Sirzechs dead? Diodora shows his power!

Seeing the shock on everyone's faces, especially Grayfia.

Diodora smiled faintly, he didn't rush to answer and glanced at Keterea in the distance who seemed unable to defeat Serafall like in the original work.

The devils of the Old Satan Faction and the Magicians too, they were unable to hurt the likes of Grayfia, Serafall, Michael and even Baraqiel.

What a waste.

Yet he was neither surprised nor disappointed because from the start he had known these people were completely unreliable except to buy time.

That's right.

Diodora had not intended to rely on Keterea and the people she brought with her to kill the people here because he knew it was impossible.

They were too weak...

And as he said before, he was only using them to buy time until he finished dealing with the Sirzechs and did the rest by his own hands before those people managed to get out of the Alternate Space he created.

After all, it was not impossible for them to force their way out of the Alternate Space as long as they focused their attacks on a single point in the sky. With the power of Grayfia and the others, they could definitely do it.

That's why Keterea and the people of the Khaos Brigade were needed to temporarily distract.

Feeling the power flowing within him that according to the system had entered the ranks of the five strongest beings in the world of Highschool DxD, he was very happy and of course he had already finished dealing with Sirzechs.

How did he do it?

Let's go back to a few minutes ago before Sirzechs fell into the trap he set.

...

"This..." Sirzechs who had just fallen from the sky had a shocked expression as he recalled the series of things that had just happened.

Time in the previous conference room suddenly froze, everyone froze for a moment. But for people as strong as himself and those at least in the Ultimate Class, the ability to stop time at that level was incapable of stopping it.

At most it only slowed down his reaction slightly and that was enough to make him react late when the portal suddenly appeared under everyone's feet.

"Looks like everyone was transported to a different place."

"Whoever planned this, their intention was clearly to separate us and it was done to make their plan easier."

"Let me guess, they must be planning to kill the three faction leaders and the people present at the conference."

Looking at the dense forest around him and the dark sky with no stars or moon. Sirzechs who had hundreds of years of combat experience, especially on the battlefield which earned him the title of the Strongest Devil in the underworld.

He didn't panic, his face was very calm. He also didn't worry about Grayfia, Serafall and the others because he knew they were strong although not as strong as him not many creatures in the underworld were able to hurt them.

"But Rias... Is she okay?"

About his younger sister, although Sirzechs knew in the fight against Kokabiel, his dear younger sister showed the power of an Ultimate Class Devil that was slightly worse than his.

He was still worried... People in his family and his wife often called him Siscon because he was too fond of his younger sister.

He was proud of his younger sister for growing up that strong at such a young age, but when he found out Rias got that power because of a boy named Eiji Seiya.

Sirzechs was a little unhappy. Not knowing why, he always compared Issei and Eiji, and he always thought that Eiji was not as good as Issei.

So he didn't have a good impression of Eiji even though the boy wasn't that bad for his younger sister.

At this moment, he had been walking randomly and thought people would jump out of the darkness to attack him or something.

Although he was walking very casually, he always kept his guard up and did not let his guard down.

Also...he wondered who was doing all this to them?

"Onii-sama! Onii-sama! Help me!"

"Huh? Rias?!"

Because he was Siscon, Sirzechs naturally lost a bit of his composure when he heard Rias's voice asking for help.

Looking around where it was dark and covered in many trees made it difficult for him to determine where Rias was. He was annoyed and had the urge to blow up this entire forest with his Power of Destruction.

However, he quickly canceled that idea as he was worried that his attack would also hurt Rias.

He opened his wings and flew towards the direction Rias' voice was coming from, the voice only sounded once, and when Rias stopped calling him it only made him panic even more.

He was worried that something had happened to his younger sister!

Although his younger sister was now strong, she might have gotten into the enemy's trap deeper and experienced something bad.

But when he arrived at the location, landing in the middle of a rather large patch of grass, he saw no one.

His younger sister was nowhere to be seen and the most conspicuous thing in the place was a small red and white ball about the size of a baseball.

