There are rumors of shadow creatures following and threatening people, and one evening Naoya, Tama and her schoolfriends Kim and Haru, see a shadowy figure carrying a bow and give chase.
Tama literally runs into Izumi Marufuji and her two friends, Kaoruko Minegishi and Yuki Takase who all work at City Hall and are also chasing the girl.
He visits City Hall seeking Marufuji, but she and her team have no recollection of the events with the zombies although she does have a photo of the "Pandora project".
Naoya again finds himself in the deserted city where a young woman with long black hair with a bow and arrow saves him from an attack by Hedgehog.
He is attacked by the General and Buta (The Pig) but is rescued by the young woman with a bow whom he recalls seeing on a train platform in his dreams.
Aya destroys Hedgehog and the group enter City Hall where Ikuo Fuyuki explains that Naoya is one of only 12 survivors of an apocalyptic event, and the world he inhabits is created by the mind of Mitsuki who has been kept in stasis.
He awakes to find himself back in the past, living at his brother Ikuo Fuyuki and his wife Miyako's house with his sister Mitsuki and her dog, Hedgehog.
