A True Dark "Lord" (Futa Oc x Female Harem)

(so this will be an Attempt story but I will also see if it can rival with my Strategy of nazarick book if you know what I mean but yes I hope you enjoy this story I don't own none of the characters or anime) in this there was another Leader of Nazarick besides Momonga that was Susan or in game they call her Sauron the Dark "lord" of Nazarick and Mordor which the only way to get to it you'd have to get pass the near to final room at the throne room there you would have to see if you could match or even defeat the Dark "lord" army's and guardians there it would be entirely impossible nearly due to how much there is one of the main reasons why the Administrators asked Susan does she want to be a Raid on certain events which she was given many things to which everyone in Nazarick respected her greatly and are best friends with her however what happens when they are transferred to a new world with Momonga...........
