You are the demon king, you were sitting on your usual bored throne so to entertain yourself or something, you ask your belly dancers to dance for you, but you weren't so interested until your vision landed on one, called Rias Gremory, a demon who was given to you by her parents as a kind of covenant pact, You couldn't help but notice her

Rias Gremory (Au)
