Omniversal Travel

Raiser, who was already filled with rage, attacked as soon as the alarm sounded.

Noah's left arm lit up with a green light before the Boosted Gear appeared.

"Boost!"

With a flash of green light, the Boosted Gear doubled Noah's physical strength and mana.

Despite having a wealth of powers, Noah decided to hide his other powers, passing him off as a human mage with a strong body.

Though logically, Ddraig already knew of some of his hidden abilities since it resided in his body.

With a smooth spin, Noah threw a punch at Raiser that slammed him straight into the ground before launching a concentrated energy bolt that pierced his chest.

Raizer's pierced chest burst into flame before it began to regenerate as he staggered to his feet.

"Boost!"

Before he could recover, a punch broke his nose and sent him flying a hundred yards away, crashing into the coliseum wall.

An explosion of angry flames erupted from where Raiser crashed before shooting out towards Noah.

"Boost!"

Noah grinned before clenching his fist.

A red aura surrounded his fist before turning into a crimson comet that shot out towards Raizer.

"Galaxy Impact!"

With a bang, Raizer flew off while Noah hovered in midair.

"Interesting..."

Sirzechs Lucifer, Rias' brother and the current head of the Gremory clan and one of the four demon kings, watched the fight with obvious interest in his eyes.

On one side of the bleachers, Rias sat with his servants and on the other side sat some of the members of the Phoenix clan.

Among them, a group led by a bespectacled girl was attentively watching the battle.

They were the representatives of the Sitri clan, another demon clan and they would be responsible for acting as referees in this battle between the Gremory clan and the Phoenix clan.

At the same time, this battle was being broadcast to the entire city of Gremory.

Raiser stood up again before turning into a fire phoenix and charging at Noah again.

"Balance Breaker!"

With a flash of green light, red armor covered Noah's entire body and a long pointed tail shot out from his back.

"Boosted Gear: Scale Mail!"

With a sonic blast, he launched himself at his opponent.

Rias tightened his grip on his chair and stared at the battle.

Continuous notification sounds rang nonstop in Noah's mind.

"Boost! Boost! Boost! Boost!..."

His strength was doubling with each passing second.

"Haha! I'm getting more and more excited!"

With an opponent that looked like a punching bag that he could punch continuously, Noah got excited and started punching more and more wildly.

A pair of draconic wings appeared on his back as his speed doubled.

With his enhanced speed, he began to play with Raiser as if he were a ping pong ball, tossing him back and forth.

Unnoticed by anyone, Noah hid among these blows a tracking spell that he placed on Raiser's back.

A minute later, the Boosted Gear's warning sounded.

"Reset!"

All the armor Noah was wearing was removed and even the red gauntlet was removed.

Noah's body had reached its power-up limit and he could no longer increase it any further.

His power multiplied an exaggerated amount of times, taking his physical strength from rank 4 to rank 6, which was truly insane.

But his body could only be strengthened to such a level and he could only withstand such an amount of increase for one minute.

If he used his amalgamation transformation along with his demonic transformation, he could increase the time and strengthening limits but doing so would be foolish.

Revealing his cards just to win this duel would be too stupid.

Looking down at Raiser, who was lying on the ground, limp and with barely a few embers burning on his body, Noah turned around and jumped into the stands next to Rias' group.

"Onii-Sama!"

A young blonde girl jumped down from the bleachers and ran over to check on Raiser's condition.

Raiser looked devastated, his eyes staring into nothingness, as if his soul had left him.

Although his body was recovering, his mind was broken during the battle and it would be very difficult for him to recover.

The beating Noah gave him along with the humiliation it caused him completely broke his mind.

This was within Noah's plans, he wanted Raiser to be in this state on purpose because he would need him in his future plans.

"Ara ara, looks like your problem has been solved, president."

Akeno to the side covered her mouth and smiled at Rias, who looked at Noah next to them and then looked at Raiser on the ground.

Originally she wasn't so sure about trusting this mysterious professor who appeared out of nowhere but after he showed her the Boosted Gear, whose owner had mysteriously disappeared a few days ago, she was a bit convinced, especially after Noah defeated all of his servants in a mock battle where he beat them with pure martial skill without even using his Boosted Gear.

"Young human wielder of the Boosted Gear, as a reward for your victory, I can offer you whatever you want, wealth, status, knowledge.

But my dear sister is not included in that list."

Sirzechs Lucifer approached Noah with a friendly smile and explained.

"I cannot allow my sister to marry a human. After all, the number of pure-blooded demons only decreases every year and..."

"I understand."

Noah directly interrupted him.

"After all, this has been nothing more than an agreement between Miss Gremory and I right?"

Noah smiled at Rias before turning to look at Sirzechs and begin negotiating on what he could offer him.

Rias squeezed her skirt tightly as she thought to herself.

"This bastard, he took my first kiss and says it was just a deal so easily."

"Ara ara, how heartless of you, professor."

Noah simply ignored Akeno who wanted to add fuel to the fire and kept asking Sirzechs about the different things he could get.

In the end Sirzechs allowed him to enter his library once and stay inside for a day.

Noah smiled secretly as with his Omega chip, he could simply scan the contents of the books and scrolls once and they would be stored in his database forever.

The next day, he scanned all the books in Sirzechs personal library before returning to the human world and going about his routine as a teacher.

As for why he helped Rias get out of her marriage contract, it was to get closer to her since she was after all the female lead.

Aside from placing the tracking mark on Raiser.

