Stepping out of the doorway, Noah found himself in the middle of a seemingly normal street.
The first thing he noticed was the suffocating feeling of repression surrounding him.
He felt he couldn't fully use his powers.
Specifically, the destructive side of his powers.
Focusing on his surroundings, Noah observed the street.
It was currently empty, devoid of any passersby, with only the occasional car passing by.
Quickly understanding the environment he was in, he used an illusion on himself to change his attire, causing his long black tunic to change into a black shirt and jeans.
He then looked around, seeing how there was a highscool to his right.
Glancing over the metal fence, he saw how the highschool courtyard was crowded with youngsters eating their lunch, chatting or doing whatever else.
With his extraordinary sight and hearing, he managed to discern the language they were speaking and the clothing of the people of this highschool.
After a moment, he understood where he was.
These people spoke Japanese and the attire these girls wore was a rather distinctive one.
"I never would have thought I would end up in this place..."
A wry smile appeared on Noah's face as he remembered the protagonist of this story.
He was currently in the world of Highschool DxD, specifically, he was at the outer gate of Kuoh Academy.
"I first devote to find out where I am in the story, at the same time I have to go missing as there are some existences roaming around here that could rival me.
The best thing to do would be to disappear for the time being."
Opening a portal, he teleported off into the distance and decided to wait to observe this guy first.
A few hours later, he watched as all the students finally emerged.
After looking around for a while, he saw a naive-looking brown-haired young man who had a perverted look in the depths of his eyes as he looked with a silly face at a black-haired, violet-eyed girl next to him.
The two looked like a couple in love as they walked out of highschool.
"Issei Kun! See you tomorrow! Don't miss the date!"
The girl waved goodbye as she gave an innocent smile to the goofy-faced guy across the road.
Issei could only nod as he was dancing with happiness inside.
It was the first time he got a girlfriend so it was quite normal for him to be so excited.
Noah saw this scene and shook his head slightly.
"It's a pity, I pray he never has a fate as bad as that of Wales the dragon, a legend among dragons whose name commanded respect, his reputation falls so low as to become known as Oppai Dragon.
Hahaha! I wonder what face he would make if he knew his own future fate."
Shaking his head, he decided to continue watching.
He didn't act since he knew there were already some eyes on Issei.
Besides he couldn't snatch his Sacred Gear from her as he didn't know the ritual to unlink them from their wearers.
Sacred Gears were extremely powerful weapons created by the god of the bible and given to humans so they could defend themselves from the other races that inhabited this world.
The next day, Issei went to the appointment with the girl named Yuuma.
Before Yuuma came, suddenly a girl with a strange cosplay approached Issei and gave him a pamphlet with a pentagram drawn on it before leaving.
Issei didn't think much of it and simply put it in his pocket.
They both went to the mall and stayed to do different activities until dusk.
As they passed near a store, someone bumped into Issei before quickly excusing himself.
Although a bit annoyed, when he saw the girl's bouncing breasts in front of him, Issei stopped thinking about that little incident.
But what he didn't notice was that the crumpled pamphlet he had tucked in his pocket had disappeared.
On the other hand, Noah looked at the small booklet in his hands before smiling slightly.
Then he simply crumpled it up and threw it in the trash can.
Who knew if that thing had a tracker or could be detected if it was destroyed.
It would be best to simply leave it tossed aside.
At dusk, Issei and Yuuma strolled through the park until they came in front of a small water fountain.
Yuuma walked away a little before turning around and with his usual sweet smile, asked Issei in a flirtatious manner.
"Issei kun, to celebrate our first date...would you do me a favor?"
"Eh?"
Issei got excited and began to fantasize.
"Could it be that he wants me to give him a kiss? Or could it be..."
"What's that about Yuuma-chan?"
With a goofy grin, Issei asked Yuuma, who had approached him.
"Could you...die for me?"
"Eh?
What do you mean...
Sorry Yuuma chan, could you say that again? I think I misheard you."
Yuuma leaned closer to her ear and said in a whisper.
"Please, would you die for me?"
Issei's face became more confused but he didn't have time to think when he saw Yuuma's clothes explode into pieces as he started to transform.
"I just saw them, they're so round!
It was only for a second but I could see them! They were her breasts!
My first glimpse of a pair of real breasts! And they're those of a very pretty girl!"
As Issei's mind wandered, Yuuma finished her transformation.
Her clothes became a sort of dominatrix outfit and a pair of black wings grew on her back.
"Wait! What the hell am I thinking about!? That's not the problem now.
She has wings?"
"I had quite a bit of fun with you.
Even though our time together was short.
To have a date with someone like you, a naive boy....
And this thing you gave me, I'll treasure it forever."
As he spoke, Yuuma stroked a bracelet in his hand.
Conjuring a spear made of red light, Yuuma smiled fiercely as he directed the spear towards Issei's chest.
"Die for me...huh?"
Suddenly, Yuuma couldn't move a single muscle.
A terrifying gravitational field pushed her down, forcing her to her knees.
Issei was not unharmed either as he slammed to the ground unable to move a single muscle.
A hand landed on each of them before they disappeared from the scene.
A few seconds later, a short white-haired girl appeared and started sniffing around the place.
"The traces have been erased..."
Noah appeared in an abandoned house on the outskirts of the city while still having the two of them wrapped in his willpower field.
He first absorbed Yuuma's soul so he could read his memories.
As a two-winged fallen angel, the lowest of the hierarchy, Yuuma could barely be considered rank 3.
With her willpower power of maximum rank 6, Noah could easily suppress her.
As for Issei, Noah simply knocked him out.
Reviewing the information in his mind, he quickly understood how the Sacred Gear extraction ritual worked.
