A Couple of Cuckoos Vol. 26 (Kodansha, 2025)

Nagi and Erika's "home-swap" is off to a rocky start. While the Ama-Umi House is being renovated, Soichiro suggested that Nagi go to live in the Amano household, while Erika moves in with the Uminos. Erika enjoys her first experiences of conveyor-belt sushi and familial harmony, but Nagi finds himself butting heads with Ritsuko, his birth mother. On top of that, Erika runs away after trouble at the Umino house. Will Nagi and Erika be able to return unscathed to the Ama-Umi House?!
