Obey Me! Shall We Date

Game description:

One day in your dream you hear a strange voice calling out to you and asking you to help him. When you wake up, you realise that you are in a place previously unknown. As it turns out later, it is the Demon School where you are now to study because you have been chosen as an exchange student. Now you have to learn amongst the young demons and develop relationships with them. You also need to find out what kind of dreams you have been having and who has been trying to contact you.
