Ryusui vs. Senku (RYUSUI (リュウスイ) VS. (バーサス) SENKU (センクウ) Ryūsui Bāsasu Senkū) is the 143rd chapter is of the Dr. Stone manga.


Minami receives a voice recorder, on which she records the purpose of the Perseus’ voyage, and interviews various crew members, including Tsukasa, Gen, Suika, Chrome, Kasaki, Kirisamie, Kinro, Makazakie and Ginro. Senku and Ryusui argue over which route to take to America. Ryusui favors a longer route following a rhumb line, while Senku prefers a quicker great-circle route. Ryusui believes that following the great-circle route would be too much for a crew inexperienced in trans-oceanic sailing, but Senku retorts that it is viable with the aid of GPS, and that sailing the rhumb line would result in them arriving too late to harvest corn. They would then have to waste another year waiting.

Gen comes down on Ryusui’s side, and Kohaku on Senku’s. When neither of them is able to come to an agreement, they decide to wager the route they’ll take on a game of poker. Gen offers his aid to Ryusui, leading Senku to argue that Gen will (very likely) cheat for Ryusui.

Kohaku joins the game as Senku’s partner, as her keen eyesight will allow her to spot any foul play by Gen.
