Blue Seed 2

The Aragami conflict should have ended with Susano-o's return to sleep, but attacks in San Francisco and at TAC headquarters bring Momiji and Kusanagi back into danger. These creatures do not follow the rules the team once understood, and their trail points toward a dangerous human experiment.

TAC travels to the United States to uncover the source of the new monsters. Valencia, a woman with powers resembling Kusanagi's, joins the turmoil and complicates Momiji's feelings as well as the investigation. Stopping the threat requires understanding how science has revived an enemy everyone believed defeated.
