"Reincarnated into the World of Magic as a demon, the last thing Davis expected was to grow up right amidst the arms of angels. Ever since the group of philanthropic angels took pity on his miserable birth and adopted him, Davis has been forced to keep his evil identity a secret while he signed in to the system. 
""Ding! The Host has signed in at Angel's Pond, 'The Saint's Halo' is rewarded!"" 
""Ding! Devil's blood activated. Sign in error. 'The Devil's Curse' is additionally rewarded!"" 
""Ding! The Host has signed in at God's Throne, 'Gold's Holy Axe' is rewarded!"" 
""Ding! Devil's blood activated. Sign in error. 'The Devil's Manifistation' is additionally rewarded!"" 
After a thousand years of quietly signing into places in the City of Angels and being rewarded with double the rewards, Davis's true identity finally came to light! Now as a true Devil, Davis had both the world of angels and demons surrendering at his feet!"

That ancient angel's eyes were like torches.

At the same time, they also felt very ashamed.

Davis was disregarded by them just because one of his wings was broken.

As the administrators of Paradise Island, those archangels really did a terrible job.
