After Lost Christmas, the First Apocalypse during which many people are infected with a virus, a boy, Shu, gets caught up with girl Inori of the terrorist cell Funeral Parlor who are fighting the United Nations (GHQ).
Later Shu is forced to fight Funeral Parlor's leader, Gai, who wants to create a new world in which selection and evolution are simultaneously imposed on everything and everybody. Gai needs to use Inori's body to resurrect Mana, the original Eve.
The second part (ep 12-22), which starts when many students and some former members of Funeral Parlor are trapped inside the "infested" zone, was by far better than the first half. Music-wise some interesting choices, with piano music reminiscent of Evangelion.
