Before Senku and his friends can begin their journey around the globe to solve the mystery of the world's petrification, they're going to need to build a ship and find an experienced captain to sail it. Unfortunately, the sailing expert they've chosen to revive for this purpose is greedy, egotistical, and intends to be richly compensated for his efforts. Now everyone is scrambling to accommodate his demands, leading them to re-create a variety of things needed to build up his wealth - from paper money to a hot air balloon! Before they sail the seven seas, the gang must use the power of science to soar the heavens!
