A Couple of Cuckoos' Foster Siblings Threaten to Venture Into Uncomfortable Territory (2024)

The following contains spoilers for A Couple of Cuckoos Episode 11, now streaming on Crunchyroll.

A Couple of Cuckoos is a rom-com anime title that made its debut in the Spring 2022 season and continues well into the Summer season, complete with more than a few twists and turns. But not everything has changed -- some of the show's most uncomfortable plot points remain the same.

This is the tale of the Amano and Umino families, and the accidentally-swapped son and daughter who link them together. While the hardworking Umino Nagi is Erika's fiance, his foster sister Umino Sachi is still being rather possessive of him -- and she doubles down in Episode 11's events. Sachi's idea of familial love is getting a little weird, and it might remind anime fans of the likes of Kiss x Sis or even Oreimo and Eromanga Sensei.

Sachi's Borderline Yandere Love In A Couple Of Cuckoos

A Couple of Cuckoos made it clear early on that Umino Sachi is quite close to her foster brother Nagi, to the point she was deeply saddened to have him leave home and spend time with Erika in the house the Amanos had provided for them. An early episode even depicted Sachi getting inspired by a romance manga scene that showed a foster brother and sister falling in love.

Sachi isn't content to merely daydream about getting together with her beloved Nagi -- she's ready to do something about it and has sometimes chased off any girls who get too close to Nagi -- including the bookish, shrine-loving student Segawa Hiro. In fact, the two might soon become enemies by fighting over Nagi, and it's mainly Sachi who is picking that fight.

Sachi might even be at odds with her biological big sister Erika, whom she generally trusts and admires. The sisters have really bonded by now, but Sachi still can't help but envy Erika's engagement and closeness to Nagi. Sachi can comfort herself knowing that she and Nagi will one day become in-laws, which is a start. But even so, her affection for him seems to be crossing some lines by now, and no one is trying to stop her.

She urgently wants Nagi to see her not as a sister but as a woman, a lady he can find attractive and even fall in love with. Sachi wants to be his little sister while also not being his sister, and it has almost become an obsession by now. It's the only thing she really cares about, and Episode 11 added fuel to the fire when Sachi and Nagi accidentally kissed on the mouth during a power outage -- and Sachi is bitter that Nagi didn't fall in love with her over it.

A Couple of Cuckoos' Foster Siblings Threaten to Venture Into Uncomfortable Territory (2)

Some anime depict brothers and sisters who generally get along like real-life siblings; they may annoy each other but care deeply about one another, such as Shikimori and her cool older brother Fuji or Kaguya-Sama's Shirogane Miyuki and his bratty little sister Kei. In A Couple of Cuckoos, the foster brother/sister bond between Nagi and Sachi was already a little odd to begin with -- and now the other characters are actually promoting Sachi's line-crossing feelings instead of discouraging them. At first, Nagi tried to keep her at arm's length and remind her that they are family who shouldn't love each other in that way. But then Erika donned yet another costume and took things in a different route, and Nagi went along with it.

After a brief lecture from Erika in Episode 11, Nagi went upstairs to Sachi's bedroom door and decided to do things Sachi's way. He agreed to follow Erika's advice and put Sachi's feelings first, declaring he will now see the latter as a proper young woman and not as his kid sister. While Nagi hardly made a love confession to Sachi and didn't give up on Erika or Hiro, he did enable Sachi's strange love, removing one of the few barriers between a Sachi/Nagi pairing.

Sachi goes to bed feeling satisfied and happy about this turn of events, which strongly suggests she will pursue her yandere-style forbidden feelings with renewed vigor when A Couple of Cuckoos continues. Given the current state of all the anime's entangled romances and relationships, Sachi's personal quest might soon become everyone's problem.
