Disclaimer: Don't own both Highschool Dxd and The Elder Scroll V: Skyrim

Everywhere I search it always the same Alduin will be turn into a human (so far the fanfic that I have read at least) so this time Alduin will be staying as a Dovah/Dragon and all the Dragon language/Dovahzul I use in this story is translated using [ www . thuum . org [/] translate . php] (remove the spacing and '[ ]')

Just to clarify thing, this is not a response toward the High School DxD and Skyrim crossover challenge by Julbot1. This is purely my own story BUT I do admit that I use Julbot1 idea and I have ask for his permission to use it.

{Void}

"Dur tol Dovahkiin ahrk Paarthurnax." The now defeated Alduin said as he flies around in the void after the last Dragonborn kill him in Sovngarde.

"Zu'u los Alduin faal Lein Naakin ahrk Zu'u fen kos rigir fah dii nahkriin." He growled, vowing to get his revenge and return back to the world to destroy it as it was prophesied in the Elder Scroll.

For Alduin the strongest Dovah to be defeated by a mere joor is humiliating and even his comrade his on fron Odahviing has betrayed him just like his former second in command Paarthurnax who teaches the joor how to use Thu'um and defeat him for the first time.

"Fod Zu'u ofaal tir do het, hi fen kos dii diist niraat Dovahkiin, Zu'u fen luv hi wah malur voth dii jot ahrk du hin sil ko Sovngarde." he said as he fly aimlessly in the vast void.

It seem it has been several minutes has past as Alduin fly to search for the exits and the way to return to Mundus he finally find the way, right in front of him he could see it clearly as the shinning portal that will bring him to Mundus or at least Sovngarde.

With a smile on his draconic face; as close as it is to smile allowed by his face that is, he begin to fly toward the light faster than he fly before.

"Zu'u fen daal ahrk lost dii nahkriin!" He roared.

But it seem fate is not on his side because just several miles before reaching the portal a bright light that is so bright it illuminate the whole void.

"That is enough my son." a voice come from the blinding light.

Alduin recognizing the voice as his father voice stop and watch as the light begin to take form and begin to lose it intensity. When the light died down Alduin can see his father form, the of a massive slivery white Dovah.

"Fahvos vuth zey nol dii dez Bormah?" Alduin asked his father

"I'm not stopping you from fulfilling your destiny Alduin; no you are destined to destroy the world but not now, you have ignored my order and begin to enslave the men and mer alike." Akatosh said.

"Fahvos los nii folaas Bormah, mu dovah los avokei wah muz ahrk fahliil medaas ful nii los gahziinuv fah ont uth niin." Alduin stated, defending his action in the past

"One day Alduin you will know your mistake. But for now you must not go back because the time for the world destruction is yet to come so for now I will send you away to another world and cut your connection to this world temporarily" Akatosh said to the stunned Alduin

"Fos! Fahvos fund hi dreh daar Bormah?!" The stunned Alduin said at his father

"I do this so that you may understand the concept of mercy, humble and kindness Alduin. You may be the harbinger of the end but even you must feel this emotion so you may become more than just the symbol of destruction" said Akatosh

Alduin hearing this was speechless as he never would have thought that he would be punished because of his past deed as the Aedra rarely bother with mortals' affair.

"As such in this other world you will be sealed inside a young boy who will live a harsh life ahead of him because of something that out of his control and I want you Alduin to guide him and be a role model for him. Now go Alduin and make me proud" was Akatosh final word to Alduin as he open up a portal that lead to the new world and push Alduin through it.

"Nid! hi nis dreh daar wah zey Bormah!" shouted Alduin as he is transported to his new position in the new world, a world where the strongest existence is a dragon, a world where his power and Thu'um will be revered as the strongest power, a world of supernatural.


{High school DxD World}

The world where the supernatural exist but in secret, a place where the angels, devils, fallen angels, youkai, Valkyrie and any other supernatural being that people can think of they all exist here.

It was night time in the country of Japan when there in the sky if one were to look at it they would surely find a portal of some sort open up and a purple/black colored orb can see exiting the portal. For several second the orb stay still as the portal behind it close.

After the portal fully closed the orb suddenly move at a high speed going through the sky as it search for its target, a young boy whose life will change tonight as he is exposed to the world of supernatural at a steep prices.

{In a wood of a camping location}

Issei Hyoudou a 7 years old boy he is the only child of the Hyoudou household ad today is a day where they will be camping at the famous camping spot near their town Kuoh. It was a day that young Issei look forward to as his father rarely home and always away because of his job, but recently his father manage to take a leave from work to spend the time with him.

