Omniversal Travel

The group arrived in front of a huge mansion whose size exceeded even that of some castles.

"It's huge!"

"This is the president's house?"

"Welcome home, Miss Rias. And her guests too."

Grayfia was the one who came to welcome them personally.

Although she dressed and behaved like a maid, she was actually Sirzechs' wife, so she had a very high status.

The group entered through the entrance and found a long line of servants on both sides of the hallway who inlined as they saw Rias walk past them.

"Rias-neesama! Welcome!"

A crimson-haired boy came running up to Rias before giving him a tight hug.

"I'm home, Milicas!

You've grown so much since the last time I saw you."

"President, this child is?"

"He's my brother's son."

"So he's your nephew?"

"Come on, say hello."

"Yes!"

The boy approached the group behind Rias and greeted politely.

"I'm Milicas Gremory. Nice to meet you."

"How Kawaii!"

"He really is a prince."

"Gentlemen, please come in."

Grayfia opened a door and gestured for the group to enter.

"Rias Onee-sama came home!"

The first to rush in was little Milicas, running to embrace a brown-haired woman dressed in a white dress.

The woman stroked his hair gently.

"Long time no see, Venerana-sama."

The first to greet was Akeno, who then bowed slightly, followed by the others.

"How nice that everyone is well. It's good to meet the new members.

I am Rias' mother, Venerana Gremory."

The woman introduced herself before approaching the group and looking directly at Noah with a look of judgment.

"You must be Noah right?"

"Oh, you know me your highness?"

"Haha, no need to be so formal.

I always pay attention to Rias' potential suitors. I am his mother after all.

I have to thank you for last time. You taught my husband a good lesson. After all, he chose a fiancé without thinking about his daughter's feelings."

"Mother!"

"Well, let's go to dinner."

"Rias' guests, please make yourselves at home."

They all had dinner and chatted before going to sleep in their room.

The next day, Azazel gathered the whole group in the garden of the mansion.

"Well, it looks like everyone is here.

I made a twenty-day training plan.

Noah, we'll start with you."

A huge silhouette landed behind Azazel.

"He'll be your personal trainer."

"This is the first time I've trained a Ddraig bearer."

"I want you to use your Balance Breaker during training.

Even though you have it pretty much mastered, you haven't completely mastered it yet."

"Good."

Noah nodded before flying to Tannin's shoulder and off to a distant location.

Akeno appeared somewhere overhead as he looked up at a man with a rough beard.

"Why are you here?"

"Long time no see, Akeno."

"Don't call me by my name so lightly!"

"You should accept the blood that runs in your veins.

If you use the inner power of the fallen angel, you can use the light of your thunder to create lightning."

"So...that's what you wanted."

"This is an order from the ruler.

I never expected an order to train my own daughter."

"You don't need to hold back!"

Suddenly, Akeno's body glowed before her clothes changed into a Shinto priestess dress.

"Do you understand the meaning of these clothes?

It means...I don't have a father."

...

Elsewhere, Yuuto brandished his heavenly demonic sword while recalling Azazel's teachings.

"Perfect your Balance Breaker and stay in that state as long as you can."

Suddenly, someone appeared behind Yuuto.

"Hmp. It's quite a pleasure!"

Similarly, everyone began their own training.

On the other side, an intense battle ensued between Noah and Tannin.

One was tiny while the other was huge but still, the shockwaves of their battle could disintegrate the bodies of those weaker.

The battle between the two dragged on for three straight days as Noah was improving his control over his Balance Breaker and increasing the time it could be used.

After a while, the time of use of the Balance Breaker was over and Tannin left.

Noah also got up and left the place, teleporting to the outside of the mansion.

After a long shower, he entered a room.

It was Koneko's room.

She had been acting weird lately and even fainted during training due to exhaustion.

She was now lying on the bed, with a worried look on her face.

After a long talk, Noah left the room, leaving Koneko alone.

He then rejoined the others.

"Today representatives from several families will have a party.

I have to leave.

I'll send someone to come get them."

Finished speaking, Azazel left the room.

"This is an event that serves to increase relations between young demons.

As servants of the president, we can't do anything careless."

In the evening, the group dressed formally and entered the party.

Sirzechs met with Azazel.

"Michael should be here soon."

"I left Baraquiel in charge of security, and according to him, Odin should be on his way here."

"Baraquiel is protecting him?"

"Just to be on the safe side. There are many Nordic gods who do not approve of Odin's alliance with the demons."

Sirzechs sighed.

"We always seem to have people like that in every group."

"The problem is that the Khaos Brigade is recruiting such people."

Khaos Brigade was the name of the terrorist organization that caused the previous incident, and their forces were only increasing every day.

...

"I've never seen so many demon king level demons gathered in one place."

"This is an incredible sight."

"Try not to offend anyone...eh?"

Before Rias could finish speaking, everyone felt a shiver that gave them goosebumps.

From the weakest of the weak to Sirzechs himself who was standing not far away.

They all felt a strong murderous intent and their instincts screamed at them that something very bad was going to happen.

