Venna Borimia is the Archbishop of Nezzerath Church of Debauchery, who also serves as the vessel of the very 'goddess' she worshipped, Nezzerath.
After finding out that she was transported into an entirely different world, Venna pledged to once again reenact her dearest savior's church to its former glory and spread its obscene teaching to the new world.
"What kind of cruel gods dare to say indulgence in one's lust is a bad thing? I, the Archbishop of Nezzerath Church of Debauchery shall welcome you with my arms open... Or, should I say, with my legs open, fufufu."
