This long and bloody series of friendship, faith, paranoia and broken ties seems to be close to ending, as the very nature of the series is revealed: Rika Furude, one of the girls in Keiichi's circle of friends, lives outside the flow of reality, or to be more precise, part of her does, allowing her to not only be a part of each and every "arc" that has taken place, but to view them from a spectator's perspective as well. She has replayed the same events many a time, more times than she cares to admit, and is able to recall such events without fail. Each time, the flow of events is similar, but subtly different, and they all share one thing in common, something she seeks to prevent: her own death in June 1983.
In every past arc, following the events in which one of Rika's friends is overcome with paranoia and strikes out in violence, killing someone near and dear to them, Rika meets her death without fail at the same time, every time. All she wants is to live past June 1983. What's wrong with that?
This time around she has only two weeks to discover who it is who is responsible for killing her, and to prevent it from happening. In addition, she must prevent the events of the past from repeating themselves as they always have, thus causing a massive impact on the flow of the future. As we all know, in the last arc, the Repentance Arc, Keiichi saved Rena from going down the path of insanity and bloodshed and prevented that tragedy, yet somehow did not prevent the death of Rika. This time through, Keiichi is given subtle hints from Rika, the puppet master that she is, to motivate him to change destiny for not only himself, but his friends as well.
During the events of this volume, Rika begins to become depressed, but more than just Keiichi show signs of remembering what occurred in previous worlds, including Rena and Shion, allowing them to further assist in keeping Rika committed to changing the future. Elements of the past begin to rear their ugly heads, but with the fiery anger brought on by such elements will push the heroes of this story to push the boundaries of what is right and what is wrong about society!
