Dragon's Heart (Highschool DXD x Malereader)

You moved to Japan to join Kuoh Academy. A great school where a lot of great students have graduated from, but you had no idea what was going to become of it.

You moved in with the Hyoudou's, who had a son named Issei that was your age. But within the first week of knowing him, he was nearly killed by a fallen angel, and when you tried to protect him, you were nearly killed as well. However, you were saved by a devil from the underworld named Rias Gremory, but the one downside to this was that you had to become a devil and were now her servant.

Not everything was bad though. You meet a lot of good people because of the world you had been introduced to, and you were now getting stronger with a power that was revealed to you by the devils. You were the Cosmic Dragon Emperor. Plus, you even found out you were part dragon from the dragon living inside you.

Even though this was all great, being a servant to someone else really put a dent in your freedom and it would get you down sometimes. Will you stay like this forever, or will you find a way to break free.
