Monster Society

The year is 2030, and monsters are real. That's right, monsters going from demons, spirits, dragons, and a whole bunch more. Although these monsters exist, humans have been hurting and killing them from the beginning, harmless or not. This caused monsters to go into hiding, blending in with the humans which forced them to alter their looks to look more human-like. This didn't last long, as humans learned to lead them out of their disguises. Soon, the government made a program to help these monsters and let them live in peace in a small city hidden from human society, but these monsters have to follow these conditions: They must be in a group of 3-5 monsters, they must listen to their human caretaker, they must not harm their caretaker, and they are not allowed to leave the city.
The main character of this story is a human caretaker, named Elizabeth Hart or Lizzy for short. Elizabeth has always had an interest of monsters and wanted to see if the rumors she hears about them are true or false. Of course, as any other caretaker who volunteered to be a caretaker had to go through training from the government to handle these monsters. The caretakers can choose to have 3-5 monsters to look after. Elizabeth requested to look after 5, which isn't recommended to do alone, but she does. Little does she know the chaos she's getting into and the truth behind these monsters.
