“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!”

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.
