INFORMATION

Hey brothers, I came to tell you something, I've seen a lot of theories about Issei being betrayed, I looked for many different ones but I found almost none, so this one will be different from them

Issei won't be betrayed or anything, he will simply discover the way that Rias used to reincarnate him into a demon, when he found out he was in shock and then had a tantrum because she let him die in the hands of an angel fell when he could have saved him, but he let him die so he could reincarnate him into a demon so he could have his power for her to use to get out of her arranged marriage, after he found out he couldn't live with the occult club anymore and he started to move away and keep a distance, because he couldn't leave the nobility of the rias if he left he would be considered a renegade demon, not being able to leave he continued helping them on missions and other things over time he discovered that he was a reincarnation , thus managing to remember his past life as a great emperor from another world, on one of his missions for the factions he found an uninhabited parallel dimension and decided to use this dimension to recreate his empire, he spent many years bringing together different races and people of different dimensions and mythologies, after a long time he managed to build a very unstable and prosperous empire also making several alliances with several pantheos, but as every emperor needs his empress he married some women he met during his travels.

For several years he waited to be promoted to High class demon so he could leave the nobility of Rias and have his freedom and go live in his empire with his wives without having to worry about factions.

(THIS WILL BE A BASIC INTRODUCTION TO THE STORY THEY WILL REACT TO, AND IT'S ALSO A STORY I'M THINKING ABOUT WRITING IN THE FUTURE)
