Death Green (
A silver-coated spear is made for Ginro, who is immediately delighted by the gift. Senku admits they need him as their bodyguard for approaching the sulfur lake. His task is to keep his spear pointed forward ahead of them, acting as a sensor for the dangerous gases that surround the lake. The spear tip will turn black in the presence of those gases.
Scared by Senku's words, Ginro hangs back, walking very slowly until Senku tells him off. Soon, they reach the edge of the spring. Ginro is drawn in by the beauty of the emerald green lake. Chrome notices Senku's hesitation, and Senku responds that the geography concerns him. All the toxic gases are probably trapped in the basin of the lake. Not paying attention, Ginro approaches the lake and his spear begins turning black. Senku yells at him to come back just in time. A few birds fly into the cloud and die immediately.
Kohaku offers to run in and out to gather the sulfuric acid, but Senku tells a story of a researcher who died trying to tie his shoelaces around one such lake. Senku says the only way they can reach the sulfuric acid is to make gas masks.
