Separated from one another, not-so-average-anymore schoolgirl Nanami
and her allies are trapped by the schemes of a mysterious group of
demons that wants Nanami's hidden powers for itself! And to have any
shot at escape, Nanami has to look deep into her soul and get to know
her ancient, powerful side a little better! But a victory in this
battle isn't necessarily the greatest option...getting out of the demonic
trap means Nanami is about to land right in the middle of the intense
war raging between humans and demons!
