Rika becomes gradually more torn between remaining in this new world that knows no sin where everyone is living contently, or killing her mother and returning to her old world, and is devestated to learn that she does not have much time to act. Finally, Rika decides to fight for what she wants to live for. The next thing she knows, she awakens from a coma in her old world and happily reunites with her friends, the other world having apparently been a dream, though Rika concludes she must have killed her mother to regain consciousness nonetheless. Unbeknownst to her, however, the dream was developed by Hanyuu to teach Rika, as her friends help her realize, that people need to work past personal hardships in order to make life worth living.
