The underworld.
Inside a castle whose exterior was protected by fifty barriers and claimed to have never been vandalized, even during the civil war,
The castle was called Bael Castle.
"Have the plans of my foolish descendant and those people already begun?" Zekram asked one of his servants.
"Yes, Great King. The demonic power fluctuations of the living weapons created by the original Four Great Devil Kings have enveloped the city of Kuoh and other surrounding cities in the human world."
The servant hesitated and asked. "Should we notify the current Four Great Devil Kings to take action?"
After all, if this matter spread to the other factions that had signed the peace treaty.
The devil faction might be suspected of rebelling and wanting to start a war or something.
But Zekram who was sitting on the sofa casually said, "No need. I already told Eiji-kun and he happens to live in Kuoh city. With him there, we don't need to do anything except send the evidence of the rebels to the current Four Great Devil Kings."
The servant was a little surprised but remembered Eiji who was the fiancée of Rias Gremory, Sona Sitri and had relationships with other famous women in the underworld including the ex-wife of the current Devil King Lucifer.
Even the mother of Sirzechs, Venelana had divorced from her husband and joined Eiji's harem. The woman now shared a man with her daughter which surprised the devils in the underworld.
They were also amazed and envious of Eiji who had accomplished all those feats. But with his power that he had repeatedly demonstrated in the past, none of them dared to seek trouble with him.
Except for the rebels said by Zekram of course.
The bright side was that Eiji had a good relationship with the Devil Faction because of its women.
The servant understood that they had nothing to worry about and said, "As you wish, Great King."
He was about to go and do as Zekram ordered but...
"Wait a moment. Before you go can you turn on the TV and stream the battle taking place in Kuoh city?"
The servant nodded and turned on the TV as Zekram wished.
With the eyes and ears of the Great King Faction in Kuoh city, they could do this.
At the same time.
Eiji was also the topic of conversation of a group of people gathered in a secret room.
Why was it called a secret room even though the location was still in Bael territory?
It was because there were many magic barriers that prevented anyone who was not invited from entering or teleporting into it. Many famous figures in the underworld sat there but they were not the only ones. There were also some representatives from other factions or mythologies that did not belong to the Seven Factions alliance.
They could all see what was happening in Kuoh city from the large screen. If Eiji was there, he would have been speechless and wondered if these people were watching a movie together?
"So this is the power of the living weapons that the original Four Devil Kings created in the past? They look terrifying." Said a handsome man with curly black hair and rare orange eyes. He was wearing a chiton, a tunic-like garment worn by men and women in Ancient Greece and Rome.
His identity was the son of Zeus, the current Principal God of Mount Olympus and the Greek God of the Sun and Music.
He is Apollon!
But unlike in the original work, he is now conspiring with the people in this room to take revenge for the death of his father and his two uncles.
He wanted to kill Eiji Seiya.
He didn't come here alone. There were also two beautiful women sitting not far beside him. They were his sisters, Artemis and Aphrodite.
The men in the room could not help but glance at the women with greed in their eyes. Especially Aphrodite who was the Goddess of Love from Greek Mythology, she was very beautiful and had a figure that could make any man lust.
"That's natural. Their name is Malebranche which is also known as Evil Claws. 12 of them possess power that even the original Four Great Devil Kings fear."
The one who said that arrogantly was the foolish descendant Zekram was referring to.
He was Lord Bael and the leader of the devils in the room. Their group consisted of members of the underworld Devil Council and some clan heads from the remaining 72 Pillars.
But among them, there was also the number one ranked champion in the Rating Game known as the Emperor. He was the strongest devil in the room and was the devil of the Belial Clan, Diehauser Belial.
Most of them united not just to kill Eiji who was considered the biggest obstacle in their goal. However, they united because they were dissatisfied with the peace agreement and wanted to take over the devil faction under their approved leader, Lord Belial.
I don't know which madman instigated their thoughts but they were very confident because they had Malebranche and the gods from Greek Mythology who had more or less the same purpose as them.
For the time being they would work together to kill Eiji and the leaders of the Seven Faction alliance.
"They're that strong? Fufu." Aphrodite giggled and the sound of her beautiful laughter made the men's hearts itch. "I can't wait to see if they are really capable of killing a man who has even killed the Three Great Gods of Greek Mythology?"
Before Lord Bael could answer the beautiful Goddess' question passionately because he was aroused.
"Wait, you said 12 of them but why did I only see 11?" Artemis frowned and asked with a serious expression on her beautiful face.
