The Scent of Black Gold (
Desperate to locate oil, Senku says they'll need to take as many aerial images of the area before winter comes and covers everything in snow. With Ryusui and Senku traveling in the hot air balloon and Ukyo and Chrome on foot, they cover as much ground as possible but find nothing yet.
In the mean time, it's harvest season for everyone else and the wheat is collected. With the new food, Francois requests the images so they can find a new dish to make. Francois says they'll make black truffle and pork rillettes, and that they require Suika's help for it since she knows the lay of the land. They find wild boars and using Kohaku, capture them for raising.
Kohaku then scans the images, hoping to find the "black gold" that Francois needs, but instead finds Senku's "black gold": oil. They immediately rush out to try locating the section photographed while Francois and Suika continue trying to find truffles. Unfortunately the moment they find one, the boar they used to sniff it out eats it. They set Chalk on the scent instead, and fewer truffles get eaten.
Struggling to find the puddle of oil, Senku thinks about their options. He remembers that the original Sagara oil field was found by boars rolling around in it. Running back as Francois prepares to cook the boar, Francois notices it reeks of oil, Senku's group frantically return telling them not to serve it yet.
