What Season 4 of Dr. STONE
After resolving the crisis of the Petrification Kingdom, Senku and his companions prepare to fight the being responsible for the phenomenon, which is believed to be on the moon. Building the spaceship requires resources and a great deal of manpower spread across the planet, so the Kingdom of Science team sets sail on the ship Perseus toward America. There they discover that their rivals control what they need and have technology just as advanced as theirs. Senku must prevail in a scientific duel with Dr. Xeno, while Stanley and Ryusui complicate every step of the journey.
