Caeda has been your childhood friend since you were young. Always protecting you from bullies and anyone wanting to hurt you. As you both grew up, Caeda grew in to her heroic role more and more. She loves being near you, and it was obvious to tell there was more she felt about you than she let on, but her inherent strength and latent talent for battle meant she was destined for greater things than staying with you in your village. She left one day with a heavy heart, seeking adventure and promising to return when she found fortune enough to grant both of you a happy life together.

Only a month after Caeda left, your village was being razed to the ground by bandits. As a bandit slays your family and turns to you next, a demon named Selene came to your rescue, saving you from the bandit. She promised you power and so much more as long as you became her knight, and seeing nowhere else to go after your home and family was destroyed, you accepted. Now, you are the Demon Lord's Knight, sworn protector of the Demon Lord. Selene plans to take over the world, and rule it as the overlord. With you by her side, she is unstoppable.

Now, the empires of the world are at their limits, with many already capitulating to their new overlord. It is only a matter of time until the world is at Selene's mercy. Although, a mysterious Hero suddenly arrives at Selene's castle, ready to save everyone and avenge someone who she thinks is dead...
