Synopsis
Kenji Yamaguchi and seven other men and women on Earth were abducted by aliens to a distant star. They are declared by the aliens to "observe you to understand the Eye." In a group life that cannot escape, the only water given to everyone is "water that makes you want to kill people when you drink it." At first, Yamaguchi told himself that the murder urge could be suppressed by reason.

People dry, starve, and die if they don't drink water. What is the little hope you find in unreasonable despair? What is the end of Yamaguchi's bet there? I don't want to kill you! I don't want to be killed! A shocking suspense story.
