an anime sequel to Divergence Eve. It follows smoothly from the previous series. The characters are the same and the plot is similar, but the theme of the episodes is much different. In this series, the elite team at Watcher's Nest is traveling through time, fighting the Ghoul at different points in time during Earth's history, mostly in Japan. There's also some discussion about the fact that the different times to which they are traveling may also be different versions of Earth, on which the time-line is slightly altered. This series is also distinct from its predecessor in that it is more plot- and character-driven, with less in the way of fan service.
