willed and determined person with a stubborn attitude to never give up. He is also naïve when it comes to the girls around him. Yet his kindhearted nature means that he will protect the ones that he cares about by doing everything in his power to help them.

Mixed up with another family's child as a baby, high school student Umino Nagi is finally meeting his biological parents. On the day of their meeting, he happens to encounter Amano Erika, a high school student at a prestigious and wealthy girls school. At her request, he's half-forced into pretending to be her boyfriend so she can avoid marrying her fiance....However, not only were they the babies who had been mixed up, they're also engaged to each other! The loving parents of both families officially recognize their engagement, and the couple begins living together. Nagi is in love with his classmate Segawa Hiro, and Erika is determined to rebel against her father, so the couple agree not to get involved with each other. The mixed-up and chaotic romantic comedy starts now!
