The cloaked figure just glanced at him and replied. "During his final moments, we were able to alter the effects of his spell by some miracle-"
"Altered!?"Everyone was shocked, but the cloaked figure kept going ignoring the interruption.
"-he should be able to only use 1% of his power at max until he's 18, at that point, he will gradually get his power back. We can decide what to do with him in that time we were given.

In a small house in Ankronchia, a woman was in the process of giving birth with a man trying to calm her down on the side holding her hand.
"It's ok dear, the doctors said it should be over pretty soon." He tried to keep calm while trying to calm her, at the same time trying to stop the tears coming from out of his eyes.
...
Moments later the woman is holding her newborn baby in her arms breathing slowly. "He's beautiful, dear. My sweet baby boy."
"Mhm *sniff* *sniff* look at my boy." The father letting streams of tears roll down his face. "What should we name him, Yuri?" The father wiping his tears away, finally asking.
"That's right, his name." She then adorned a thoughtful look on her face, before coming to a decision. "Hmmm... how about, L-"
"Daemon. My name is Daemon."
Before she had a chance to finish, she was interrupted by the soft, but unshakeable voice of the newborn in her hand, who's body rapidly grew every second until it stopped at about the size of an average-sized 12-year-old boy.
"EEEEEEHHHHH" Both of the parents yelped in surprise due to their newborn transforming into a 12-year-old boy.
The boy ignored them and put on a thinking expression.
'It seems that the reincarnation spell actually worked. I mean, I was pretty sure it was going to work, but since that was my first time using it on myself I had my doubts. Somethings wrong tho, Why did my age progression stop at a 12-year-old boy, I was aiming for 18. It seems someone tampered with my power.' He came to the conclusion merely due to the fact that his aging stopped at a 12-year-old boy... there's also the fact that the area around him wasn't destroyed just by him being there.
'I guess I can worry about that later tho, I need to deal with these two.' He suppressed his thoughts as he looked at his 'mother' and 'father'.
'I guess, I'll just start this off casually' But before he even got the chance his father burst into tears once again.
"MY BOY IS A GENIUS! HE CAN USE MAGIC JUST AFTER BEING BORN!"
'...'
"Hello, my name i-"
"HE CAN EVEN TALK, HONEY!" His father interrupted him once again.
*sigh* 'I'll deal with this later.'
...
A week had passed and his parents just labeled him as a genius, choosing to just assume him calling himself the Demon King was a way of him looking up to the Demon King and wanting the same title as him.
During this time he was trying to find some way to get his original power back. When he studied his body with his mana he noticed something resembling a chain locked around his soul, and it left him with only 1% of his power.
'How did this happen tho? Even tho I have never tried this reincarnation spell out to its full effect, I have gotten rid of all of its negative effects, the only thing it required was a sufficient amount of power generated in his final moments as the main component. Wait, could it be that I didn't generate enough power at my final moments?
'No.' He quickly got rid of that thought. 'I was attacked by all 7 of them at the same time at full power, the dogs(the gods) even used that forbidden technique that sacrificed trillion... the only possible option left would be...them.' As he said that uncontrollable bloodlust could be seen in his eyes, but there was also a hint of sadness.
'Even to this day, they still want to interfere in my life...'
