Boarding School Juliet Vol. 4 (Kodansha, 2018)

All Romio Inuzuka wants is to wish his secret girlfriend Juliet Persia a happy birthday, but when Inuzuka's authoritarian older brother Airu suspects their relationship, the star-crossed couple's plans-and their confidence in keeping up their mad masquerade-all go down the tubes. Luckily, Persia's big day isn't over yet, and Inuzuka has one last chance to fool his big bro and meet up with her…it just happens to involve roping the Black Doggies into “crashing” Persia's birthday bash at White Cat House! Commence Operation: Pie Persia!
