"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!"

Michael crossed his arms and asked unhappily, "Gabriel, then what is her purpose? What is this Sarafini who appeared in the sky in the form of a dragon doing?"

Gabriel looked in Raphael's direction and pointed at Raphael in the distance.

"Look at Raphael holding his staff and seriously treating the four injured dragon kings. When the Dragon Queen came to find Raphael, it was to save the injured. So, I guess she is still trying to save the injured."

"You probably haven't forgotten that our ultimate goal is to enter the mythical battlefield to save Davis and the Dragon Princess Lilia. If we don't save the injured, we won't be able to enter the dangerous ancient mythical battlefield."

"I heard that Lilia is the princess that Sarafini dotes on the most. Sarafini must be trying to head to the ancient mythical battlefield as soon as possible, that's why she's letting out such a sad roar."
