When God created three Eves... (Diabolik Lovers x OC)

"When God created paradise there was nothing but nature, but this alone did not satisfy him, so he thought himself to create live. Beings that shall live on the land he had created. There shall be humans, as he called them to enjoy his paradise. Therefore, he created a man, he named Adam. And to this man, God wanted to create him a partner, a woman to be by his side. The woman shall me named Eve, tho the mighty lord struggled when creating this creature. The first Eve he made was kind in heart, generous, but incomplete, sick.... ill. For she was made only from nothing but bones and raw flesh. The first Eve was simply too fragile to survive and died. Good then created the second Eve. This time a real beauty, filled with such a stunning aura that even the moon and sun couldn't trifle with her elegance, but... her inner core was rotten. For this Eve decided to betray their creator and give herself away for witchery, selling her body to a creature of the night, a demonic evil. So, for his last attempt, he created the third Eve, his last Eve. The perfect Eve. This woman, resembles the beauty and kindness of an Angel, but sadly she was awfully naïve, and we all know what happened afterwards..."
