Emi and Maou are two powerful beings from another world, destined to be mortal enemies. As Emi the Hero and Maou the Demon King learn to live side by side in a world of technology, science, and rent money, could they also learn to forgive and forget? Could a world without magic be the answer to Ente Isla's ancient war? Could a Hero and a Demon King ever fall in love?

Ever since she was a young girl, Emilia found herself in the care of the Demon Lord Satan. Instead of becoming the gilded Hero of the Church, she becomes Satan's most fearsome Demon General. How will the fate of Ente Isla change henceforth? - AU. Dark, Esdeath-esque Emilia.

A century in the future the Demon Realm is attacked by the Church of Ente Isla, aided by the armies of Heaven. Emilia, now Satan Jacob's Queen, wants to give her newborn daughter a chance at a peaceful life and sends her into the past. Little does the Demon Queen know that her gamble with fate would have serious consequences... - MaouxEmi, LuciferxSuzuno

After two years of relative peace, somethings have changed and somethings have stayed the same. But soon both magic and science will be threatened by a new enemy. Of course, they turn to the one person who's ability has saved them both again and again. But will our Hero's bad luck finally catch up to him and spell his end?

Maou and Emi haven't ceased their feud over what occurred in Ente Isle, and the two are now a bit older, in college, and have found a more deadly enemy than each other: finals! With murderous intentions after finishing a work shift, Emi visits a café, and what, or rather, who, she finds there pushes both of them to the brink. Proof that food makes the world go round!

How will Maou take his first very... personal realization of his nemesis's humanity? Emi really should have bought some tampons.

"If you're not ready to talk to her, that's fine. Relax." The Demon King tries to be considerate to the Hero with regards to her familial problems. One-shot.

They say life is like a cup of coffee. It could either be sweet or bitter depending on how you mix it to your liking. But you also need the right ingredients to get the right taste. Follow Maou as he tries to brew the perfect blend of his life with the hero at the side as his sweetener. (Mysterioustgexpert Challenge)

Instead of disappearing right away, Laylah leaves with Emilia, after her powers awaken and sends Nord away. The hero, raised by her archangel mother, away from humanity and conflict, has to set out on a journey to correct her mother's past actions, while hiding from the angels who are looking for them. How can a morally wrong raised hero save Ente Isla from the demon invations?

While fighting an angel, Maou is sent back to the past and is back in Ente Isla. He not only has to find how to get back to the present, but now he has to take on a second job he would never expect. Keeping up with a child Emi! Warning: Lots of fluff!
