What the Final Arc Announcement Means
When a long-running shōnen romantic comedy like A Couple of Cuckoos moves into its final arc, readers can expect tighter plotting, escalated character development, and the settling of major romantic threads. For a series built around identity, family secrets, and the awkward friction of teenage romance, the final arc typically aims to clarify relationships, reveal lingering mysteries, and move protagonists toward adulthood.
Why fans should be excited
Nagi Umino and Erika Amano’s relationship has been defined by misunderstandings, humor, and gradual emotional growth. The final arc gives Miki Yoshikawa the space to tie up loose ends — from the implications of being switched at birth to the choices both families will make — while delivering satisfying emotional payoffs and possibly surprising developments for supporting characters.
Quick Plot Recap: The Premise
A Couple of Cuckoos centers on 16-year-old prodigy Nagi Umino, who discovers he was switched at birth. While on his way to meet his biological parents, Nagi bumps into Erika Amano — a loud, headstrong girl who offers to be his fake girlfriend to avoid a forced marriage. The twist: Nagi’s biological parents decide the most convenient resolution to the switch is to arrange a marriage between Nagi and the girl his birth parents raised — and that girl is Erika herself.
Core themes
- Identity and family ties

Manga History and Publication
Miki Yoshikawa, known for works like Yamada-kun and the Seven Witches, launched the A Couple of Cuckoos manga in Weekly Shōnen Magazine in January 2020. Since then, the series has steadily released collected volumes; the 31st tankōbon volume was published in mid-January. The franchise expanded with a light novel adaptation (first volume in 2021 and later volumes following), which adds depth and complementary perspectives to the primary storyline.
Author background and style
Yoshikawa’s strengths are clear: fast-paced comedic timing, expressive character art, and a knack for blending supernatural or unusual premises with grounded emotional arcs. Readers who enjoyed Yoshikawa’s previous titles will find a familiar mix of humor and romance here — but with a fresh central mystery that drives emotional stakes.
Anime Adaptation: Seasons, Streaming, and Dubs
The manga’s television adaptation premiered in April 2022 as part of the NUMAnimation block and ran for two consecutive cours. The anime captured the series’ comedic timing and romantic tension with strong voice work and animation that kept fans engaged across the run. A second season premiered in July 2025, continuing the adaptation of Yoshikawa’s manga with further character development and plot progression.
Where to watch
The anime was streamed globally by Crunchyroll, which also produced an English dub for viewers who prefer localized audio. For the most up-to-date streaming availability, check Crunchyroll’s A Couple of Cuckoos page (external link, nofollow): Crunchyroll — A Couple of Cuckoos.
Key Characters to Watch in the Final Arc
Nagi Umino
The academically gifted but emotionally uncertain protagonist, Nagi must decide how to reconcile the life he was raised in with the family he was born into. The final arc will likely test his sense of self and force consequential choices about his future.
Erika Amano
Erika’s fierce independence masks vulnerabilities. As the arranged-marriage premise encroaches on her life, she must confront her true feelings for Nagi and her own aspirations — a staple of the series’ emotional core.
Supporting cast
Friends, family members, and rival romantic interests have all played roles in shaping Nagi and Erika’s relationship. Expect these side characters to get meaningful beats in the final arc — some providing closure, others pushing the couple toward decisions.
What to Expect from the Final Arc
While specifics remain under wraps, the final arc is likely to:
- Resolve the switch-at-birth mystery and any lingering family secrets
- Bring major romantic tensions to a head — potentially prioritizing character growth over tidy romantic clichés
- Offer emotional, character-driven climaxes and an ending that reflects Yoshikawa’s comedic and heartfelt style
