the underworld, also known as netherworld in short hell. the world that exists directly beneath the land that we live. demons rule over this land and the ones that rule over those demons are known as demon kings.

the underworld has 4 demon kings. lucifer, leviathan, Beelzebub, Santanas. it is said that these are the names of the demons that originated the demons. in honor of them, the demons started to change their family names into one of these four names once they become the demon kings. and the present four demon kings that rule over this place is the 2nd strongest demon king generation among all the generations that ruled.

demon king Solomon lucifer is the strongest of all the 4 demon kings of the second strongest generation demon kings. the person that wields the power of destruction and the one that recovered the dead body of katsu from the creature that killed him.

right now that demon king is–

*tshhh*

is flying in the sky like human fireworks after receiving a punch.

"How dare you leave all the work here and go to wander offfffff!!!!"

the person that threw the punch was another one of the demon kings

Aoi leviathan, the only female demon king of the present generation of demon kings.

"damn it you idiot, you should've taken me with you. I wanted a fresh breeze as well. it was way too busy. we could've even got a chance to compete"

the one who says that while suppressing the tantrum thrown by Aoi leviathan is one of the two lifelong rivals of Solomon and another one of the demon kings

Dante Beelzebub. the great rival for Solomon lucifer and a great scientist of the underworld.

"now, now, both of you calm down, he would not leave with a serious expression as if he went to the goof-off that right after that magical reverberation. if he did that then he must've had some reasons. right, Solomon? also Dante what do you mean by raking you with him. did you plan on leaving all the work on us as well!!!?"

the one who calmed down both of them and started to complain about Dante was the last one among this generation of demon kings.

Alphonse santanas. greatest strategist and one and only person among the generation with common sense in this group.

this is the new generation of demon kings. the second strongest demon king generation.

Solomon answered the earlier question asked by Alphonse.

"Yeah, you are right Alphonse. you see I went to the source of the tremor that we felt earlier."

"""......?"""

as he said that everybody fell silent and dumbfounded and after reviving from the shock Alphonse said

"wait, did you just say the source of the tremor just now? what was that?"

"If I tell you the entire story you might guess where and what but what shocks is going to be why and how"

"Hey, don't go around the bush. just tell us already"

as you said that Solomon and others moved to a room like a conference place with the four of them sitting around a table with their respective servants standing behind them

Solomon started to explain all of them and they guessed what it was as soon as they learned the source was from the surface and it was actually a human and just like he said they could not guess why and how it was.

as soon as they listened they started talking

"the aura tremor, so the source is one of the monsters that even the strongest generation of the demon kings sacrificed their own lives to defeat"

"the monsters that even the guardians could not make them bow to them."

"the monsters that are the source of the rampage in the underworld approximately 200 million years ago"

"""dragons!!!"""

as all three of them said individually the last word was just said in unison. Solomon nodded and said

"not exactly dragons to be more precise the heavenly dragons. the monsters that are said to be on the same league as god and zodiac guardians"

after Solomon said that everybody became shocked and disbelief. as Alphonse said,

"so you are saying that the host of a heavenly dragon was the source."

as soon as Dante said that then Aoi followed with a huge shocking and disbelief face.

"Are you sure that it is the host? it was not seen until now after the heavenly dragons defeat 200 million years ago a human controlling the heavenly dragon that is. the only rare case that was seen as the child of the host inheriting the power of the dragon when he is born. even people like those were until now only 50,000 were seen until now and only a single-digit were there at present."

Dante said after hearing that

"when a dragon host makes a child the baby born will inherit some of the dragon power but not even close enough to what a host of the dragon could do. but even if they were born the human body is weak which makes them die if they inherit the power, unlike the host who can hold onto the dragon himself that is the reason why there are so many fewer humans that are almost negligible who can use the heavenly dragon's powers. but if it were just a person that inherited the aura from his ancestors that would've not caused any of these tremors then that means–"

as Dante said that he turned his face to Solomon then Solomon nodded and said with a serious expression

"yes, this kid is the host of the heavenly dragon that is inside of him."

suddenly the room went silent with a heavy atmosphere.