Suddenly, Noah felt an extremely subtle aura approaching from afar.
With a smile, he stuffed Yuuma's dead body into his magic gourd before grabbing Issei and teleporting away.
He didn't stop opening portals until he got close to the sea.
Then he simply took out his hovercraft and with a magical barrier covering it, he dove into the sea, leaving Japan completely.
A few hours later, he appeared on a beach in the Caribbean.
In this place it would be impossible for them to track him.
Taking advantage of the fact that it was nighttime, he flew to a half-destroyed shack and with earth magic, created a huge stone cross before beginning to carve complicated runes into its surface.
The ritual was basically about destroying the link between the Sacred Gear and its wearer but since the soul of the red dragon, Ddraig, resided in this Sacred Gear, destroying the link would be complicated as the dragon would sense it and fight back.
So Noah tried a more direct approach.
He simply placed Issei on the cross, which took care of momentarily isolating the Sacred Geass, before simply destroying Issei's entire soul and connecting that link to his own soul.
He could do this without alarming the soul of the Welsh dragon because it was currently asleep and because he did not touch the link.
Suddenly, Issei's left hand glowed with a green light before a green orb shot out towards Noah's left hand.
At the same time, the sleeping soul inside the orb began to awaken.
Noah quickly teleported back to Japan as the ruined hut exploded into pieces.
Ddraig awoke and uttered no words to alert his new host.
Instead, he scanned Noah's body using his senses.
Noah sensed him and smiled.
"So you woke up huh..."
"You... Can you feel it? And what about this body? You don't seem to be either human or belonging to the other races. What are you?
I sense a demonic aura about you but I also sense other distinct auras."
"Don't you think we should introduce ourselves first? Ddraig?"
...
"If you know who I am what kind of additional introduction do you want?"
"I don't know. You should at least say hello instead of scanning your host's body so rudely. Now I feel like a young girl whose panties have been seen."
"..."
"..."
"..."
"You're a tough crowd, well whatever! My name is not important, but if you want you can refer to me as Noah, that's my name."
"Whatever, I'll go back to sleep."
"..."
"..."
"..."
"Are you still there?"
...
Noah was speechless.
"It's Tiamat!"
"Where?!"
Ddraig's heart jumped for a moment as he remembered a certain angry dragon queen.
"A no, I just imagined it."
"Brat..."
"Haha! It was a joke, a joke. But you should have fixed that problem long ago, now that I'm your new host that broad will come after me sooner or later."
Ddraig decided not to respond to Noah's teasing and simply fell asleep while remembering that battle.
A long time ago, when he was going to fight his arch rival, Albion, he borrowed some little things from the dragon queen Tiamat.
But who would have thought that right at that moment war would break out between angels, demons and fallen angels?
And what's worse, the leaders of the three factions interrupted their fight against Albion.
As a result, the two heavenly dragons, who were only surpassed by the dragon gods, became enraged and directly confronted those three annoying guys.
As a result, both he and Albion lost their bodies and their souls were sealed in Sacred Gears.
As for the weapons he borrowed from Tiamat, they were stolen by humans passing by after the battle.
Now that mad queen would attack any of her hosts as revenge.
Noah wasn't really that worried about Tiamat, at worst he could run away.
The next day, Kuoh Academy announced a change of teacher for the high school 2-B class.
The previous teacher, due to some complications, had to move to a distant city.
Today, Noah walked into his new class dressed as a teacher, with gold-rimmed glasses on the bridge of his nose and his white hair pulled back in a ponytail with two locks falling on either side of his face.
Due to drinking the anti-aging potion in his twenties, his appearance was always stuck at that age so he looked only a few years older than these 17 and 18 year olds.
Because this was formerly an all-girls school and it wasn't until recently that it became a co-ed school, the majority of students in this class were girls.
Noah could feel the piercing, lustful gaze of some of the girls present.
Due to his incessant cultivation and above all due to his demon god blood, his features were becoming more and more accentuated and enhanced, added to the fact that he looked like the typical handsome older brother, he proved to be a fatal attraction for these young girls full of love fantasies in their heads.
Noah heard a sneer from Ddraig in his mind but just secretly rolled his eyes.
This guy wanted an orgy set up in the middle of class, which left him speechless.
"Now I understand why this guy was such a match for Issei, turns out they're carved from the same mold."
Shaking his head inwardly, he clapped his hands once to get the attention of the young men in front of him before he began to introduce himself.
"Good morning everyone, I am your new English teacher, Noah Astaros.
Due to some setbacks, your previous teacher will no longer be able to continue teaching you so we will be in each other's care for the remainder of the semester.
Nice to meet you all."
Noah wrote his name on the board before wiping it off again and sitting back in his chair.
He then asked the students to stand up one by one and call out their names aloud to memorize them before class began.
The one he especially noticed was Rias Gremory's servant, Yuuto Kiba.
He also noticed Issei's two friends, Matsuda and Motohana, but only shot them a light glance before returning his focus to the class.
When the hour was over, the students said their goodbyes and there were even some bold girls who gave him love letters or some fruits, which he ate without thinking.
As for the letters, he simply stuffed them in a drawer.
As he left the classroom, he passed a red-haired girl whose breasts jiggled strangely with every step he took.
She was abnormally mesmerizing but with his willpower, he couldn't be affected by something as simple as the seductive charms released by a demon.
The girl who walked past him was none other than the female lead, Rias Gremory.
The two made light eye contact before looking away.
"Boy, you look like you stepped into a nest full of predators."
"Haha, just wait and see who's the real prey here."
With a mysterious smile that made Ddraig want to smack him, Noah walked off to the dining room to grab a coffee.
