In a big room, the demon kings have gathered. the room is more like a cave with runes written on the walls. there is a flat slab in the center of the room with runes written on it and a door made of stones with the continuation runes written on it that are connected from the slab. and there are four symbols on the stone door and four holes that are adjacent to them.

"Alright, let's unlock the door that is connected from the slab"

as Alphonse says that everybody passed their magic through the slab then beams of light in dark red, dark blue, dark green, and black color aura released from their respective bodies. as their bodies were lit up. the runes on the slab started to glow and the aura was passed on through the runes that are connected from the slab to the door and eventually passed on to the four symbols. as the aura was passed on the symbols started glowing in four different colors.

red - lucifer

blue - leviathan

green - Beelzebub

black - Sathanas

these are the people with their respective colors of the aura. after the four demon kings confirmed that their four symbols were started to glow they went to their four respective colors and inserted their hands adjacent to their symbols and passed on their magic into the door and then the door opened.

as the door opened a sudden bright blinding light came and filled the entire room with that bright light. everybody closed their eyes due to the bright light. the source of this light is a small orb.

lucifer opened his eyes and took out his hand out of the hole and reached to the orb and removed it from the place.

"now that we opened it. let's get to the business"

Aoi that

"but man~, this much unlocking is way too much"

Dante started complaining as Alphonse explained it to him

"But you can't complain. this is the greatest item that can only be created by the creator rank of the light, zodiac guardian rank - 2. he compressed his immense amount of mana for 5 million years to create this orb. that is the reason he gives it to every kingdom only once in 5 million years including hell and heaven. once a land receives one, that land does not receive it again until after it was given to all the other kingdoms in the other 5 million years cycles. to be more precise it is the cycle does not repeat until others were given. and we were the last to receive this from him until the celestial creature's invasion took place. other kingdoms might still have this who received one from before us. but for us, this is the last line of defense to protect this piece."

when Alphonse said that, Dante replied with a troubled face

"yeah, I know all that. and here we are using this to reincarnate a human."

as Dante says that lucifer replied to him

"remember Dante. we are not just bringing a human back to life. what we are bringing back to life is the hope of this world and the savior of the universe"

"yes, yes"

as Dante was saying that Aoi asks Solomon

"so, where is this hope of the world you are talking about?"

"yeah, my servants are on their way and bringing him here."

as Solomon mentioned that Alphonse started to talk

"but if elders find out about it they are definitely going to be mad at us. well, at least we should consider ourselves lucky. they might stop at being angry at us since we are their favorite but if it were others they would definitely be executed horribly."

Alphonse is explaining it with a scary voice to others as they were smiling wryly at that explanation.

"my lord we brought him."

" here you go, master."

while they were talking like that the servants have brought the body of katsu covered in a magical transparent film to stop his aura from leaking.

"Yeah, thank you for your hard work. so could you bring him and place him on this slab."

""yes""

when he asked them they placed him on the slab where the runes were written. and-

*rustle*

they removed the magical transparent film, the instant they remove the film a red aura leaks out of his body suddenly with pressure which made the demon kings get shocked and the servants have cold sweat running through their cheeks.

"What a dense aura"

Aoi says

"it can even surpass our aura"

Dante says

"if he could control it then we could really win our 100 million years of stolen freedom."

Alphonse says

for all those Solomon replies with a serious expression

"It is still too early to celebrate. this kid still has the heavenly dragon in him. that is for sure, but the aura he is releasing is not his. it is the raw aura of the heavenly dragon. but we don't know yet whether he can control it or not even before we can let him train him. well–"

after saying that lucifer rests his hand on the chest wound of katsu and continues

"we will know it once he is back to life"

he feels the wound on the chest with his hand while continuing to say

"his heart is literally punched out."

as Solomon says that Aoi replies

"poor kid. must've had a painful death"

then Dante talks

"of course he would be. he was just a human when he died right?"

"any way we should begin the ritual"

when Alphonse says that everyone takes their position. three of the four demon kings positioned themselves in three positions as formed into a triangle when connected. Solomon was in the middle holding the miraculous sphere.

all the three demon kings standing in the position of the triangle positions release aura at the same time and says a chant in the unison

"""Light which posses the power life, fulfill our wish a swear on the life."""

after their chant magic circle with a pattern is formed with three of the demon kings in a circle and all the circles are connected by a large circle and the three demon kings are connected by a triangle internally in the circle. right in the middle of the big circle katsu's dead body and Solomon are present.

then Solomon takes the miraculous sphere and places it right inside the chest hole and then when he places it he makes the wish

"the savior of the universe, on the request of the 4 demon kings, I ask you to come back to life as a demon"

after he made his wish the entire circle on the ground shrinks and makes itself into the size of the chest wound. then a bright light rises from his chest and increases steadily and rapidly and covers the entire island.

in the middle of that bright light that was still covering the island. the dead body of katsu rises freely, slowly, and steadily into the sky. the red aura which was flowing out of the body after the film was removed gushes out even more amount with huge pressure. the aura that gushed out of the body changes into the form of the red dragon silhouette covered in red aura rises within the light and roars

[ROARRRRRRRRR]

after the red dragon appeared and roared the demon kings were frightened and stepped back and got on the guard and their respective servants came before them and took the stance of the battle as if to protect them but they were clearly afraid and were shacking while a cold sweat was dripping from their forehead.

as the red dragon was roaring the aura diminishes little by little and katsu gains a pair of black wings on his back and a pair of red dragon wings without a definite shape and color from the same spot. the dragon aura and the dragon shape and the light reduce and little by little before vanishing.

after the entire thing has settled while the 4 demon kings and their servants were watching it in surprise and fear while being on the guard. a cold sweat has dropped from their cheeks as katsu has landed on the slab. the chest he had before was gone. they could hear his heartbeat and breath heavily. but Solomon has a painful expression on his face it was different from fear. it was as if he experienced something mentally painful.

the first to snap out of the fear was Aoi. as she asked while she was still looking at katsu

"what…. just happened here?"

"did I just see a heavenly dragon with my own eyes? I have never seen a real thing and was that dragon in red?"

as Dante followed Aoi while he was still looking towards katsu and asking questions with a confused face with a smile while cold sweat was still running through his cheeks.

then Solomon answered his question while still looking at katsu with the same painful expression.

"That was one of the heavenly dragons, red dragon, the child of the sun"

then Alphonse answered happily as there was still sweat on his forehead and while still looking at katsu

"so…. he really is… the hope of the…. world"

just when the 4 of them were still surprised and talked the servants were still shaking while staying on the guard in front of their kings respectively. everyone was a little bit excited except for Solomon he was still looking painful.

"uh–"

as they were all looking, katsu slowly opened his eyes and woke up from the sleeping position on the slab. as if he was waking up from his bed. he woke up and sat on the slab he looked at the surroundings and his eyes met with the four demon kings and their servants. their servants were on guard as if they were protecting the demon kings while they are clearly shaking in their hands and legs. their expression is of that fear was well.

as they were all on the guard the first thing that katsu say is–

"who…. are you… people?"
