Dr. Stone

Synopsis

While recalling the time he was first revived by Tsukasa, Gen is suddenly attacked by a mysterious assailant, barely managing to survive thanks to fake blood bags he had protected himself with. Learning that the culprit was Magma, who believed that Gen was a sorcerer instead of Senku, Kohaku reveals that Magma did so to win the Grand Bout, a tournament Kohaku has previously beaten him in to keep him from marrying Ruri and becoming village elder. As Kohaku, Kinro, and Ginro train for the Grand Bout, Gen gives a false report to Tsukasa after Senku promises to make him a bottle of cola.
