Previously on Presence of the Supreme Omni God,

Ancalagon - Yup. I just need to warm up for the upcoming Rating game. You see, my host wants to have a Rating game with Sirzech and Rias's cousin, Sairaorg. So I thought I needed to warm up a bit.

Great Red - Yes Ancalagon. I would like to have a duel too.

Ancalagon - Great! Transform to your human form and let's get strated.

Great Red - Yes!

Ancalagon and Great Red descended down to the ground and transforms to their human form.

Great Red - Here I come, Ancalagon!

Great Red rushes to Ancalagon at full speed as his right fist tightens. When Great Red punched, it was only blocked by Ancalagon with his right arm that sent shockwaves in all directions and a large crack beneath them.

The pressure is now felt by everyone inside and outside of the academy.

Koneko - Hey, do you feel that?

Kiba - Yeah. It seems like a duel is happening.

Koneko - Let's go check it out. Who knows what might that be.

Kiba - Alright.

Koneko and Kiba ran towards the hallway of the academy and after a minute or two, they reached the place where the intense pressure is produced. They pant for a while and as they regain their posture, they can see two human-like creature fighting with each other with four wings on their back.

Koneko then looked around and saw Y/n, Rias, Issei and the rest of the leader of each faction, watching the fight intently.

Koneko - Kiba, look there they are.

Kiba - Yeah. Let's go to them.

Kiba - Rias-senpai!

Rias then looked around and saw Kiba and Koneko running towards to her.

Rias - Oh it's you guys. Why did you come here?

Kiba - We came here to check where is that pressure coming from.

Koneko - Say, would you mind tell to us who are they?

Y/n - Oh Koneko, fancy meeting you here. As you can see, Ancalagon and Great Red are fighting.

Kiba - Great Red?! You mean the True Dragon?! He exclaimed.

Y/n - Yeah and why are you so surprised?

Kiba - It's nothing. I can't believe Great Red came here all the way from his home.

Ophis - That's because I called him.

Kiba and Koneko then saw Ophis in which they gasped in shock and Koneko said,

Koneko - O-Ophis, wh-what are you d-doing here?

Ophis - I came here to pay a visit and to meet Y/n in person.

Kiba - I-I see.

Back to the fight

Ancalagon and Great Red were exchanging hard and powerful blows from one another as every punch is causing a powerful shockwaves that can be seen by the naked eye.

When Ancalagon deflect one of Great Red's blast, he countered with his own blast though the difference is they color black and purple.

Great Red then deflect the blast and uses his four wings to create a tornado.

Y/n - Everyone get inside!

All - Right!

Everyone the went inside of the building to be not caught by the large fiery tornado that causes destruction on its way and they continued watching the fight.

While the fiery tornado is heading towards to Ancalagon, he began to absorb it by inhaling the tornado.

Great Red - N-No way.... he can inhale the tornado?!

Ancalagon is now holding his breath and he reaches his limit, he blows it with full force, creating a large flames that destroys anything.

Great Red uses his wings to blow the flames away.

Great Red - Damn... Your gonna destroy the academy if you continued that.

After spitting the flames, Ancalagon then release a smoke signifying that he is already done and said,

Ancalagon - Oops. My bad.

Great Red - With that aside, let's continue.

Ancalagon - Right.

Great Red then roared as he charges to Ancalagon as his fists tighten while Ancalagon did the same. Both of them roared at the top of their lungs while charging to each other. Once their fists collided, it causes a massive shockwave that blew everything in its path. Their fight continues with a fist-fight match.

Y/n - Now that tornado is out of the way, let's go outside.

All - Okay.

Once they went outside, they can see craters everywhere, trees were broken as well as the field, cracks are everywhere and so many more.

Y/n - Damn.... The fight between the Dragon Gods caused a major damage on the environment.

Issei - You can say that again.

Y/n - Hold up, I will fix this.

You then stepped at the center of the destroyed field and began chanting while raising your two hands.

Y/n - Hearken to these words, Hear my cry, I call you spirit from the world tree, I wish to speak to you here, Come to me, Come to the academy, I call you now, Sirona, Wolf Spirit of Restoration.

After chanting, you lowered your hands and then a bright green light appeared in the middle of the field and a spirit emerges from it. Sirona, the Spirit of Restoration. When Sirona touches the ground, a wave of strong wind suddenly appeared that caught the attention of the two Dragon Gods.

Great Red - Hey, what is your host doing in there?

Ancalagon - Ahh. It appears he chanted a spell that can restore any damages along the way. That spirit is named, Sirona, the Wolf Spirit of Restoration. he explained.

Great Red - I see.

Ancalagon - Well, this concludes our duel.

Great Red - Huh? What do you mean? I can still fight more.

Ancalagon - Next time, I promise. We will fight all day, all night.

Great Red - Really?

Ancalagon - Uh-huh.

Great Red - Wow! Thanks! I'm getting bored at my home. I will come to this place from time to time.

Ancalagon - I'll look forward to it.

Great Red - Until then, Ancalagon.

With that, Great Red reverted back to his Dragon form and summons a portal to go back to the Dimensional Gap.

Ancalagon also reverted back to his Dragon form and lands on the field, soft enough not to cause a crater.

Y/n - Oh, Ancalagon. Your here. Where is Great Red.

Ancalagon - Went back home. Nice to meet you, Sirona.

Sirona (angelic voice) - It's nice to meet you too, Supreme Black Dragon.

Y/n - Everyone, this is Sirona, the Wolf Spirit of Restoration.

Sirona (angelic voice) - Hello everyone.

Issei - It's nice to meet you, Sirona.

Sirona (angelic voice) - Likewise.

Y/n - Sorry to interrupt but we need get back to our class, Sirona. Next time, I will summon you and to have a chat with my friends.

Sirona - I'll look forward to it, Master.

Y/n - Until then.

With that, Sirona instantly disappeared and Y/n and co. went back to the meeting while Kiba and Koneko went back to their classrooms.

To be continued...
