One last challenge stands between Shizuku Kanzaki and his father’s fortune-to identify the wine his father called “The Drops of God” in his will. Problem is, he’s up against Issei Tomine, a famous wine critic his father adopted shortly before his death. Alone and penniless following his journey around the world to gain knowledge and train his senses for the final showdown, Shizuku stumbles into a western-style izakaya to work for food and a place to stay. But when Shizuku uses his newfound smarts to save the struggling business, a competing chain launches an identical menu and enlists the help of a rising sommelier to go head-to-head with them. In order to stay on top and survive this brutal business, it all comes down to perfecting the food and wine pairings—the blissful mariage of flavors which delights the senses.
Shizuku and Issei go head-to-head in the Four Course Challenge, vying for key components of the Drops of God. The officiers, however, seem to have their own motivations when it comes to voting… What’s more, with every new mariage, Shizuku questions what his late father saw in Issei and not him. After the decisions are made, Shizuku is called upon by an old rival to help lend polish to an Italian bar on the brink of closure.