Lord Bael snorted and said, "Unlike the other 11— the leader of Malebranche, Malacoda is the strongest and his power is much more terrifying than the other members of Malebranche. He's still sealed away somewhere and we keep him as a trump card. But 11 of them are more than enough to kill Eiji."
He did not hesitate to reveal that information to inform the gods in the room that the devils on their side had not yet used their full power. After this cooperation ended, they would have to think twice if they wanted to go to war with the Devil Faction.
Artemis, Aphrodite and even Apollon did not say anything more after that. But no one knew what they were thinking at this moment.
The gazes of everyone in the room were now fixed on the screen. They saw that the 11 members of Malebranche seemed to be talking to Eiji. Unfortunately they could only see and not clearly hear their conversation.
Aphrodite was not satisfied but saw how handsome Eiji was and his power was even enough to kill Zeus, Poseidon and Hades.
Unlike Apollon and Artemis who had grudges in their hearts. Aphrodite licked her pink lips that looked very alluring and thought it would be a pity if Eiji died.
'If possible, I would like him to become my slave rather than be killed~'
Aphrodite did not know she had raised a flag.
...
Back to a few minutes ago.
"We are members of Malebranche. I'm Barbariccia, Deputy commander. You are Eiji Seiya, right?" One of the stone statues flying above the sky spoke.
"That statue can talk?" Iryuka and the other young devils knew nothing about Malebranche.
Naturally, she was surprised that the statue could speak Japanese.
"Still, Japanese?" Rias was more surprised by this and unlike Latia and Iryuka, although she felt a little pressured because of the oppression exuded by the 11 members of Malebranche, she at least still stood calmly.
After all, who was standing next to her?
It was her dear fiancé, Eiji.
Even if the world was about to be destroyed by an all-powerful madman. She felt safe as long as Eiji was beside her.
"..." Barbariccia ignored the words of the girls around his target.
"You are not mistaken Barbariccia-kun, I am Eiji Seiya." Eiji said while holding Judecca on his shoulder.
He didn't take the 11 statues flying in the sky seriously.
But he was a little interested in the motivation and purpose of the people who sent them to him.
With his cosmic awareness, Eiji knew all of that in considerable detail.
[Come to think of it, I've heard of Malebranche in the original work even though I've never read the arc that tells about them.]
Then, how do you know you've heard of them?
The heroines wondered.
[I've only heard of them from Wiki in a previous life.]
Wiki? What is that?
The heroines did not know the site that was very useful for people who wanted to know something but they were too lazy to read the original work.
Eiji was one of those people.
[Rias, Iryuka and Latia didn't know about Malebranche. But that's natural because not many devils know about those toys— I mean the living weapons made by the original Four Great Devil Kings.]
Eiji, you said they were toys, right?
Rias' lips twitched and now she knew that the statues flying in the sky had something to do with devils.
It now made sense that they could exude demonic power.
Still, who had bad intentions and sent them to Eiji?
[As far as I know only the original Four Great Devil Kings and the Head of the Six Houses of Lucifer know. Other than them, there is also a devil from House Nebiros who knows about Malebranche. I don't know how Lord Bael and the members of the Devil Council knew the location where Malebranche was sealed.]
[Perhaps a certain madman informed them and incited them to start a rebellion. They even conspired with the gods of Greek Mythology.]
Rebellion?!
Rias and the heroines in Highschool DxD couldn't help but remember the two terrorist organizations such as the Khaos Brigade and Qlippoth.
But from what Eiji said.
The identities of the people who rebelled this time were different but most of them were well-known in the underworld.
'Why are they rebelling?'
Rias was confused but also had killing intent because they dared to plot against her fiancé.
"We are here to kill you." Barbariccia said indifferently. One of them called Alichino shot a large amount of demonic power at Eiji.
The appearance of the attack was almost similar to the Tailed Beast Bomb fired in the Naruto anime.
Latia and Iryuka froze when they saw the devil attack whose level exceeded the ultimate level flying towards them.
They wondered if they were going to die?
But they almost forgot who the person standing in front of them was.
"Rias, protect Latia and Iryuka. I'm going to exercise a bit."
"Alright Eiji, be careful."
Eiji and Rias spoke casually in that situation.
When the people behind the scenes thought Eiji and the three girls with him would die in the next few seconds.
"Hahaha! I can't believe Eiji was able to block that attack!"
In the secret room.
Lord Bael was already laughing out loud.
The devils and gods who were there were speechless and continued to watch the screen.
