On an empty island, Irina Shidou was looking at the sunset.

Irina looks like a young woman with violet eyes. She has long chestnut hair that she lets down.

She was wearing a black robe and behind her back were 6 pairs of Angel wings. Her wings weren't white but black could be seen in them.

On her beautiful face, there was an expression of indifference that made it seem like she didn't even feel anything.

She had it for over 12 years.

"So, this where you were. "Irina turned her head in the direction the voice came from and saw a young man with chestnut and brown eyes flying towards her using his Dragon wing and Angel wing.

That boy was Shin Shidou, her son.

Irina had a blank expression on her face which didn't change even a little.

Shin was looking at his mother with hurt visible on his face.

"What do you want, Angel Shidou? "Irina turned her head to the sunset as she spoke to the young man as if she didn't know him.

Shin felt his heart break as his mother spoke like she didn't even care he was there.

"I'm here to talk to you. You disappear before Issei's funeral. "Shin explained which confused Irina a little that the boy was referring to his father in such an informal way because he never did that.

"I have nothing with the funeral of that man. He was nothing but a shell of his former self. The Red Dragon Emporer, the World's Savior, and all the other names. I couldn't even meet him for weeks even months. "Irina said as her expression changed to that of sadness as she was crying.

Irina flew down to the ground as her wings disappeared she remembered every time she saw her husband for the last few years including the last time she saw him as her husband.

Shin looked at her shocked as this was the first time he saw his mother break.

His mother was the unbreakable guardian of Heaven, the strongest Angel to ever exist, and her title Tyrant.

"Issei-Kun wasn't a savior, a hero, or anything like that, he was nothing more than a..."

"...a slave. "Shin cut his mother as she looked at him.

Irina looked up at her son and hugged him as he returned the hug while both of them were crying.

"I'm sorry, Shin-Kun...They took the man I love and turned him into a slave to their peace. "Irina was breaking as she remembered when she found out that Rias allowed Issei to be killed and tricked him into becoming the crimson-haired bitch's slave.

She never asked a question.

None of them did.

Not his supposed friends.

Not his lovers.

Not even his parents.

And she was as guilty as any of them.

Irina felt like she was drowning when she was snapped back to reality because of her son's voice.

"Do you want to change this? "Shin said taking his mother by surprise.

"Change what?"Irina asked fearing that she knew her son was asking about it.

"Change how this word turns up to be. "Shin said with a sad smile.

It took Irina a moment to decipher what Shin was saying and then she gasped. "You didn't..."

Shin smiled sadly as he took a blue-colored sphere with a yellow clock on it.

"I did keep it. Regress is unsensible, undestroyable, and most importantly unstoppable. "Shin said as he placed the sphere in Irina's hands which were already shaking.

"But if I use this, you'll..."Shin didn't allow her to finish as he warped her in a tight hug.

"Yes, I know but Father deserves a better life than this one along with everyone else except them. "Shin said as tears fell from his mother's eyes.

The sphere began shining golden.

Irina made no moves to stop her son knowing that it was futile to try.

"We're both too stubborn to stop. You must've made sure that anything I do is futile. "Irina thought as she was holding her son until she couldn't.

"One last thing, find them before anyone could. Use every means necessary to win. Never be Tyrant and save the world from them. "Shin told his mother but he already knows that his mother wouldn't settle for any result but a complete victory.

"See you soon, my little Angel. "Irina said with a sad smile as a white light engulfed both of them.

.

.

.

Irina gasped as she woke up.

She was breathing heavily and looked around and saw that she had woken up inside her old bedroom in England.

Irina went to the bathroom and looked at her reflection in the mirror.

After a second, she took a breath and spoke in a whisper.

"Skills. "

After almost 10 minutes of laughing, Irina stopped in her tracks took her phone out, and smirked as she saw the date.

"Not long after Issei-Kun became a Devil because of that crimson-haired bitch. You aimed flawlessly, Shin-Kun. And Olivia's power gets activated. I'm going to count the days from to give birth to you again. "Irina said with a sincere smile.

"Show me my LP. "Irina said praying even though she was never aware of it that her power was still stacking LP.

LP: 3212500

Irina fell to the ground from the sheer amount of LP she had.

"How is this...I am only supposed to get...when doing something that...pleasurable and that damm Skill isn't here either. "Irina laughed but she was still trying to process what she was seeing.

Irina calmed down and noticed that her parents should wake up in an hour.

'It's a good thing that Skil isn't here? what should I do first? Get new Skills and find a way to contact Issei-Kun but how...?"Irina thought until the memory of her first Christmas after the alliance came rushing to her head.

Masaomi Yaegaki and Cleria Belial.

'Who would've thought you would help me?'Irina almost laughed at the irony.

"I better improve my body's condition first.

Irina saw that the total amount needed for her new Skills is 63000.

Irina took a deep breath and then whispered, "Create."

Irina felt her body burning from the changes that are currently happening to it.

Most people would've passed out.

But Irina Shidou isn't like most people.

