As head of the Kisaragi Family and the spiritual leader of the Black Roses, Kisaragi believes that both science and foolish men (now extinct) have directly caused the downfall of the human species. Furthermore, if the world is on a course for ruin, the remaining women should simply let extinction run its course rather than look for hope in the science that caused those problems--instead electing to enjoy what remaining life they have.    Kisaragi herself is a product of a genetic experiment, and is half human and half jellyfish. She has pale skin, long white hair, and gills down the sides of her body.

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.
