In the 24th Century, Intergalactic Space Travel has become a reality. One of the first outposts in the far reaches of space is WATCHER'S NEST - an inflation hole drive portal - which has recently come under attack by a mysterious force known simply as GHOUL... A group of young female cadets assigned to the portal are unexpectedly thrown into a hornet's nest of trouble as they finalize their training to become an elite pilot in the Seraphim Squadron.

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?!
