One of the ancient magic belonging to the hero family that can eliminate demons without quantum artifacts, this magic was once designed by the first ancestor of the Einzvil family, Morgania Einzvil, during the heroes journey to conquer the Fertissio continent 2000 years ago.
Unfortunately she ended up disappearing in a fight against a powerful demon there, no one knows where her body is until now, even her existence is not recorded in any history in this world.
But even so, her descendants still remain and inhabit a remote village at the tip of the Republic of Cestisia to develop ancient magic and practice demon magic inherited from their ancestors.
Then Abigail Einzvil who had long practiced this ancient demon-type magic used to use it to hunt demons on the Fertissio continent as a job from his father.
Which meant, Abigail had never once lost until now when he was in his demonized form.
First, the magic atoms around him detected the bloodline of the ancient hero and adapted the material to the imagination of the magic caster.
The magic atoms slowly formed a substance similar to the stone-like hard skin of a demon in pitch black color, after which it transformed into the form of a pitch black modern battle armor covering Abigail's entire body.
And this battle armor had never once been scratched while fighting the powerful demons of the Fertissio continent.
"The hero family's ancient magic huh! How interesting!"
Modeus, whose adrenaline was boosted, began to chant magic whose base material was light.
Logically, it made sense to fight darkness-type magic using light-type magic, since the two types of magic were completely opposite.
"LASER BEAM!"
Modeus with great confidence in his magic began to fire a very bright laser beam at Abigail, but the attack had no effect whatsoever not even a scratch.
Abigail then launched at Modeus with a hand that was about to reach for his head, but Modeus who realized that moved slightly and avoided a fatal wound.
"Guh!"
Modeus's hand that was taken away by Abigail began to bleed a lot and then the hand grew again after a few seconds.
I can't die even once, it will be bad if my other self starts to remember everything, Modeus thought.
Then with his survival instinct activated, Modeus began to exert his strength and no longer underestimated Abigail, the smile began to disappear from Modeus's face and all that remained was the determination to win.
Abigail who realized that also began to increase his guard, preparing for all sorts of dirty tricks Modeus might come up with later.
"Alright, we'll see who lasts longer, your regeneration magic or my black magic."
After saying that sentence, Abigail suddenly flew upwards quickly and hovered in the air right above Modeus, and Modeus who realized the situation immediately recited his defensive magic.
"Wall, wall, wall, wall, wall!"
"Black Magic: Conscensio Defectus De Terra!"
But unfortunately, Modeus' multi-layered defensive magic was easily shattered like thin shards of glass by Abigail's powerful magic.
After Abigail cast that magic, suddenly under Modeus' feet a pitch-black circle formed which began to emit a kind of dark smoke and covered an area of 100 meters around Modeus.
It was a corrosion-type magic that slowly ate away Modeus's body, as well as everything that came within the range of the magic did not escape the corrosion and began to slowly disintegrate.
"This, this is the first time I've ever felt this!"
Instead of panicking, Modeus who was hit by the magic and began to slowly disintegrate felt a new stimulation.
Modeus widened his eyes and the insanity was clear as day and he automatically started laughing.
"Hyahahahahaha! This is great, this is a masterpiece!"
Modeus's body tried to compensate for the damage and regenerate the shattered parts but still Abigail's magic was faster than Modeus's regeneration.
"It's over, Modeus."
Modeus, who was slowly being dragged into the black abyss full of corrosive substances, looked at Abigail's armor-covered eyes for a moment, their eyes met and finally Modeus was completely lost in the black abyss with a grin still on his face.
Just as Abigail thought the battle was over, suddenly he felt a change in the magic atoms around the black abyss spell.
And as he saw a hand slowly digging its way to the surface as if it wanted to get out of the abyss, there was no mistaking that it was Modeus who was still alive and was struggling to get back to the surface.
Seeing Modeus futile attempt, made Abigail even more annoyed and finally a thick vein appeared on his forehead which was covered by the battle armor.
"You... until the very end!"
"BLACK MAGIC: TENEBRAE STATERA!"
After Abigail cast the spell, a black aura appeared and focused at the tip of his hand then shot like a laser towards Modeus who seemed to be struggling to rise to the surface.
*bang*
The hand that was digging upwards finally broke off, and a lot of fresh blood came out from the abyss like a red fountain.
Finally it was really over this time, as Abigail was thinking like that.
"RIGHT HERE YOU STUPIDDD!"
"Wha-"
Modeus who came out of nowhere was suddenly behind Abigail who was on full alert, Abigail was completely unaware of Modeus's presence who had been behind him.
Modeus launched his fist at Abigail continuously in the air and every time his fist hit Abigail's armor, a tremendous shockwave appeared.
"TAKE THIS!"
Modeus then clenched his fist that he had been preparing with many light-type magic atoms focused on a single point that was his fist, and he launched it swiftly and powerfully towards the face of Abigail who did not have time to prepare any defense spells.