"I refuse! I will not allow you to use Akeno's body for your investigations!"

Rias seemed in a bad mood and refused Noah's requests directly without even listening to everything he had to say.

Noah simply ignored his words and spoke to Akeno directly.

"Akeno, the truth is that it will be quite simple, just let a machine scan your body and a drop of your blood and that's it."

As he spoke, Noah rubbed the space ring on his hand and a capsule came out from inside.

"All you have to do is get undressed and lie there and after five minutes, the scan will be over."

"Didn't you hear me?"

Rias looked visibly upset, especially when she heard that Akeno had to undress.

"Sigh, women are so complicated."

While shaking his head, Noah took a cookie from the bag of cookies Koneko was eating from, who looked at him as if he was a criminal who had stolen her most precious commodity.

As he was about to take another, Koneko pulled away and sat down on the other side of the couch.

"By the way, Yuuto, is it okay with you if we train swordsmanship later?"

"Astaros San is a swordsman?"

Yuuto was surprised because Noah didn't have any sword with him and in the previous confrontation against Raiser he didn't use a sword.

"Well, when I reached a certain level ordinary swords were no longer useful to me so I had to focus on martial arts until I find a good weapon, so my swordsmanship skills are somewhat rusty."

"It's okay, we can go to the training ground later."

While they were talking, Akeno had taken off his clothes and was about to enter the capsule.

"Akeno..."

"It's okay president, after all, the professor is our ally and wouldn't harm us without reason.

Right professor?"

"No doubt."

Noah gave Akeno a thumbs up before going back to try to grab one of Koneko's cookies but what he received was a crashed foot in his face.

"They're mine."

Koneko hugged the bag of cookies before switching couches directly.

"Beep!"

"Scan completed!"

"Collecting a gene sample."

A thin needle jabbed into Akeno's finger before drawing a blood sample and storing it in a tube.

Akeno stepped out of the capsule and put his clothes back on, unconcerned by the presence of the two men in the room.

Noah put the capsule away again before nodding to Yuuto to leave.

The two arrived at the Kendo training ground and grabbed wooden swords.

Yuuto grabbed a straight sword while Noah grabbed a wooden katana in his left hand and a straight sword in his right before taking a defensive stance.

The confrontation between the two lasted half an hour and they didn't finish fighting until Yuuto's sword broke in half.

"You are talented. Your swordsmanship skills are mastered almost to perfection but you need a style of your own, you should focus on that aspect.

If you want we can have regular sparring from time to time, you can only improve your skills if you have a suitable opponent."

Putting his swords aside, Noah helped Yuuto up while giving him some advice.

To improve in his swordsmanship, one had to develop one's own swordsmanship style and master it completely.

Although one could learn a style that belonged to someone else, in the end it would not be one's own style and would end up stagnating without ever reaching the level of the original creator.

One could learn other styles to use as a reference to perfect one's own, but focusing on mastering those styles would be the easiest and at the same time the stupidest thing to do.

The phase Noah was in at the moment was to discover and develop his own fencing style, which was the double blade style, with a curved blade in his left hand and a straight blade in his right hand.

The next day, Noah returned to his daily routine, teaching in classroom 2-B.

As usual, Issei's two kinky friends were still going about their perversions although they were noticeably a bit subdued due to the disappearance of their third member of the kinky trio.

On the other hand, Asia, who studied in the same class, kept attracting attention and all the girls gathered around her like flies.

Especially when they found out her current identity, that she was the teacher's little sister.

The girls kept pestering her to get a date with Noah.

In the evening, Noah went to the abandoned church on top of the mountain, where originally Asia would be taken by the fallen angel who was going to kill Issei in order to take away Asia's Sacred Gear.

He set up a hidden sealing array and an alarm array before retreating.

A couple of days later, in the middle of the night, two hooded people entered the abandoned church before removing their hoods, revealing their appearances.

They were two young girls of about 18 years old.

Just as they stood in the center of the matrix and were about to speak, the sealing matrix activated and black chains came out of the ground before wrapping tightly around them.

A person materialized behind them and grabbed the swords on their backs before smiling mysteriously at them.

They could not see the other party's face due to the hood he wore and only saw his sly smile and his two wings filled with black feathers before he disappeared.

The chains that restrained them also disappeared but they could no longer do anything, their sacred weapons were gone.

At the same time, Noah materialized in an alley, where he encountered a silver-haired boy with red eyes.

This was the renegade exorcist who was standing next to Asia.

Noah left him alive because this guy allied himself with one of the big shots of the fallen angels, who handed him three sacred swords.

Noah took the weapons before his head exploded, then reappeared in his room and threw the five swords on the bed.

He first looked at the two swords he snatched from the two girls.

"Destruction Excalibur and Mimic Excalibur."

Then he looked at the other three swords.

"Rapidly Excalibur, Nightmare Excalibur and Transparency Excalibur."

"Oh... Interesting toy you got there boy.

But how did you get five of the seven Excalibur shards?"

Excalibur, the legendary sword of King Arthur, broke at some point in history into seven fragments that became seven different swords.

Today, Noah had obtained five of the seven shards in one fell swoop.

Kokabiel, a 10-winged fallen angel and one of the leaders of the fallen angels, stole three of the Excaliburs and handed them to the renegade exorcist.

"But boy, you can't use them without holy energy, which makes them just useless trinkets for you don't it? Then why do you want them?"

"Maybe not now but in the future they will be of great use."

With a mysterious smile, Noah stowed the Excaliburs in his magic gourd.