Eiji who had been standing in front of the girls moved. He could have used Full Counter to reflect the attacks coming at him, but this time he just slashed with one hand forward.
He didn't use Full Counter and only released one black and white colored slash that cut what looked like a Tailed Beast Bomb.
But after that, the slash continued to widen until the sky above Kuoh city was cut and seemed to be divided into two.
"..." The people behind the scenes.
"..." Rias, Latia and Iryuka.
In their eyes, the attack that looked like it would swallow a quarter of the city did not explode at all.
The attack froze in the sky as if time in the world stopped and when time resumed— the giant black ball turned into scattered particles and disappeared quickly.
[Cooldown is over, Master.]
A female voice was heard from Eiji's sword.
[L'Ciel Cocytus is ready to be used again.]
"That was very fast. Well... Should I use the same move 10 more times to destroy you all?"
Eiji smiled amusedly and said in a voice that was even clearly audible to everyone behind the scenes.
Lord Bael had stopped laughing and looked nervous.
"Wait, 10?" Artemis was amazed by the slash Eiji unleashed. But she again realized what was wrong faster than anyone else.
They all counted the number of Malebranche members on the screen and guess what? They were all surprised.
Even Barbariccia was surprised because at the same time, Alichino disappeared! Their number was now only 10! Their still-sealed leader didn't count of course.
"You are so strong. How did you do it?" Instead of fear, Barbariccia smiled creepily like the statues in Solo Leveling.
They were living weapons that were practically devil versions of Longinus. Their power rivaled the original Four Great Devil Kings and were even capable of killing Gods.
But this guy, Eiji Seiya was able to destroy one of them with a single slash?
"Do I have to explain it to a toy like you, Barbariccia-kun? But fine, simply put it's anti-magic." Eiji held up one finger and explained like certain characters when fighting in anime.
He was doing it just to show off.
Miss System, Leme and Rias knew this.
[I'm the protagonist of Black Clover in this world. Have you ever heard someone shout that I'm going to become the Wizard King?!]
[... It wasn't me who said that.]
Pfft!
The heroines and Rias couldn't help but laugh.
Latia and Iryuka looked at Rias in confusion because why was she laughing?
"Anti-magic? I see."
Not just Barbariccia, the people behind the scenes understood why Alichino disappeared with his attack.
After all, even though each member of Malebranche was made of statues and certain materials. They had magic or demonic power within them that was vulnerable to anti-magic.
It made them realize how terrifying Eiji was.
Although many of them knew he was very strong, this was the first time they learned he had anti-magic!
Isn't that cheating?
One of the devils behind the scenes, Diehauser stared at one of his own hands while muttering "Isn't that a bit similar to my ability?"
Lord Bael slammed his fist on the table angrily. "Damn it! Kill him! We really should kill a dangerous creature like Eiji! The underworld... no, this world doesn't need an existence more terrifying than the Two Dragon Gods. Barbariccia, stop talking and attack Eiji together!"
He ordered Barbariccia who led the other members of Malebranche. Although it was not him who awakened them from their seal in the underground research room belonging to Zaoroma Nebiros. Someone had given him the authority to command them after approving his plan.
Barbariccia could hear Lord Bael's voice inside his head. Without another word, he and the other Malebranche members attacked together as ordered.
Since they knew Eiji had anti-magic, they changed their fighting style to close combat.
Of course, if possible they must not give Eiji a chance to use the same move as before!
"You're all naive."
Eiji said indifferently as the 10 members of Malebranche charged towards him very quickly.
At least from the perspective of Rias and the others because in his eyes, they were slow. Especially after he activated the Rinne Sharingan and extended one of them forward to use the move of one of the famous villain bosses.
"Shinra Tensei." Eiji muttered but everyone heard him clearly.
The law of vibration was also very useful for showing off in this situation.
*BOOOMMMMM!!!*
A very loud explosion made the ears of the spectators buzz.
But what they saw was even more terrifying because after Eiji said that
Malebranche's 10 members and everything in front of him including buildings within hundreds of kilometers.
Everything was blown away.
All of that was driven by an overwhelming and irresistible repulsive force. If one looked from a sufficient height, they would see that half the city of Kuoh and other cities in front of Eiji's palm...
All the things within his attack range had turned into craters.
But what was more surprising. Except for the 10 members of Malebranche, there was not a single casualty because before Eiji released Shinra Tensei, he had teleported everyone involved and some flies to another dimension.
To be more specific, he used the power of Mercurius to alter reality on a worldwide scale.
No one realized this except those who understood the laws of space and time to some extent.