*whoosh*
"GAAAH!"
*bam*
Abigail who took the Modeus' full attack head-on flew deep into the ground and into the hole that had been created by Abigail's corrosion magic some time ago.
But unfortunately, the attack was only able to land Abigail to the ground and did not hurt him at all, there was not even the slightest scratch on Abigail's armor even though it had been hit by Modeus's attack.
Although Modeus planned to put Abigail into the hole he had made and not to hurt him, it still made Modeus's heart ache that his well-prepared attack could not make even a single scratch on Abigail's armor.
"Be buried alive you fool!"
Suddenly, the mass of soil, leaves, and mud around Modeus quickly coalesced and filled the hole where Abigail was and buried him inside.
Modeus used basic control magic to move the surface soil, leaves and mud around him to bury Abigail alive, even though he was only using basic control magic but if used properly then it could also be a deadly magic.
But Modeus was well aware that this was still not enough to stop Abigail with his demon armor, in the end he just buried him alive and the magic armor would definitely be able to get him out of that hole.
"DON'T MESS WITH ME!"
Abigail shouted out from the hole by forcefully blowing up the entire hole and making the ground scatter everywhere, then the veins on Abigail's forehead that were covered by his armor were getting bigger looking at Modeus's resistance that seemed to be playing with him.
Normally no ordinary human would be able to get out of a 20-meter-deep hole after being buried alive just like that, although Abigail seemed to think it was all a game for Modeus who wasn't serious about fighting him.
But the first thing Abigail found when he got out was not Modeus, but a very large blue ball of light floating in the air, the ball of light was so bright that Abigail couldn't see anything.
Abigail who sensed danger then cast a defensive magic frantically, he had never felt such a great danger on the Fertissio continent before and he realized that the magic in front of him at this time was a magic that contained quantum matter.
"It can't be-"
Before Abigail could finish the sentence, the ball of light exploded and shot out millions of tree-sized lasers in rapid succession in all directions like giant blue sea urchins.
"GUAAAAHH!"
Abigail realized that wherever he went at that time, the blue light laser would be able to reach him, he knew very well that he could not escape from a laser at the speed of light.
This is no doubt magic with quantum matter, Abigail thought.
After the huge ball of light slowly disappeared due to the exhaustion of its power, smoke was rising everywhere, making the entire forest destroyed and scorched due to the heat of the light explosion.
The entire surface of the forest had many large holes even penetrating the ground several meters deep and Abigail was lying with his armor destroyed, leaving him with only his human form on the ground, the demon tail and the pair of horns growing on Abigail's head also disappeared when his armor was destroyed.
"How does my genius sister's creation magic feel?"
Modeus appeared out of nowhere behind the rising smoke walking towards Abigail with a grin that widened to mock Abigail who was lying on the ground helplessly.
"But, even that much magic can't kill you, how hard is your damn armor."
"Hmm? Unconscious already huh?"
***
"Huh?"
"Where am I?" said Abigail, who had just woken up in his room.
I'm not dead? But at that time I seemed to have lost my life, Abigail thought.
Abigail was confused because he woke up on a bed in his own room at the Einzvil family residence, after the fight with Modeus.
"You finally woke up too, I was almost kicked out of here by your father for bringing you here in your dying state, you know?"
Abigail who knew that voice very well suddenly turned his side and there he found the presence of someone he hated the most, namely Modeus.
But since he had lost and almost died, especially since Modeus had bothered to bring him home, Abigail's anger was no longer as intense as before.
Abigail, who already knew he couldn't defeat Modeus, decided to suppress his anger and act calmly to Modeus as someone who had lost despite his best efforts.
"Why don't you kill me?"
"I would probably lose all the favor in front of Lord Eliphas if I killed you, after all, he's the one who gave me a place to live here."
"I see, I think you're more of a demon than a real demon."
Modeus who heard that suddenly paused for a moment and looked at Abigail with a serious gaze and then asked.
"Abigail, are you actually a demon?"
"You must be talking about my transformation magic right?"
"Yes, I noticed a resemblance between you and the original demon when you transformed."
"So you've met a real demon?"
"Yes, I have."
"Well, I'll tell you since you defeated me."
Abigail was silent for a moment looking at Modeus who seemed to be looking at him seriously, then Abigail let out a long sigh before continuing his sentence, from the expression on his face it looked like he didn't want to say this to anyone but since Modeus had defeated him so he had no other choice but to answer the question with a heavy heart.
"Actually, my entire family is a descendant of the demons," she continued.
Modeus who heard that was surprised and somehow he felt a strange sensation that made his whole body tremble violently, but it was not fear but a strange excitement that made his curiosity grow.
"Then, what about your regeneration power?" asked Abigail.
