In the future, Utopia has finally been achieved thanks to medical nanotechnology and a powerful ethic of social welfare and mutual consideration. This perfect world isn't that perfect though, and three young girls stand up to totalitarian kindness and super-medicine by attempting suicide via starvation. It doesn't work, but one of the girls - Tuan Kirie - grows up to be a member of the World Health Organization. As a crisis threatens the Harmony of the new world, Tuan rediscovers another member of her suicide pact, and together they must help save the planet... from itself. Source: Viz Media via ANN
