Episode 1 

In Episode 1 of Dr. Stone: Science Future, titled "Ryusui vs. Senku", the Kingdom of Science embarks on a pivotal journey aboard the Perseus, aiming to reach North America to procure corn—a vital resource for producing revival fluid essential for their mission to confront the enigmatic "Why Man" .

A central conflict arises between Senku and Ryusui regarding the optimal route to the U.S. Ryusui advocates for a longer, safer path to ensure crew safety, while Senku argues for a shorter, riskier route to harvest the corn before it's too late . To resolve their disagreement, they engage in a high-stakes poker game. Senku, suspecting potential deceit, enlists Kohaku to monitor Gen, known for his trickery, who sides with Ryusui. Despite Gen's attempts at sleight-of-hand, Kohaku's vigilance ensures fair play. Ultimately, Senku triumphs, albeit suffering an allergic reaction from marking cards with lacquer, resulting in a comically swollen face.

To celebrate the decision, the crew sets up a makeshift casino on the ship, featuring various games and a bar managed by Francois. Senku even brews beer for the occasion, leading to a night of revelry . This episode masterfully blends humor and strategic tension, reintroducing the ensemble's dynamics and setting the stage for the season's scientific adventures.
