Ryusui & Gen vs. Senku & Kohaku (RYUSUI (リュウスイ) GEN (ゲン) VS. (バーサス) SENKU (センクウ) KOHAKU (コハク) Ryūsui Gen Bāsasu Senkū Kohaku) is the 144th chapter is of the Dr. Stone manga.


Minami records herself talking about the upcoming poker game between the teams of Ryusui & Gen and Senku & Kohaku. Yo bets on Ryusui winning the game with the aid of Gen’s mentalist tricks, while Ginro bets on Senku’s victory, with Kohaku foiling Gen’s tricks.

As the game begins, Gen scatters the deck and attempts to reshuffle it, but Kohaku interrupts him, pointing out that he had placed the Ace of Hearts at the top of the deck. Gen feigns innocence, and Kohaku asks Ukyo to keep Gen from touching the cards again. The game goes back and forth for a while, as Senku thinks that Ryusui is too gutsy to get a read on. Gen reaches for the cards again, and Kohaku slaps his hand away, having noticed that he was trying to sprinkle something on the cards. Kohaku asks that Gen not move his hands for the remainder of the game. Senku hears a noise coming from Gen’s sleeve, and has Kohaku search it, revealing a beetle that reacts to the sugar Gen tried to place on the cards. When Kohaku asks if Gen has anymore tricks up his sleeve, he says he doesn’t, and invites Senku to investigate the deck.

As Senku is examining the deck, he realizes that Gen intentionally diverted everyone’s attention to the deck, and Ryusui goes all-in. Senku explains that the previous tricks were a grand ruse to allow Gen to replace Ryusui’s bottom 4 cards with an ace four-of-a-kind. Nikki notes that Senku can only beat Ryusui with a straight flush, which she believes unlikely. Senku tells Kohaku the position of three cards in the deck, before going all-in himself. Gen realizes that Senku is diverting attention the same way he did, as Kohaku draws three cards from various points in the deck. Gen asks her if she really drew from the top of the deck, which she affirms. Tsukasa confirms that Kohaku pulled from the middle of the deck, while Chrome questions the practicality of it. Gen and Ryusui can’t find any special markings on the cards, and wonder if Senku is bluffing. Senku and Ryusui lay down their hands, and Senku wins with a royal flush. Gen questions how Senku knew where the cards were, and Senku reveals that he marked the cards with lacquer, relying on his allergy to lacquer to tell him where the cards were. Ukyo declares Senku the winner.
