Dr. Stone S4 - Episode 5

The episode begins with Stanley tracking down Senku's team and announcing that the "New World" has its first guest: a professional scientist. Chrome and Kohaku observe the enemies, who are apparently using advanced science, and decide to gather as much information as possible. Gen manages to infiltrate the enemy ranks while Chrome establishes radio contact with Senku's team. However, Senku warns that the enemies might be eavesdropping since they are also scientists.

Xeno, the leader of the opposing group, contacts Senku's team and reveals that they have already built a Haber-Bosch facility, allowing them to produce unlimited gunpowder. He demands Senku's team surrender and work for them, or else they will use their superior firepower. Senku recognizes the threat but does not reveal the secret of the revival fluid.

Meanwhile, Suika discovers that an enemy reconnaissance plane is spying on the Perseus's location. Senku decides to convert the Perseus into an aircraft carrier to launch a counterattack. The team works feverishly to build a runway on the ship and prepare the aircraft for battle.

Meanwhile, Xeno plans to defeat Senku's team through targeted intimidation and the assassination of their leader, whom he mistakenly believes to be Taiju. Stanley, Xeno's right-hand man, states that he can carry this out without issue.

The episode ends with preparations for a direct confrontation between the two science teams. Senku sends a special team consisting of Tsukasa, Hyoga, Ukyo, and Suika to capture Xeno and seize control of the resources.
