When an alien bomb powerful enough to destroy the entire planet sticks to the buttocks of Shin-chan's pet dog Shiro, a race to save the world begins.

Set in the ruins of Tokyo in the near future, a small group of female survivors face the impending extinction of humanity. They are forced to use violence in the face of bioterrorism and other threats. While some women accept their fate as the last generation of humans, others see biological engineering as a final hope for the survival of the species.

By A.D. 2010, all men have died off quickly due to a dramatic change in the environment and an unknown contaminant. The population decreased to the lowest number ever seen...until only the women were left alive. They live huddled in small corners of a world mostly reclaimed by nature. There are those who accept their inevitable extinction and live a carefree life... There are those who try to continue on the race with the help of science... It is a society of constant conflict over their differences of principles and policies. The story takes place in the center of Tokyo. It is one of the places left for them. The conflict over the specimen of ICE and the chance it may provide to save humanity begins
