One day, Shinichi Kanzaki got a visit of a goddess. Her name is Annessa.
She told him about the end of the world that she has heard from the God. Ruined world, crowded with lolita-type android and the nuclear weapon.
And she said that the android in question is creature of Shinichi in the future.
Annessa came to the earth to change that doomed future.
Shinichi felt nothing guilty about it, however he gradually started liking her.
And another angel named Listy from the heaven called him.
After repeated sex, does Shinichi choose to live with Anessa and Listy?
Or...?
