Via the long-distance warp known as the "Exodus Project," Worns, Ryer, and the rest of the "Watchers Nest" crew manage to flee Earth. Misaki, who was engaged in the final battle with "Ghoul" at that time, is not present; instead, she witnesses the Earth transform and become sealed by a time barrier. Ryer and the others search for a way out of this space-time maze, but the Earth shifts into various forms. Countless "Nows" emerge due to diverging time axes. Furthermore, Misaki, who should have vanished as a result of the Exodus Project incident, remains. Before Ryer and the others, different versions of Misaki appear: the Misaki from her training school days and the Misaki from her childhood. Are these reflections caused by the conflicts within Misaki? She awakens a second time and realizes that history is now heading in a completely different direction. Will Misaki, Ryer, and the others be able to find a true happy ending?!
