In a world where nearly all humans have been turned to stone, Senku, Taiju, and Yuzuriha work to rebuild the world. They are currently working on crafting gunpowder when they see smoke signals in the distance. Taking a risk that more humans exist, Senku sends up signals of his own. Meanwhile, Tsukasa arrives to stop Senku from creating gunpowder, and his appearance causes chaos amongst the other survivors.