"It's a secret," Modeus replied with a sly smile on his face.
"Well, whatever."
Then suddenly a woman barged into Abigail's room with a panicked and hurried face as if a natural disaster had occurred.
"Abigaaaillll, ooh my dear Abigail I heard you were dying!" she shouted.
"M-mother!" said Abigail, surprised to see the woman's face.
After barging in, she immediately jumped on Abigail who was still lying limp on the bed and hugged the poor child tightly as if she didn't want to let go.
"Oohhh Abigail! Who did this to you! I'll go and beat him up, leave everything to mom!"
"Excuse me, it's me."
The atmosphere that had been very noisy was now suddenly quiet and the figure that seemed to be Abigail's mother was staring at Modeus with a killing intent so strong that it gave off a black aura like when Abigail was about to turn into a demon.
"So you're the culprit!" said Abigail's mother with great anger.
Like the fruit that falls not far from the tree, her face was very similar to Abigail's in a fit of rage, large veins appeared on her forehead and horns grew on the woman's head as well as her tail.
However, the number of horns that grew were not a pair, but there were 6 long horns that surrounded the top of her head like a black crown, even longer than Abigail's horns.
Damn, she's serious! Modeus thought.
Modeus sensed a greater danger than when he fought Abigail, the amount of black aura and the density of magic atoms around Abigail's mother was very different from her son's, it was larger and more dense.
"Mother! Hold on, I was the one who started it!" shouted Abigail frantically trying to calm her mother down.
But it seemed like his efforts were in vain, his mother was no longer listening to him and turned into a demon similar to Abigail when he fought Modeus.
"Modeus! Run!" shouted Abigail who was getting more and more panicked as he saw his mother slowly turning into a demon.
Then as Abigail's mother black aura grew thicker, someone came and shouted at her loudly.
"Mira, calm down!" the person shouted.
It was Lord Eliphas and the two little twin girls beside him.
"Lilith, Ophelia hug her!" he continued.
Then the two twin girls ran to hug their mother tightly and screamed for her loudly in her head.
And as expected, as if everything had never happened, their mother who had almost turned into a demon whose level of magic atomic density was far above Abigail's with her full power, now returned to normal and hugged the two twin girls back affectionately.
Is this for real? What just happened? Thought Modeus who was already on full alert and getting ready to cast his defense spell.
And after that the atmosphere returned to the calm it was before, although all the things in Abigail's room had been flying everywhere like a big mess.
***
In a room that seemed to be used for meetings, at the Einzvil family residence.
There were 6 people sitting facing each other and several cups of tea and cakes on the table in front of them.
The interior was luxurious and as usual, with a slightly creepy impression because of the many miniature statues shaped like demons and paintings of death.
It was as if the owner of this house was deliberately displaying to everyone who entered this room that the Einzvil family were devil worshipers.
But the six people in the room right now were not in a good mood to appraise all the artworks there.
"Ehem."
Someone cleared their throat to break the ice, it was Eliphas who felt very stiff in front of his family.
His wife had been staring intently at the boy who had nearly killed her eldest son in an all-out battle.
But it seemed like Modeus who was the perpetrator of all these problems looked very relaxed, even as he munched on the cake in front of him without paying attention to everyone who was staring at him.
"Mom, it's just a misunderstanding, I was the one who asked him to fight," Abigail said soothingly to his mother.
"That's right my dear, it's normal for boys to have their own reasons, look they've made up right?"
Lilith and Ophelia looked at their mother with cute pitying faces, which made her face soften at the sight and then let out a long sigh.
"So, are your issues resolved?" said the mother looking at Abigail and Modeus.
"Y-yeah, our issues are over, aren't they Modeus?"
"Yes, it is."
"Yeah, I don't know what made you fight that badly, but if I see Abigail suffering again..."
"Don't expect you to be able to enjoy yourself like now, Modeus," she continued in a subtle yet threatening tone and from that short sentence everyone realized that she was serious.
"Ne-never mind dear, it's just a boys thing," Eliphas said with an awkward laugh to calm Mira down.
"Hmph!"
"But, I'm really surprised you could get Abigail to that point Modeus, you must be really strong."
"Not really."
Modeus realized there was no hidden intention in Eliphas' words when he said that, he really was a kind and sincere old man, with no intention to take advantage of others like Modeus and no other dirty tricks.
"Modeus's soul has changed color, it's darker than the last time we met, right Lith?"
"That's right! The color is very dark, creepy."
Modeus who tried to hide the truth about his soul could not avoid the demon eyes that could detect one's soul.
Actually, if that fact was discovered it wouldn't be a problem for Modeus either, but he thought that it was best if people didn't know about it.
Because he himself also didn't fully understand his own soul and what kind of creature he really was.
But it seemed that he felt he could not hide it from the demonic eyes of these two twins.
"I'm not the Modeus that you guys know."
