Umino Nagi is a straight-A student at a good school who spends most of his time studying and battling his academic rival. He was also accidentally switched at birth. Now that he’s sixteen, he’s going to meet his birth parents. While his sister Sachi, who has been his sister for those sixteen years, decries her brother as an egg-headed loner, her tough act quickly falls when faced with the possibility of losing her brother.
Nagi pats her head and assures Sachi he has no intention of changing his family this late in the game. On his way to the meeting, he encounters a beautiful young woman with twin tails in a frilly dress, seemingly about to jump to her death. Nagi leaps into action, but inadvertently gropes the girl while trying to keep her from jumping. And she wasn’t going to really jump, she was just recording something for her Insta.
While not the most auspicious (or original) manner of meeting, the two soon bond over a common problem: family issues. The girl, one Amano Erika, is trying to start drama in order to convince her mom that she’s not getting married, while Nagi is a mix-up baby. When he learns what school he attends, she decides that he will be her fake boyfriend so she can gt the wedding called off.
When Nagi bristles at this plan and tries to walk away, she holds up very crisp 8K video of him groping her. While I wish there had been one of those *ding-dong* sounds accompanied by a PSA saying “Let’s not blackmail people”, this puts Nagi in a bind, and surrenders. The speed with which Erika resorts to an underhanded tactic is later revealed to be a clue about who she really is and where she comes from.
Despite having the wherewithal to blackmail and mocking Nagi for having never dated anyone, Erika has to google what boyfriends and girlfriends do. Both agree “doin’ it” isn’t a viable option, so she settles for photos of her with her bae. She gets it in her head that if they wear matching badass outfits and he looks tough, her parents will be more inclined to back down. Thus in the middle of this fake boyfriend ploy, they have a dress-up date.
Despite Erika blowing over $3,800 (on her limitless credit card, confirming she’s a rich girl in net worth) none of the photos they take look genuine, but rather look exactly like what they are: staged. Erika ends up going with their first photo, which was taken on accident and thus totally candid and natural, giving you “a sense of the air of the moment,” as she rather poetically put it. Alas, it doesn’t work, and her parents urge her to stop messing around and head home before curfew.
Before she can, Nagi enters another very well-worn but in this case nicely-executed trope of accidental romance anime: revealing surprising toughness when the girl is threatened by three stalkers. This happens very suddenly after an episode that had a nice steady flow, and I feel like another comic disclaimer not to commit assault should have popped up, but I still like how it revealed a new side to Erika: that Nagi’s former delinquent parents brought him up to win any fight he found himself in.
Erika genuinely appreciates his chivalrous behavior, and when her car shows up to take her home, lets him know she’ll delete the blackmail video, something I appreciated being resolved here and now rather than continue to loom over Nagi. Erika reveals that because she’s “like this” she has no friends, but that she and Nagi felt like friends for a day and it was fun. She also says, claiming to be joking later, that if it were him she had to marry, she might not have as much of a problem with it.
Naturally, when Nagi arrives to meet his birth parents, he learns both they and his own parents have arranged for their two kids to marry, so that they can all be one happy family. They just assumed the photo meant they’d already met and were dating!
Tha means his birth parents’ kid, the one he was switched with, is Erika, which explains why she has more of a delinquent streak in her (and sense of street fashion!) than a hoity-toity rich princess. In keeping with the nature she inherited form her birth parents, she follows through on her promise to punch her fiancé the way Nagi punched those punks.
That is one hell of a conceit, and once you suspend your disbelief such a ridiculous arrangement would ever be made between two very different pairs of parents without any input from their children, it looks to be an extremely fun one too. A Couple of Cuckoos arrives fashionably late but looks great and has a goofy but engaging concept, while the 24-episode run means we’ll have ample time to dig into who Nagi and Erika are and how they handle this arrangement.
The two cours also means there’ll be ample time to tell three parallel relationships: between Nagi and Erika, the kids switched at birth, between Nagi and Sachi, siblings not related by blood, and finally the surprise reveal of Nagi’s aforementioned academic rival, who is also his crush, Segawa Hiro (Touyama Nao), whom he’s vowed to confess to once he’s usurped her class ranking throne. Did I mention she can’t remember his name? It’s all a big, beautiful mess!