Suddenly, everyone turned to look at Rias' group, or more specifically, the person who was releasing such monstrous murderous intent.

"Balance Breaker."

Red armor covered Noah's body and the boost notifications began to go off like crazy.

Purple flames covered his draconic wings and the green spheres on his armor also turned purple.

"Amalgamation transformation!

Transformation of the god demoio!"

Black runes covered the entire armor before reorganizing into a pattern of black flames that ran throughout the armor.

Boost!

Boost!

Boost!

The strength doubling alarm didn't stop sounding until Noah's strength doubled tenfold.

"This power...it's the equivalent of a demon king using his full strength."

Azazel watched the scene with interest.

Noah walked slowly towards one particular person who was standing with a group of young demons.

The others were frightened by the murderous aura that distorted the space around them and moved away, leaving only the kindly looking young man in the center.

"Diodora Astaroth, do you have any last words before you die?"

"Hey kid, what the hell are you doing?"

Suddenly, a green-haired man stood in front of Diodorah and shielded him from Noah.

It was his older brother, Ajuka Beelzebub, one of the four current demon kings.

With a backhanded blow, Noah sent him flying before grabbing Diodorah by the throat.

"Your crimes are many, but I honestly don't care about any of your so-called crimes. Today you are destined to die because you dare to try to lay your hands on one of the people of my clan.

But since I know that murdering you here without any explanation would cause a lot of trouble for my hosts, how about we give them a valid excuse so that your brother will have no argument to try to save your miserable dog life?"

Ajuka Beelzebub rose from the ground and his aura burst forth and he was about to charge Noah when two equally strong auras exploded in front of him, blocking his path.

They were Sirzechs and Seraphall.

"Why don't we hear about your brother's alleged crimes first? Then we'll decide."

A third aura blocked over Ajuka. It was Azazel.

Under Noah's strong grip and tyrannical aura, Diodorah found it impossible to resist.

"Truth spell."

Noah touched Diodorah's forehead with his finger and the latter began to speak.

He started talking about all his secrets, about how he liked to recruit nuns to play with and mentally break them, about how he planned to approach Asia to make her his new plaything. But this did not matter to the higher demons but they paid attention to Diodorah's next words.

"I secretly murdered the previous heir of the Glasya Labolas clan."

With her words another demon king aura suddenly burst forth. It was the current fourth demon king, Fabius Beelzebub.

He was a member of the Glasya Labolas clan and the previous heir was directly related to him by blood.

With one more demon king aura locking onto Ajuka, the latter could only suppress his rage and could only watch as Noah questioned Diodorah helplessly.

"Tell me, where did you get your snake from?"

A small snake coiled over Diodorah's arm.

"It was given to me by Ophis-sama after I joined the Khaos Brigade."

"Well gentlemen, there's my excuse.

Is it enough to justify my next actions, Sirzechs?"

"Yes, don't worry, now the Astaroth clan has to answer to everyone and take the consequences of their heir's actions, they are in no position to debate."

"Right."

Tightening his grip, Diodorah's neck snapped and Noah secretly absorbed his soul.

Though he knew he would garner the animosity of one of the four demon kings with his actions, he didn't care.

His burst of strength earlier was a clear message that he was not someone weak and that his strength had reached, at the very least, the level of a demon king.

Grabbing the black snake, Noah crushed it as well.

"Hey! That's got some serious research value!"

Azazel complained.

"I know, but this thing is too dangerous."

"You know what it is?"

Noah nodded before explaining.

"This is a serpent of Ophis, they are a manifestation of his power.

It's the same snake that consumed Katerea Leviathan in her confrontation against you to increase her strength.

While that bunch of idiots think they're smart and think they can use a dragon god to their own advantage to gain power, they don't know that this thing has all sorts of hidden countermeasures."

Shaking his head, Noah scoffed at that bunch of fools from the Khaos Brigade, who thought they were using Ophis for their own benefits.

Nullifying his transformations, Noah returned to his group.

The four demon kings also left, they had to discuss how the Astaroth clan planned to compensate the Glasya Labolas for the death of their previous heir first before talking about other things.

On the other side, Koneko suddenly raised her head before rushing off towards the elevator.

She ran out of the building and into the forest.

"I'm sure I felt her..."

"Long time no see, Shirone..."

A woman lying on a tree branch greeted Koneko.

"As I thought... Kuroka-neesama..."

"I just sent some of my ki and you came through. Your Onee-chan is very touched."

"Nee-sama, what does this mean?"

"Don't make that scary face. I heard you were having a big party. So it peaked my interest a little. Nya."

"Hey Kuroka! Aren't you done yet?"

From the bushes, Sun Wukong's descendant, Bikou, appeared.

"Nee-sama, because..."

"I came to take you with me. Ophis and Vali will be happy to accept you.

After all, you have the same power as me coursing through your veins."

"I am part of the Rias Gremory family."

Koneko's gaze was steady as she looked at Kuroka.

"I will take you by force if necessary."

"I'm afraid that won't be possible."

Suddenly, a voice was heard before two people appeared in the sky.