"I remember this thing was supposed to be called a Pokeball. Rias has several versions of this as a display in her room."

"Is this a joke?"

Sirzechs frowned. Who would dare to make a joke like this with him? I don't know what the other party's intentions were, Rias' previous voice was also definitely fake.

As he held the Pokeball in his hand because he didn't feel any danger from it. It was really just a toy...

Sirzechs did not realize, however, as his attention was distracted by the Pokeball. The shadow under his feet slowly expanded abnormally.

By the time he felt something was wrong.

"Sirzechs-sama, why are you here?"

Someone came out from within the darkness, Sirzechs naturally looked back vigilantly.

"You... Diodora Astartorh?"

Sirzechs was startled, although he was also still alert, his attention was distracted and his body stiffened as numerous black chains wrapped around his body accompanied by a tremendous suction power as if sucking his soul and strength appeared under his feet.

As he looked down, he saw a strange dark hole that held him in place!

He had trouble moving his body, not even his power could be exerted!

Diodora's laughing voice rang out and said, "Sirzechs-sama, I didn't expect my little trick to completely fool you. Just like in the original work, you were caught off guard if it had anything to do with your sister, Rias. Hehe it's funny to see that the Strongest Devil in the underworld can be defeated with just this trick."

"Diodora! What are you doing? Let go of me! Do we have any enmity?" Sirzechs was angry and humiliated, he did not understand why the heir of the House of Astartorh would do this to him.

It seemed that everything that happened was planned by the young man.

But he did not understand why the other party would do this, especially when Gremory and Astartorh's relationship was so good. After all, one of the Maou of the Astartorh family, Azuka Beelzebub was his best friend.

So he did not understand why of all people, Diodora was targeting him.

Also, what is the original work? Diodora seems to know how much he loves his sister to be able to distract him with things she likes.

"No, we don't have that kind of enmity in the first place."

"Then..."

"But Sirzechs." Diodora stopped pretending, he called Sirzechs without caring about the difference in their status and said: "Actually, not long ago I joined an organization called the Khaos Brigade. I'm sure you are familiar with the name of the most famous terrorist organization that wants to rule the world. That organization is actually led by one of the Dragon Gods, Ophis."

"Not only that. In the plan to kill everyone in this peace conference between the three factions, the Old Satan Fraction also joined the Khaos Brigade."

"The one who led this attack was originally Keterea Leviathan and those people are now dealing with your wife, your sister, and the others."

"--!"

Sirzechs was dumbfounded to receive so much shocking information in one breath, he wanted to say something. Like negotiate or something, but Diodora raised his hand towards him and said. "Too long, let's speed it up. Devour."

"W-Wait! What the..."

Before finishing his words, the suction that sucked away his soul and power grew stronger as a familiar hole also appeared in Diodora's hand.

Sirzechs felt his vitality and strength being absorbed! He didn't know what method Diodora used to kill him, but he was definitely trying to break free while screaming because it was extremely painful.

Even for a devil dubbed the Strongest Devil, the feeling he felt right now was more painful than anything he had ever experienced.

The feeling of his soul being ripped apart and his power being sucked away was extremely uncomfortable.

In just 5 minutes, the Strongest Devil in the underworld, Sirzechs Lucifer lost all his vitality. His body dried up, looked hideous, and slowly turned into ashes. Even his ashes were not given a chance, it was also sucked into the hole created by Diodora's devouring ability.

Bang!

Instantly, there was an explosive sound like shackles being broken from Diodora's body.

"Hahahahah! This is it! This is it! This power! Now I have it!"

A red and black aura exploded from his body, it covered all the alternate space he was in.

Sensing that the space was about to be destroyed, Diodora did not drown in his happiness after devouring Sirzechs' power which made his possess devil power and mastery of elemental destruction higher than before.

He remembered that there was still a lot of quality food for him to devour.

So he quickly moved to another place.

...

And here he is now.

He snapped his fingers, instantly Caludia and all his peerage members appeared behind him.

"Diodora-sama, sorry. We didn't manage to kill Rias Gremory, Sona Sitri, and the other two."

