This is a rewritten version of my other book, The Demon Kings. Your character will be pretty much the same but less powerful. This story also starts in the first season unlike my other book where I made up what would happen next. Also I heavily apologise to people who wanted me to continue the old book but I think the story would flow a lot more easier if I started in the first season as well as it being easier to introduce characters like Raynare into the harem. I do not own any characters from both Blue Exorcist and Highschool DxD or your own character. Thank you.

What would happen if one of Ainzes old friends was also transported along with him and sees the merciless monster he has become...
