The upcoming comedy romance anime A Couple of Cuckoos, Season 2 got a new trailer, a brand new character, a cute key visual and an official premiere date earlier today via the anime’s official X account.
That premiere date is now set as July, 2025, with new character introduced as online singer Ai Mochizuki (see above and below).
Ai is voiced by Hina Youmiya (Yuki in Shoshimin: How to Become Ordinary), and she isn’t just the girl who has recently moved back to Japan from China.
She is also protagonist Nagi’s childhood friend, and someone who has been desperately in love with him since she was little.

It ends with the first appearance of Ai, who is thrilled she is finally back in Japan as it’s “10 years” since she last saw Nagi.
Yep, things are apparently about to get interesting.

A Couple of Cuckoos, Season 2 details
Like its first season, A Couple of Cuckoos, Season 2 is also based on the hit manga series written and illustrated by Miki Yoshikawa.
This time, however, Season 2 is being directed by Masakazu Hishida (My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against Me!), who is taking over from Season 1 director Yoshiyuki Shirahata.
Yuzuru Aoba is new to the staff and responsible for series composition, with Kyouko Kon (Classroom of the Elite) taking over the designing of the characters.
Studio Okuruto Noboru is also taking over animation from Season 1’s SynergySP, and Shin-Ei Animation, with a studio change always a concern, as we have seen so many disastrous results in popular anime in the past, eh?
We will just have to see how it goes.
As for the plot of Season 2 of A Couple of Cuckoos it goes like this:
Nagi Umino and Erika Amano.
Born on the same day, these two were accidentally switched at birth.Raised as the son of a diner owner and the daughter of a hotel tycoon, the two are pushed into an arranged engagement by both their birth and adoptive parents.
As they begin living together under one roof, their lives soon intertwine with classmates like Hiro Segawa and Natsumi’s younger sister, Sachi Umino.
Fiancée, crush, stepsister—a messy “love square” forms around Nagi, and now, his childhood first love arrives!?
Life and love collide in chaos! A “pentagon romance” comedy that starts with a baby mix-up!
This summer, fate takes an even bigger turn!
Now that’s one messed up dating situation, eh?