"That's fine. Hurry up and drink the Phoenix Tears."

Diodora waved his hand, handing out the many bottles of Phoenix Tears that he kept on hand to all his peerage who were injured quite badly.

He frowned, it seemed that if he did not immediately forcibly move them to his side, they might already be dead.

Caludia and the rest of his peerage had bloody wounds on their bodies.

It made him wonder if Rias, Sona, and their two Queens were that strong? There was a hint of anger in his heart when he saw his people injured.

He would ruthlessly kill heroines like Rias and the others. And it just so happened that besides moving all his peerages, he also moved Rias and the others here.

So everyone was now gathered.

However, he was a little surprised to see Rias who was wearing black armor and a drill-like weapon that he had never seen in the original work.

Sona too, although she looked the same. Just like Rias, he also felt power fluctuations no less than Ultimate Class Devils like Serafall and Grayfia from her.

What about Akeno and Tsubaki? Both seem to be the same as in the original work.

"Everyone..."

Although she didn't know who transferred her here so easily, Rias seemed a little happy that she was transferred to the place where Grayfia and the others were.

Sona and the others were the same. However, everyone's focus seemed to be on the others instead of them.

"Isn't that Diodora?" Sona wasn't surprised, after all it wasn't long ago that she knew that man was also allied with the people of the Khaos Brigade.

She was just confused as to why the situation here seemed to be a little wrong and almost everyone was staring at Diodora with surprised and wary gazes.

Especially Grayfia, Rias saw the woman staring at Diodora with a very surprised expression and her expression hardened slightly as if something bad had happened.

"By the way where is Onii-sama?"

Rias looked around, she thought her older brother was also here, but she didn't see him among these people.

Instead of answering her question, she heard Grayfia yelling at Diodora.

"Diodora, answer me! What the... No. How can you use the power of destruction?!"

"What did you do to Sirzechs?!"

Rias widened her eyes. Something happened to her older brother?

In fact, Grayfia was also unsure if Diodora had anything to do with Sirzechs who she had yet to see.

It was just that when she saw Diodora appear while throwing the power of destruction, she had a bad feeling.

Although when he arrived Diodora also shot people from the Khaos Brigade, she didn't think the other party was on their side because the power of destruction he used made her suspicious.

No matter where he looked, she felt that this Diodora actually had bad intentions towards them.

The corners of Diodora's lips lifted higher when he heard the silver-haired woman's question. He gave her a funny look and said, "Clever woman... Grayfia Lucifuge. You immediately guessed that I had done something to your husband?"

"Hehehe that's right. I, Diodora Astaroth have killed Sirzechs Lucifer!"

"!!!" Not only Grayfia, but Serafall, Michael, Baraqiel, and Vali who were more ignorant than usual were also surprised to hear this.

Keterea was also surprised, she looked at Diodora in disbelief, but seeing that the other party could somehow use the power of destruction to kill her people made her dissatisfied.

She didn't know what Diodora was doing, but did he really manage to kill Devils like Sirzechs all by himself? It made her a little excited that their plan didn't seem to have completely failed!

"No way! Diodora, you're talking nonsense!"

Rias didn't know what really happened, but heard Diodora dare to say she had killed her older brother. Although her relationship with her brother was currently rather bad, but she was still very concerned about her brother's safety.

There was no way she would stay silent when someone said he had killed her older brother. Killing intent flashed in her eyes, just like the people who previously wanted to kill her, Sona and the others, she certainly did not hesitate to kill people like Diodora who were clearly collaborating with the people of the Khaos Brigade.

!

Under everyone's gaze, Rias' body disappeared as the ground beneath her feet shattered into pieces and her figure suddenly appeared directly in front of Diodora with a black drill that glowed with the light of destruction.

"Diodora-sama!"

Claudia and his other peerages panicked, but Diodora signaled them with his hand to stay behind him and his other hand created a crimson magic circle that was familiar to everyone.

It was the magic circle of the House of Gremory!

"You guys don't seem to believe that I killed Sirzechs. Let's see, actually besides killing him. I have also absorbed his power with a certain method and this is the result!"

