Highlights of A Couple of Cuckoos anime

Storyline of the anime


Nagi Umino, a second-year high school student who is 17 years old, discovers that his parents did not give him up for adoption.

Erika Amano, a well-known internet personality who is attempting to flee an arranged marriage, is someone he meets on the way to his initial meeting with his biological family.

Later, Nagi and Erika learn that their parents had mistakenly given birth to the wrong pair and were now attempting to organise a marriage for them.

They are forced to live in a home owned by Erika’s family in order to make this possible.

A big error that occurred many years ago when a small boy and girl were born in a hospital would forever alter the lives of the two kids. Nagi is currently studying English vocabulary while simultaneously frying two eggs for breakfast at the Umino Family Diner.



He is shortly joined by his sister Sachi, who has just woken up and insists on having the egg he is preparing with the larger yolk. Nagi, however, declines because the yolk has vitamins that help with memory.

When their mother Namie arrives and asks where she left her earrings, Sachi exits the frame and quarrels with their father Yohei off-screen. Nagi then tells Namie where the earrings were.

Namie praises him and looks forward to meeting his true parents and their real daughter after learning that knowledge. His parents warn Nagi to be on time since they’ll be waiting for him in the dining hall as he sits in his room and considers being switched at birth.

Nagi blushes as Namie also bids him a happy birthday. Nagi refuses to move in with his birth parents when Sachi asks him to do so and instead says that he would go to the library and study in the interim.

When asked why he wants to defeat his opponent, Sachi responds by mentioning some of Nagi’s eccentricities. While Sachi sobs and says she doesn’t want him to leave, Nagi smiles and blows off the remarks.

He has a strong sense of independence, is tenacious, and refuses to give up. In terms of the girls in his immediate vicinity, he is equally naive. But because of his compassionate nature, he will protect the people he loves by doing everything in his ability to assist them.

Nagi is incredibly smart and diligent in his study habits.
Nagi is a person of great strength. Erika and Nagi initially came into contact when Erika prepared to jump off a bridge.


Nagi instantly went to save her when he witnessed this, only to learn that she was making the whole thing up to get attention from her parents and her Instagram followers.

After the misunderstanding was resolved, Erika informed Nagi that her parents intended to arrange her marriage. As a result, Erika asked Nagi to play the role of her phoney lover so that she could leave the situation. Nagi refused, but Erika coerced him into complying.

He ended up beating up some of Erika’s stalkers and they parted ways after spending some time together and going shopping. They had no idea that their parents were the same and that Erika’s fiancé was none other than him.

Erika first met Nagi when Nagi intervened to stop Erika from making a provocative film. They resolved to get along with their families after learning that they were the babies who were switched at birth and that both of their parents had consented to arrange their marriage.
