Ep. 5: Senku devises a plan to deploy a plane while the science crew coordinates with scouts to capture Xeno.

Chrome and Kohaku observe the enemy base and confirm Gen’s infiltration, prompting a brief call to Senku that is cut short to avoid detection. Dr. Xeno contacts them using their frequency, mistakenly identifying Taiju as the scientist. Taiju confronts Xeno about the danger of machine guns, but Xeno reveals a Haber-Bosch plant for mass-producing gunpowder. Taiju refuses to share revival fluid secrets, leading Xeno to end the call. Stanley flies a nearby plane, proving Xeno knows their location. Senku plans to convert the Perseus into an aircraft carrier to deploy the commandeered plane. The science crew deduces the scouts' location via radio timing to target the factory and cornfield. Hyoga suggests deploying a team with Tsukasa, Ukyo, and Suika to locate Chrome and Kohaku and capture Xeno.
