Through the long distance warp called the "Exodus Project", Worns, Ryer and the 
other crew members of "Watchers Nest" manage to escape from the Earth. Misaki, who 
was attending the final battle with "Ghoul" at that time, isn't present there and 
before her eyes, the earth changes and gets enclosed by a time barrier. 
Ryer and the others search for a way to escape from this space time maze, but the 
earth changes to various forms. Innumerable "Nows" appear due to varying time axes. 
And also Misaki, who should have disappeared because of the Exodus Project incident, 
still afortiori. Before Ryer and the others, different forms of Misaki appear. The 
Misaki from training school, the Misaki from her childhood days. 
Are these reflections caused by the conflicts that exist inside Misaki? 
She awakens a second time and when she derives the response, that history is leading 
into a completely differnet direction now. 
Will Misaki, Ryer and the others be able to find a real happy end?!
