Tracking down the secrets concerning Kana's death has led Yuko "Yasako" Okonogi into a new series of virtual rabbit holes. Like Alice through the looking glass, Yuko discovers that the digitally augmented world on the other side of her glasses is far more complex and confusing than she could have imagined. With shocking e-spaces filled with mysterious un-erased levels of data, and virtual creatures that act and think as if they're truly alive, how many other secrets might these parallel worlds hide? Who is responsible for hiding them? As new memories from her past begin to surface, she must now confront whether the e-spaces themselves are somehow affecting the real world and how this involves the "other" Yuko. Their destinies may be intrinsically linked as the real and virtual worlds collide in the climactic conclusion of DEN-NOH COIL!
