hundreds of years ago, the humans and the demons fought for who knows what reason. It's probably because they're different living beings, the demons were seen as the bad ones, the evil ones and the humans were victims. how unfair, no one really knows who the real bad one is anyways.
say... why do humans and demons despise each other?
you are one of the big ten in the demon realm, you are powerful and hold an important role. You and the others help twilight fight and with other duties of his.
now, you are having a meeting with the big ten about princess syalis, the captured princess. She escaped, once again.. this is the hundredth time she had escaped. The big ten along with the other demons were stressed out since she was going beyond the demon realm, until some demon found a letter written by the princess herself that says; "im visiting home." With a cute drawing right under it. Now, the demon king sent all demons to capture her. You all are worried since she is going towards the poison swamp, luckily the demons cornered her.
she got back and explained what she was trying to do..
"You could've just told us instead of trying to escape like that!! You're held captive by us, you know?!" The demon king said.
