The name Ars Nova became famous in just one night

Seeing Rias and Sona insisting on fighting him, Akira decided to show his full strength.

"Your unyielding attitude is commendable, but... Not knowing the difference between your strength and that of the enemy's is pure stupidity. In life, there is no such thing as a winner forever, and no loser forever."

"The winner is the one who manages to survive, don't waste your chance… Let me show you the difference in true strength between us, I hope you won't be so stubborn next time."

Akira ignored Rias and Sona, who were confused by his philosophical advice, and with the absolute control [Explosive Power] gave him, he used [Gift: Last Future Embryo]'s full power!

Akira's right hand was enveloped in Aurora's light. With the appearance of an aurora in his right hand, which could obliterate the stars in the night sky, it turned into a huge pillar rising up into the sky.

The appearance of the pillar caused the night sky in Japan to instantly become day and even the earth trembled as if unable to withstand a power of this level.

Witnessing this scene, Rias and Sona stared wide-eyed, the two closest to the source of the aurora. The ones who sensed how frightening this aurora's power was were both of them.

With Akira as the center, the earth and atmosphere rumbled loudly.

All the supernatural beings, be it Devils, Angels, Fallen Angels, Gods, Youkai, Vampires, Dragons, etc., they looked up to see the aurora pillars rising through the sky.

Either weak supernatural beings or strong supernatural beings like the Top 10 Most Powerful Beings In The World. In the face of the aurora pillar, they all felt the same thing, namely, death.

...

In India, Hindu mythology.

"Who has that power of destruction?! It is much stronger than the power I have?"

Shiva, God of Destruction, and also one of the Top 10 Most Powerful Beings In The World. He was stunned to witness that aurora pillar, and he dared not guarantee that he would live if he received that attack.

Next to Shiva, one of the Top 10 Most Powerful Beings In The World appears, he is Indra, the King of Heaven and Gods.

"I don't recognize that possessor's energy… Who exactly is that person? There's no way such a strong person isn't in the Top 10 Most Powerful Beings In The World." Indra mumbled confusedly.

"Are you able to stop the attack, Indra?" Asked Shiva without taking his eyes off the aurora pillar.

"Don't joke, Shiva. If you who are stronger than me, can't stop that aurora pillar, how can I?" Indra smiled wryly while shaking his head.

...

In the Underworld, the territory of the Gremory House.

Sirzechs sensed a terrifying aura from the human world, so he tried to teleport to Kuoh Town out of concern for his little sister. But space is distorted, and unstable, which makes teleporting impossible.

"Grayfia, do you know something?" Sirzechs asked his wife who was wearing a maid's uniform.

"Sirzechs-sama, this aura is from Kuoh Academy, it is likely that Rias-sama provoked a certain powerful existence."

Grayfia was monitoring Rias with her ranged magic, and she also confronted it. She was prepared to come anytime to help Rias, if the other party tried to kill Rias and Sona. But an unexpected situation occurred, his long-range magic was shattered by the aurora pillar that appeared in the other party's hand.

What surprised Grayfia the most was that she could no longer spy with her magic due to the energy surge of the aurora pillar destroying all magic on earth.

"What! I have to save Rias as soon as possible!"

Hearing that this matter was related to his little sister, Sirzechs tried to forcibly teleport. As a result, he appeared in another city in the Underworld.

Sirzechs panicked even more, he was worried that his little sister would have an accident. He kept using various methods to get to the human world, and the result was failure.

"Perhaps Ajuka has a method for this situation."

After repeated failures, Sirzechs went to the territory of the Astaroth House.

...

Not only was the supernatural side panicked, but the ordinary human side wasn't much more panicked.

Witnessing the phenomenon of night turning to day, people in Kuoh Town could only pray, run away, engage in anarchy, and take other actions.

Fear is born from a lack of knowledge, people are afraid of something they don't understand.

That is what is happening to the supernatural side and the human side today.

...

On the roof of Kuoh Academy.

Rias, Sona, Akeno and the others had long fallen to the floor, their bodies shaking and shivering. In the face of a power capable of annihilating the stars in the sky, their resistance was small and insignificant.

(This is my first time using the [Aurora Pillar], it's much stronger than expected...)

With the absolute control that Akira had, he only demonstrated the [Aurora Pillar] to the world, and he was sure that the Top 10 Most Powerful Beings In The World sensed the [Aurora Pillar].

Akira even noticed the great fluctuations of space, he was sure that if the [Aurora Pillar] didn't annihilate the magic on earth right now, the Top 10 Most Powerful Beings In The World would instantly teleport here, especially Great Red and Ophis.

(Am I overdoing it?)

Akira glanced at the pale faces of the girls in front of him, the worst situation was Sona's servants, some of them wet their pants.

(I think that's enough)

Clenching his fist, Akira deactivated the [Aurora Pillar] in his right hand.

The sky restored the darkness of the night, but the people in Japan were still panicking.

"Now you understand the difference between me and you guys, right?" Akira said in a deep voice.

Rias and Sona nodded, and thoughts of fighting the person in front of them vanished. They now felt ridiculous wanting to catch this person.

"That's good, I'm thirsty to go soon, this place will be crowded soon. Adios!"

After saying goodbye in Spanish, Akira's figure disappeared.

"Phew~..."

Only after 5 minutes of Akira leaving did Rias and Sona relax.

"That person is so scary… I don't want to meet him again."

Sona pushed the glasses on the bridge of her nose with trembling hands.

"Ars Nova... Maybe Onii-sama knows about him." Rias looked down at her palms which were still trembling.

"Rias."

"Sona-chan."

Not long after, red, green and blue magic circles appeared on the floor.

The ones who came were Sirzechs, Ajuka and Serafall.

"Thank goodness you guys are okay."

Sirzechs' tense mind was relieved to see Rias in good condition, even though his face was deathly pale.

"Sona-chan! Onee-chan is worried about you!"

Serafall took Sona in her arms.

If it was normally, Sona would have rejected her big sister's intimate act. But not this time, she felt slightly safe in his big sister's arms.

"Oh, it turns out we were preceded."

"It can't be helped, the distance between India and Japan is quite far."

The ones who spoke were Shiva and Indra.

Sirzechs and Ajuka welcomed the arrival of the two Hindu mythological gods. After all, they are part of the Top 10 Most Powerful Beings In The World.

"So, what exactly happened here? Who was the person that caused the aurora pillar just now?"

Shiva didn't beat around the bush, and asked directly.

Sona had recovered a bit of composure and said:

"It was caused by someone named Ars Nova."

"Ars Nova?" Shiva looked at Indra.

Indra shook his head, indicating he didn't know.

"This is the first time I've heard this name." Sirzechs held his chin and thought.

"I also do not know." Ajuka said seriously.

Then many representatives of supernatural beings from various factions came to Kuoh Academy to inquire about the situation.

Like Azazel from the Fallen Angels faction, Michael from the Angels faction, Odin from the Norse faction, Yasaka from the Youkai faction, each family head from the Five Principal Clans, and the other factions.

Seeing more and more situation representatives arrive, Sirzechs asked Sona to prepare an auditorium to use as a meeting room.

That night, the representatives of the supernatural faction overheard Rias and Sona's explanation regarding the individual named Ars Nova.

The appearance of Ars Nova had caused an uproar among the leaders of various supernatural factions.

It's a shame that Ars Nova's identity remains a mystery, other than his male gender, all of his information is still unknown.

Even the gods and goddesses, who specialized in divination, couldn't find out anything about Ars Nova.
