King of Heros (Male Reader x High School DXD

"I am Gilgamesh, the King of Heroes! A sovereign whose very existence transcends the limits of men and gods alike. Behold, for I am the beginning and the end, the one who stands above all creation! Every treasure, every weapon, every marvel forged by mortal hands is but a fragment of my vast dominion. You, a mere mongrel, stand before me with delusions of grandeur, believing you are worthy to challenge my supremacy?

Foolish. Laughable. Pathetic.

I do not fight. I do not struggle. I merely exist, and the world bows in reverence! My power is absolute, my will unshakable, and my treasury endless. Know your place and kneel before the one true king, for in this moment, you stand in the presence of divinity itself! Now, prepare yourself-this will be the last lesson you ever learn!"

I feel that the DXD fanfic, stories have started to die out, maybe due to most either not reading the light novels to continue their story, or they realize that most of their stories are the same( Super Duper Op Dragon Sacred gear, I hate issei for no reason, I want every girl in the series to be in my harem) you get the gist. So I thought why not change it a bit, why don't we let all our favorite prideful king go through the world of DXD with a twist, how will he alter the story, I don't know, but I just know it just got better.

I don't own any of the pictures or characters used in this story, besides the OC.
