I like 'Eternal Struggle, Eternal Love'. In this fanfic, the demon and angel are reincarnated throughout different lifetimes. Each time they meet, they fall in love again, but their different natures always create problems. It's a great read for those who enjoy a bit of a tragic love story with a touch of the supernatural.
Once upon a time, an angel named Ariel was sent on a mission near the demon realm. There, she met a demon named Damien. Against all odds, they fell in love. Their love was a secret, for it was forbidden. But they couldn't resist each other's charm. They would meet in a hidden grove between their two worlds. They shared stories, dreams, and slowly their love grew deeper, defying the laws that separated them.
There was a demon called Zephyr. He was not as cruel as the other demons. One day, he rescued an angel, Lyra, who had fallen from the sky during a celestial battle. Lyra was injured and Zephyr took her to a safe place. As Lyra recovered, she got to know Zephyr better. Zephyr showed her that demons were not all bad. Lyra's presence also made Zephyr want to be a better being. Soon, they fell in love. Their love story was full of challenges as their two worlds were at odds with each other. But they held on to their love, believing that love could bridge the gap between the demonic and the angelic.
One popular theme is the struggle between good and evil within the relationship. Since angels are typically associated with good and demons with evil, their love often challenges the norms of their respective worlds. For example, they might have to hide their relationship from their own kind. Another theme could be redemption. The demon might be on a path to redemption because of the love of the angel. And also, the idea of forbidden love is very common, as their love goes against the natural order of their existence.
The contrast. Demons are often seen as dark, mischievous or evil, while angels are pure and good. When they fall in love, it's a clash of two completely different worlds. It's like Romeo and Juliet but with a supernatural twist.
Once upon a time, there was a demon named Damian who was tired of the chaos in the underworld. One day, while on the surface world, he met an angel named Aurora. Despite their different natures, they were drawn to each other. They had to hide their relationship from both the heavens and the underworld. Eventually, their love was so strong that it started to change the way the two realms saw each other, bringing a bit of peace.
One of the well - known characters could be Castiel from the 'Supernatural' universe. He is an angel, and there are many fanfictions that pair him with various demons in interesting love - related scenarios. Another could be Aziraphale from 'Good Omens'. He is an angel who has a complex relationship with the demon Crowley, and this has inspired a lot of fanfiction writers. And of course, there are many original characters created specifically for different 'angel and demon love fanfiction' stories.
One common theme is forbidden love. Since angels and demons are supposed to be on opposite sides, their love goes against the natural order. Another theme is redemption. Sometimes the demon is redeemed through the love of the angel. For example, the demon might start to do good deeds because of the angel's influence.
Another ending could be that they fight against all odds and change the views of their worlds. The demon becomes more like an angel and the angel understands the demons better. They are then accepted and live happily ever after together.
The ending could be a happy one where they manage to convince both the angels and the demons to accept their love. They could become like ambassadors between the two worlds, promoting peace and understanding. So, instead of seeing each other as enemies, the angels and demons start to co - exist, all because of their love.
