The last episode of Dr. Stone Season 4, “Science Journey,” showed François crafting non-alcoholic cocktails for Suika, Tsukasa, Gen, Kohaku, and Senku, lifting the crew’s spirits. Matsukaze recounted the story of his late master to Ginro, adding emotional depth. Tsukasa requested Senku revive Hyoga, and Senku agreed to revive Moz and Homura as well, on the condition they join the crew. After some hesitation, they complied. Chrome, inspired by Viking navigation, created a sunstone with calcite to locate the sun even in poor weather. This invention helped the Perseus crew complete their 40-day Pacific crossing, reaching America at last.
The next episode will pick up right after their arrival in America, as Senku and the team navigate the Sacramento River searching for corn to produce revival fluid. Using moth lights to illuminate their way at night, they will continue their exploration. However, the peace is broken when Tsukasa senses an ominous presence nearby, marking the first confrontation with a new antagonistic force. The encounter will challenge both the group’s scientific ingenuity and their survival skills.

It will be available for international streaming on Crunchyroll the same day, with dubbed versions in various languages such as English, Spanish, Portuguese, French, German, Italian, Russian, and Arabic.
