Drops of God: Mariage Vol. 4 (Kodansha, 2023)

Mama-miya has made it to the final showdown, but when it comes to the mariage of sushi and wine, their competition has a clear (and unfair) advantage. When Shizuku learns Tohru is the disowned son of a sushi chef, they head to Tohru's hometown in hopes of reconciling with his father…except things don't exactly go as planned. In a twist of fate, the life (and love) that Tohru left behind to pursue wine may hold the key to their way forward.
