The situation looks grim-until he runs into his science-loving friend Senku! Together they plan to restart civilization with the power of science! Senku, Chrome and Magma go spelunking for a rare mineral they need to create cell phones! But can they handle a real-life treasure dungeon and make it back alive? And will having an edge in communications give Senku the decided advantage he needs over Tsukasa?
