The Cycle Begins

Once every Millennia a strange affliction is spread across Hell where only the sinners of lust are effected. Once it's over the denizens usually go back to their lives but this time around Charlie wants to celebrate the passing of the vicious week-long cycle but she'll need help. Unfortunately Alastor is too busy avoiding the "events" of the cycle so she ends up enlisting the help of a mysterious blue deer demoness coordinator who shockingly looks a lot like Alastor.

Who is this lady and will she be able to make Charlie's vision a success while also fighting off a very...frisky Radio Demon?