Diodora grinned, he did not panic, before the Rias drill-like weapon containing the power of destruction was about to hit him. He also fired the power of destruction from his hand and it collided with the other party's attack.

Boom!

"Rias!" The people who had a relationship with Rias panicked.

A crimson explosion within a 300 meter radius containing the power of destruction was created and shone brightly in the area where Rias and Diodora were facing each other. The wind blew strongly, the ground crumbled into nothingness and everyone who knew the horror of the power of destruction naturally moved away from the center of the explosion.

When the dust still lingered in the air, a crimson-haired figure was thrown out of the smoke. Rias was the one who was thrown and seemed to have lost the battle of power so her body was thrown several meters.

Fortunately she looked fine, her armor was able to provide her with a magical defense so strong that the previous explosion was not enough to hurt her.

However, Rias' expression looked ugly, she was also shocked and dazed that Diodora could actually use the magic circle of the House of Gremory and could even use the Power of Destruction!

Recalling what Diodora had said earlier, Rias's face paled slightly, her lips trembling...

Was what Diodora said true?

Her older brother... Did he really die at Diodora's hands?!

"Just this? Although I don't know where that armor mode and drill-like weapon came from. Rias Gremory, you're stronger than I thought."

"But to defeat the current me? That much power isn't enough."

Diodora shook his head under the admiring gaze of his peerages and the men of the Khaos Brigade. The latter seemed to forget he had shot several of them dead before.

As for the others? Diodora moved all his peerages to a place further away from him. Why? It was because after Rias, Grayfia flew high in the sky and created ice meteors out of thin air filled with dazzling silver runes.

Absolute Zero!

"Diodora Astartorh, I want you dead!"

For the first time in hundreds of years, Grayfia was furious, knowing her husband had most likely been killed by Diodora and her power somehow absorbed by that man.

The fire of revenge blazing in her icy heart, she used her strongest attack without hesitation to freeze the other party to its soul and destroy it.

Diodora certainly did not stand idly by as he saw the huge ice cube hanging over his head, he smiled coldly. Unlike before, this time he threw the flames he got after devouring several Devils of the Phenex Clan. With his current devil power, he was able to manipulate the hellfire of the Phenex Clan's Devils so that it was no worse than his previous attack.

It was just that to deal with Grayfia's ice elemental attacks, he used the fire element which was more effective against ice.

People were surprised again when they saw that Diodora could also use the special ability that the Devil of the Phenex Clan possessed.

Knowing Diodora had a certain method of absorbing and gaining other people's abilities.

They wondered how much power Diodora had absorbed in addition to the special abilities of the Devils of the Gremory and Phenex Clans?

If Diodora could acquire the special abilities of other supernatural races as well as much as he wanted...

This ability is too underhanded and terrifying!

This kind of person, even without Sirzechs' death, there are many people, especially supernatural beings in this world who would want to kill Diodora because of the abilities he has.

Boom!

Golden-red flames that were no less than ice meteors collided with each other. The place was once again hit by an explosion, and this time the explosion created a white vapor that almost covered half of the small dimension that Diodora created.

In this situation, the veteran people certainly did not remain silent. Having seized this opportunity to slap Ketherea into an ice sculpture and kill her on the spot. From the beginning Serafall had no trouble killing Ketherea if she was serious, and now she was serious.

"Serafall! Ah! I'm not reconciled!"

Ketherea howled before her body shattered into pretty icy dust. Serafall did not give Ketherea an extra glance, she was now staring at Diodora seriously. She was also angry that Sirzechs, her best friend had been killed by Diodora.

Raising her hand high into the sky, a giant light blue magic circle was created, seizing this moment, she also attacked Diodora with her strongest attack.

Celsius Cross Trigger!

Michael also attacked the same person with a giant golden sword made of holy power that descended from the sky.

Baraqiel summoned holy lightning.

After hesitating for a moment because he didn't really care about Sirzechs' death, Vali also attacked. He knew Diodora was strong, so he activated his Juggernaut Drive without hesitation and shot out a silvery white aura that was actually a concentrated and stronger version of Half Dimension.

