Long since people have discovered Demons exsist. They found their true weakness and killed them all, but not before some were saved by a lone man. He raised the demons like normal humans and never told a soul. When it soon because a burden to keep them he decided to give them away free to the first 5 people who came into his store. Of course people came and went and th demons were bought.
Now, what will happen, will the pets run away? Will they stay? Or fall in love?
Its up to you.