All seem to be fine as he picked a spot where they will be staying for the whole day because it was not a holiday the place that they went to is quite really quite as there is no one else there except them.

The day seem to be perfect to little Issei as he play all day with his father and do all sort of things together with his parents but unfortunately for him the night will be the night that will change him for the days to come.

That night a group of people come to him and his family the group consist of four people or what would be people if not for the fact that they have wings growing from behind them the leader of the group it seem has at least two set of raven wings with the others having only one set.

Now little Issei is terrified because as soon as they come they immediately begin to hurt his parents. They begin to beat his father and mother even him.

As they beat them, his mother and father use their own body to protect him. The group it seem to be looking for something as they keep on saying things like "Where is the Sacred Gear" or "Give it to us."

The beating continue for several minutes before the leader asked for his father to be brought to him.

"Now let see if you have the Sacred Gear we are looking for" he said to Mr. Hyoudou as he was dragged to him by his subordinate.

"P… please spare us w… we don't know a… anything about this S… Sacred Gear thing you're l… looking for." Mr. Hyoudou sputtered through the pain he is currently in.

"Heheh… we will see about that human." he said as he use some sort of devise and point it at Mr. Hyoudou. The devise that look like a futuristic gun with a screen attached to it begin to produce blue light and begin to scan Mr. Hyoudou.

*Tiiiiiiiiddd* the devise signalled the wielder after the scan is complete.

"Hoho it seem you're right you don't have it." the leader said.

"S… so can y… you please let u… us go now" plead Mr. Hyoudou.

"No." the leader simply said as he produce a red light spear and plunge it through Mr. Hyoudou heart.

"Tou-san!/Nooo!" Screamed a terrified Issei and his mother as they watch the winged man kill their father/husband.

"Remy bring me the woman!" said the leader to the only female member of the group.

"No not my kaa-san!" Issei yelled as he tries to fight the evil winged lady from taking his mother.

"Please spare us!" His mother cried as she struggle to get out of the woman grasp

"Just move it you b****!" Remy growled, "Come on move it!" she added as she roughly pulling Mrs. Hyoudou by her hair

Seeing his mother struggle and the pain of losing his father somehow manage to awaken something inside of him

"Leave my kaa-san alone!" He said suddenly as his voice sounded much softer and almost melodious than before even though he is screaming

But the weirdest thing is that the woman Remy suddenly stopped moving and release his mother as her eyes is lost it colour and change from purple to grey. Mrs. Hyoudou seeing the chance to escape run toward her child in order to run away together.

But she is captured again by the other man while the other just backhanded Issei sending him flying against a tree behind him with a small thud signifying the small force that the man that was not enough to badly injured him.

"What the hell Remy! What are you doing!" The one asked who recapture Mrs. Hyoudou who cried and plead is ignored.

"So the boy is the one who possess the Sacred Gear" The leader said as he walk toward Remy along with the other who backhanded Issei into a tree.

"So he can command anyone to obey him?" ask one of his subordinate.

"No, I know that Sacred Gear it is called [Charm Speak] and it only worked on the opposite sex of the user and only work once per person only." The leader said as he brought his female subordinate out of the SG power.

"Wha..! What happened to me!" The now dazed Remy asked.

The leader begins to tell Remy what happen to her. When all of this going on no one notice a purple/black orb going inside the downed Issei changing something deep inside of him.


{Inside Issei SG}

"Fos los daar staad?" Alduin asked to no one but himself as he find himself in what appear to be some sort of a room with several chain wrapped around his legs, wings, tail and neck connected to the wall of this room with a screen of some sort showing a blurry scene in front of him and what sound like people talking.

"Now you are inside the boy I mentioned. His name is Issei Hyoudou and as incentive to help him Alduin you should know that if the boy dies so will you with no chance of ever coming back" echoed Akatosh voice around him.

As for Alduin he could only growl as the chains begin to absorb his essence and knowledge about Thu'um from him and giving it to the boy.

{Back outside}

Issei still hurt and a little disoriented from his crash with the tree behind him stand up and watch what happen in front of him as he see that the lady named Remy is now holding his mother by her hair using her left hand while her right hand is holding a green light dagger.

"So you think you can control me huh! Well say goodbye to your mommy kid!" She said as the other male laugh it up as if it was a joke.

"I love you Issei, always." Was his mother final word before Remy slit her throat open in front of Issei as he watch his mother died in front of him as she smile at him for the last time forever as the winged people laugh at his lost.

"Why?" Issei asked, who was incredibly speak with a calm voice which if they noticed is quite creepy for a 7 years old to have in this situation.

