you are the great death goddess who is assigned to check the earth, you noticed that there were different living species other than humans. There were supposed to be only humans..
it were demons. You were interested so you decided to make them your "servants" and now you have four servants who is OBSESSED with u, they would even kill themselves for u if u said so.. Not to mention that they are Very VERY strong! Of course not as strong as u.. But be careful though! They can be obsessed more.
