Issei gulped hearing all of that, as he now realized that Supernatural World, as it was called, was filled with existences that could wipe out entire countries in a matter of seconds if they wished to do so.
Indeed the Supernatural World of the Draconic Deus was a ruthless place, where those with strength reigned supreme and did what they wished.
The only reason they rarely fought on Earth or acted there was a silent agreement between all factions that they wouldn't destroy Earth as it was the source of Faith for many Pantheons and the source of Souls and other resources.
"Right now, I will show you how the fights in the Supernatural World are fought."
Rias stated as she signaled for Shirone to follow her into the building.
They entered together into the abandoned factory, where the criminal devil named Viser was obviously hiding. It was dark here; Rias and Shirone took the lead, while Akeno stayed with Issei in the backlines, as they wouldn't be fighting.
This was a relatively high-level fight, and Issei could quickly perish here, considering that he was only a Low-Class individual.
As they were searching through the abandoned factory, suddenly, several thunderbolts were shot at them, to which Rias cast a defense barrier that protected them all from incoming magical attacks.
Akeno subsequently cast an illumination spell, illuminated the entire abandoned factory, and showed the culprit they were searching for.
It was Ultimate-Class criminal Viser, and she looked like a hybrid between men and centaur. She had a voluptuous upper body with long, black hair, and her lower body was gigantic and beastly with four legs, each having sharp claws and a snake as a tail.
"Criminal Stray Viser, by orders of the Commissariat, you are hereby sentenced to death for murdering 17 guards, escaping the prison transport, and for the original charge, casting a forbidden ritual that sacrificed a life of tens of Imperial Citizens in order to reach Ultimate-Class. I Rias Lucifer-Gremory, Novice Executioner of the Execution Temple, will carry our the Judgement."
Stated Rias in a formal voice as she observed Viser carefully.
Stray Devil was a term used for devils that cast a forbidden ritual to increase their strength by sacrificing others quickly. Though not the valid reason for that name, but rather each of these rituals had a terrible side effect of transforming the recipient into hideous monsters with grotesque shapes and looks.
The moment Rias finished the sentence, she instantly created several orbs with her Power of Destruction and shot them towards the Viser. Despite her enormous size, she was relatively agile and managed to dodge most of the spheres; as only the last one touched her right hand as it turned it to dust.
Realizing that she was no opponent for Rias, she decided to escape; in truth, she settled for escape moment Rias introduced herself, as fighting member of the Imperial House was plain suicide due to their Clan Traits and overwhelming power.
As she was running away, suddenly a white blur appeared before her, and with full strength, she punched her to her stomach, sending her flying several tens of meters and crashing into the wall.
As the dust settled, it revealed Shirone, armed with special gauntlets, who ended the escape of the criminal Viser. Shiro now looked different from her usual self, as she had more cat-like eyes, pair of cat ears, and two tails were waggling behind her.
Despite being only at the High-Class, her physical strength was at the pinnacle of the High-Class, and Viser was Ultimate-Class only in terms of Demonic Energy. Additionally, she was armed with a pair of gauntlets comparable to any legendary artifact in Earth myths.
At that exact moment, Rias cast a binding spell that bound Viser in her place where she crashed, not allowing her to move an inch.
"Any last words, traitor?"
Asked Rias rhetorically as she prepared Destruction Orb in her hand before shooting it at Viser, obliterating her from existence.
"Now we are done; the only thing remaining is to file a report for the Commissariat."
Said Rias as she looked around her.

MC POV
At the same time, on the roof of the opposite building.
I stood on the roof while watching the fight below me.
Even though it was between Ultimate-Class powerhouses, it was still entertaining. It appears that Rias had inherited from me, ending her opponents fastest as possible.
That was a good thing to have.
"Father."
Said a voice behind me as Vali landed down.
"So, what have you found out?"
I asked my adopted son/future son-in-law. I was happy that my daughter ended up with someone reliable and of noble blood, especially if that person was Vali.
"There are several Eight-Winged Ultimate-Class Fallen Angels and one Ten-Winged Cadre-Class Fallen Angel. The number of Low-Class to Middle-Class rogue exorcists is more than two hundred; other Fallen are numbering in tens. This is a clear trap for them and..."
He stopped in the middle of a sentence.
"Pinnacle Intermediate God was hiding near the base of Fallen."
He finished with a stern voice as I just nodded my head in understanding.
"Kokabiel, Melvazoa, Amaterasu... all of you are nothing more than just stepping stones in the path of mine and that of the Empire."
I said in a low voice.
"It appears that Susanoo cannot wait, and Kokabiel has joined hands with Melvazoa... losses that Evies have suffered in our hands forced them to search for allies here to at least hinder our progress. Fortunately, those Spirit Gods are too arrogant to do something like this. Still, it doesn't matter... Vali, go and capture that Intermediate God alive and give him to an Execution Temple for interrogation; I want to know what they are planning against us; if they realize our true goal, we need to move faster."
I ordered as Vali nodded and teleported away.
I looked at the people there.
"Ddraig, I hope we will meet soon."
I said as I teleported back to the Baator.
