After escaping Shakespeare's divine play, Akane, Midori, and Aoto find themselves inside the zone. Aoto already holds the key to the Gate, but Akane and Midori do not. Unfortunately, Loki already has that figured out, and great tragedy awaits the two.

With "despair" being the key to the Divine Gate, both Akane and Midori's loss of their significant person tragically gives them access to the Gate as well. However, Aoto is up for more despair as he faces his twin brother, Ariton.