"Why? Well it easy because we are the Fallen Angels and you, you are just a human an inferior being compared to us" The leader said with a smug face as he and the other Fallen Angels laugh more.

"Kaa-san, Tou-san… you kill them… you kill my parents…." Issei said in a low voice.

"So what of it boy what will you do? You are nothing against us." Remy said.

"I... I will kill all of you!" Issei said as his voice sounded different at the end as he held up his head to meet the eyes of his family killer and they were surprised to see that Issei original brown eyes is no more now in its place is a demonic looking eyes; his irises are now bright orange in colour with black slitted pupil while his sclera turn from white to black.

The fallen angels is so shocked at the turn of event freeze in their spot because of the glare directed at them from a 7 years old boy.


{Alduin}

"Geh sen brah dii suleyk ahrk al niin fah nust krilon wah kopiraan niist superiority ko teyn do zey" Alduin grunted as he encourage Issei to use his Thu'um to destroy this so called fallen angels who dare claim to be superior than the boy and by extension him.

{Issei}

As for Issei in his rage he began to hear a voice inside his mind.

'Kill them boy, gevahzen wah zey prove to me that you are worthy to use my Thu'um and meyz dovah become a dragon! Saag nii sen said it boy zaan nii tir shout it out…' voice inside his head said as he suddenly has an urge to say a sentence.

A sentence that he doesn't know how he know it but in the mean time it was as if he know it since the beginning; hell he never heard this language before but still the urge to say it is so strong that he end up shouting it just as the voice demand him to do.

"Yol Toor Shul!" Issei shouted.

And just like that the effect is astounding to say if there were people watching they can see that fire literally begin to escape little Issei mouth as if he is a dragon breathing fire upon his prey and just like that in the instant the fallen angels knew no more.

The last thing that they experienced before their death is the foreign sentence and that the world tremble as the world left the boy mouth.

The forest burn to the ground as little Issei stands in the center of it, the fire stay away from him and his parents' corpse as if they were afraid of the boy wrath.

Because of the sheer anguish that he suffers he released all of his suffering in one final roar that shakes the Heaven, Underworld and Human world. The roar of a suffering soul, the roar of an anguish boy, the roar of mortal and most importantly the roar of a Dovah!.


{Dimensional Gap}

A large red dragon can be seen in the dimensional gap fly around endlessly and aimlessly before it suddenly stop as it could feel the dimensional gap shake violently and a roar, a very primal roar backed with power that is even more powerful than its own can be heard.

And for the first time in history the strongest existence The Apocalypse Dragon, The Dragon of Dragons, The Red God-Emperor Dragon, True Dragon Great Red felt the feeling of fear because of the roar.


{Heaven}

A beautiful place with people wearing white cloth with pure white wings and a halo above their head. All of them is minding their own business when suddenly the whole Heaven trembled and a mighty roar is heard; immediately all of them immediately scramble some to find their leader for information about the roar and some to find a hiding place fearing the being that could be behind those roar.

In a throne room a youth with long blonde hair, green eyes, wearing golden armor-like clothing with twelve golden wings on his back and a golden halo above him stood from his throne along with a gorgeous woman with a curve and figure women will kill to get. She also have long blonde hair with a curly style that frame her beautiful face with green eyes, she like the male beside her also have twelve white wings behind her and a white halo, to complete her look she also wear an all-white dress that did nothing to hide her voluptuous figure.

"What was that brother Michael?" she ask her now named brother with the look of nervousness on her beautiful face.

"I do not know my dear sister, but whatever it was Gabriel it is stronger than father" Michael replied with the look of concern on his face as he certainly feel the power behind those roar and he regret to say it but it was even more powerful than that of his father when he was still alive.


{Underworld}

Inside a castle in the devil's territory a handsome man with long crimson hair, a pair of blue-green eyes and wears armor that covers his chest and shoulder area along with a cape. The armor is gray in colour with orange lining with the cape being navy blue on the outside and red on the inside.

Said man is now having his check pull by a beautiful silver haired woman, with equally beautiful silver colored eyes and wear what appear to be blue and white French maid outfit with long sleeves and a white maid headband over her head, with red lipstick as a cosmetic accessory.

"Ooohh… come on Grayfia-chan it is still early for me to do this sort of things" He said with tears coming out of his eyes out of pain while said woman just ignore his plea.

"No Sirzech-sama, as a Lucifer it is your job to do this 'sort of things' as you said it." She said not releasing her hold.