Rias who was previously silent also attacked again, she shot dark crimson energy from the tip of her weapon.

Sona, Akeno, and Tsubaki were the same. They attacked Diodora simultaneously with their respective powers.

Sensing that people were smart enough to attack her in this situation, Diodora stopped smiling, she was expressionless and said with some annoyance.

"It's true that this world is very dangerous. If you don't have strength, you'll only die when bullied by these people."

"Unfortunately it's not me."

"You guys think all these attacks are enough to kill me? Poor thing..."

Rumble!!!

Not the explosion from all those attacks, but from the explosion of the power of the devil within him that was no longer held back and was unleashed all over.

A terrifying red and black energy came out from Diodora's body and it created a force field that expanded until it slapped away the attacks from various directions aimed at him.

Somehow when he hit the force field, all the attacks were swallowed up as if they were absorbed.

Everyone was dumbfounded of course.

Not only that, a terrifying oppression that made Ultimate-class creatures like Grayfia, Serafall, Michael feel their bodies heavy also emanated from Diodora.

This power... Diodora has reached this level of power?!!

Crack!

There was the sound of glass shattering and it seemed to be because the alternate space or small dimension they were in was unable to withstand Diodora's strength so it collapsed.

At this moment, everyone returned to the underworld, right in the courtyard of the building where the peace conference was previously held.

"Hahahaha! Did you guys see it? Feeling scared? This is the power I've reached now!"

Diodora started laughing out loud, he was no longer cautious, he had completely let go of all his arrogance after transmigrating all this time and made everyone desperate just by sensing his power.

Grayfia bit her lip, although she still felt very angry and wanted revenge for her husband's death. She was not stupid, she knew just from the oppression coming from Diodora, that man's strength was much stronger than hers and it seemed to be slightly stronger than Sirzechs.

Rias too, her eyes reddened and looked at Diodora with hatred in her eyes. She knew she and everyone else here seemed like none of them could defeat Diodora.

Feeling desperate, she suddenly remembered someone who was very strong and might be able to help her.

She took out her D-Dial and called someone.

Who was that person? Of course it was Eiji!

"Eiji! There's a problem! C-Can you help me? No, I mean us!"

Everyone and even Diodora naturally looked at Rias.

Seeing the girls' faces suddenly change as if remembering a hero, Diodora was curious who exactly was the person Rias had called to deal with him?

Strangely until this moment Rias had never once called out the protagonist's name.

"Understood, I'll go there in 2 seconds."

A magnetic and masculine male voice sounded, Rias hung up the phone with an expectant look while looking around.

Diodora wanted to say something but at this moment his instincts suddenly screamed to run! No, it was actually his system that was screaming!

[Host, run as fast as you can! You must leave here right now!]

"Huh?"

He was confused, this was the first time he heard his normally emotionless system suddenly show emotions called panic as if afraid of something.

This made the originally confident Diodora a little nervous.

Is it too late to escape?

The man behind the phone said he would come in 2 seconds!

And now 3 seconds have passed!

"So where are the reinforcements? It looks like he didn't come. Rias Gremory, the man you called seems too cowardly to come."

Diodora sneered, his system was too paranoid. Even if the person to come is very strong, with the help of the system and his devouring ability, he doesn't need to be afraid of the other party!

Rias, Sona, Grayfia, Serafall and the others began to worry.

Michael looked around with an interested gaze and by the way he was also looking for Gabriel!

Where is Gabriel?!

And Vali? He looked at Diodora Astartorh with a sympathetic gaze.

"That man is dead."

"That's right, Vali. I advise you not to follow that fool. Better not to provoke that man even though I know you suspect him of killing Azazel..."

Albion said that mentally to Vali and the latter fell silent as if deep in thought while clenching his fists.

At this moment, there was the sound of coughing and rapid footsteps.

"It's a bit later than I said, I need some time to bring these people.

"By the way Gabriel, can you let go of my hand? People might misunderstand our relationship."