"But Gra…" whatever it was that this Sirzechs was about to say, he can't continue it as suddenly the whole castle; no the whole Underworld tremble with the echoes of a powerful roar that pack enough power behind it that he can feel it, as if the source of the roar was right next to him.

No longer than 15 minutes after the roar his door burst open and he can see his friends and the other Maou of the of the Devils come through it and even the laziest Devil Falbium Asmodeus is now fully awake and have a serious face along with the others.

"Yes I also feel it" said the now serious looking Sirzechs answering the unspoken question of his fellow Maou.


Meanwhile in the Fallen Angels territory inside a custom made dojo two fighter can be seen fighting each other in a high-speed fight.

The first combatant is a tall man appearing to be twenties with an average build, black hair, golden bangs and black goatee. His eyes is purple in colour and currently he has twelve jet-black feathered wings behind him similar like the one whose was killed by Issei has.

While the other combatant is a young girl that look to be 3 or 4 years older than Issei with dark silver hair that went past her shoulder and ice blue eyes. She is now on the ground panting as the armor that she wears, white draconic armor with blue gem and a pair of translucent blue colored dragon wings on her back while her armor has several cracks all around and her helmet is shattered.

"Come on don't tell me this is all you can do Valira" Taunted the winged man.

"*pants**pants* No old man I can still go" She said as she try to use her wings to lift her up.

(No Valira I suggest you stop fighting Azazel now your body can not go any longer) A disembodied voice can be heard coming from the now named Valira

"*sigh* Albion is right Valira you need to rest." Azazel said as he float down

"No I can…" Valira retort was cut as she along with everyone in the Grigory HQ feel as the Underworld tremble and a roar is heard.

"What was that?!" Azazel asked as he regain his bearing and when he turn to make sure Valira is alright he was surprised with the view of Valira shaking on the floor grabbing her leg close to her chest and he could see tears flowing from her eyes.

Immediately he rush to her in order to comfort her and calm her down as this is the first time he see the strong willed and stubborn Valira in a vulnerable position.

"What is it?" He ask in a soothing voice.

"I…I'm s… scared" She reply with a trembling voice as she grab Azazel for comfort and protection.

"Albion what happen to her" he ask the dragon inside of her.

(I… I have n… never feel s… such power, it scared m… me to think of the owner of such power) Albion said, as he could clearly feel the power behind the roar that could rival; no surpassed Great Red.

Now that has Azazel in alert as even the powerful Heavenly Dragon was scared of this creature.


{Unknown Location}

A girl can be seen standing on a building watching the sky. This girl is a cute young girl with long black hair down until her hips and gray eyes. Her ears differ from a normal human's as they have pointed tips. This girl also wears black Gothic Lolita style dress with big ribbon behind her and her torso is left bare with only black tape in cross 'X' shape cover her nipples, wears frilly bloomers instead of pant and without any foot wear.

As she watches the sky her dispassionate eyes suddenly widen as she could feel the world tremble as a roar is heard.

"Powerful. More than Baka-Red" she said to no one as she looks toward where to source of the power.

All over the world those who is aware of the supernatural can feel it; the power behind the roar that shake the world literally from every gods of any pantheon to lesser being of supernatural origin but none were more affected by said power more than the dragons.

As all dragons all over the world shake in fear of this new power and even more when all; no the entire world heard what come after the roar. A sentence from a foreign language that nobody know can be heard and all know in instinctual level that this being is powerful and to be avoided at all cost.

"Zu'u los Alduin faal Lein Naakin ahrk pah fent qiilaan tum wah zey!" That was the sentence that they heard several minutes after the roar.

Fahvos vuth zey nol dii dez Bormah? = Why stop me from my fate Akatosh/Father?

Yeah Issei now have Alduin sealed inside his Sacred Gear formally know as [Charm Speak] my OC SG (don't know if it existed or not) but changed because of Alduin presence becoming the [Dovah Rel] translated as Dragon Ruler allowing Issei to use every Thu'um that Alduin know even the one Miraak use, but it will drain his stamina to use and have a recharge time after every use depending on the Thu'um used.

And yes Great Red is scared of Alduin since in Skyrim Alduin is know as the God of Destruction and The World Eater, with the use of his versatile Thu'um that he can use to actually absorb SOUL for him to feed to creating a deadly Meteor Shower to crush his enemy; yeah without the Dovahkiin he is OP and unstoppable in the DXDverse.

As for the pairing for Issei it will be the canon harem (Rias whole peerage will be all female in this story) with the addition of female Vali, his OC cousin (the wielder of BG), female Kiba (Yumi), female Gasper and Kuroka [Not final pairing].