She suffered anguishes that would've made many Gods beg for the sweet release of death.

Irina bit her lips as a symbol was being formed on her chest.

After less than 5 minutes, Irina's body began calming down as her Skills became permanent which was showing on her skin as the evidence of her ice Skill was on her chest.

LP:3212500-63000=3149500

Irina was trembling from the pain despite her mind being able to withstand the pain, her human body couldn't. She slowly walked to the bed.

Irina threw herself to the bed as she was losing consciousness.

"Tomorrow,...the...easy part...will start. "Irina said with a smile as he fainted.

.

.

.

An hour and a half after fainting, Irina woke up and jumped out of bed immediately.

She began checking herself.

"No noticeable physical changes except the mark on my chest. "Irina said as the mark disappeared. "Thank God, I didn't get a tail. "

"Also the amount of mana I have right now is almost equal to Ingvild when I met her. "Irina decided to find that Half-Devil as soon as possible.

"Mama and Papa should be awake by now. "Irina thought as she was washing her face.

Irina was anxious about meeting her parents since she decided to cut ties with them but she knows that she must do it to move on.

She was feeling a little bit guilty of what she was about to do.

After dressing up, Irina got out of her room and went to have a talk her father wouldn't like.

Walking out of her room, she saw a middle-aged man with light brown hair and blue eyes sitting on a table drinking cofé.

That man was her father, Touji Shidou.

In front of him, sits a woman with violet eyes and black hair, and a face almost identical to Irina's.

That man was her mother, Elen Shidou.

As soon as they noticed her, they smiled.

"Good morning, Irina-Chan. "

"Did you sleep well, sweetie?"

Irina's face was stony and that made her parents look concerned.

"Masaomi Yaegaki and Cleria Belial. "Irina said with a low voice.

Her father was shocked to hear these names coming from his daughter's mouth.

"Where did you hear these names?"Touji Shidou asked in a serious tone but Irina could tell that he was afraid.

Irina didn't fake the disappointed look on her face.

She never did.

She understands why the forbidden lovers were executed but she can never accept it.

After all, Irina is always honest about everything.

"I didn't want it to be true. "Irina said under her breath making Touji gap as he realized that his daughter knew about his shameful act against his student and his lover.

Irina got up from her seat and began leaving the room.

"Irina, wait! "Touji exclaimed at his daughter not adding "-Chan".

Irina turned her head giving her father a cold look.

Touji and Elen froze as they saw the look on their daughter's face.

"I need...some time to think. "Irina said leaving no room to argue.

Elen was oblivious about what was happening in front of her but she could tell one thing.

Whatever is happening is terrible for Irina to make that face.

Elen decided to ask her husband as he seemed to know what was happening.

Irina left the house after taking an apple from the kitchen.

Irina used her ability on the apple to make her capable of sustaining her hunger for the day at the cost of merely 50LP.

3149500-50=3149450

Irina wasn't looking even where she was thinking about her next moves carefully as what she was planning on doing was very dangerous.

"I'm going to make an enemy of...probable 75% of the Supernatural World. "Irina smiled at the thought.

After all, she did once when the world was stronger.

One would be crazy to think like that and smile but Irina had an advantage no one else could have.

It's not her knowledge of the future.

It's not her Skills.

It is the fact that she's a normal person.

She doesn't have a Sacred Gear, a rare bloodline power, or the benefit of being born into a noble family.

She can do many things and no one would believe she did them because she wasn't born with the ability to do so.

"As long as I keep quiet, I will have enough time to become strong enough and I will have enough time. "Irina thought as she was walking.

Irina smiled as she passed people and as soon as she wasn't visible to anyone, she vanished using her Instant Transmission.

Nidavellir:

Irina found herself in a mountain area that was covered in dark.

Before her feet touched the ground, she used Flight and Illusion Magic to make sure she didn't.

Irina knew that the Dwarves used vibration detectors to find out if anyone were to set foot in their kingdom without permission.

Irina flew at a slow pace to avoid detection.

Irina was slowly making her way threw the houses which were quiet as they all were asleep.

Irina lost the smile on her face as she realized that no guard was patrolling.

"Useless pride. "Irina thought as she followed a sound.

"Create a Copy Talent Skill and add the effects of the Skill can be used from a small distance, the ability to take more than one Skill, a way to negate the cooldown and allow it to be implanted on another being or a Skill as long it's possible. "

You can activate this Skill by touching the target or from a 3-meter distance. Cooldown: 30 Days. Cooldown can be removed by using 1000 LP or paying 10000 USD.

Irina was dumb folded by what she was seeing.

"Guess money can buy anything. You can even bribe Skills with it. Create Skill. "Irina thought as she sighed.

3149450-4000=3145450

Irina stopped when she felt a familiar aura.

She flew as fast as possible and kept as quiet as can be.

When she reached her destination, she saw a black-haired Dwarf with a wine bottle in his hands.

"Pass out from drinking inside a forest. Why don't I find it hard to believe that a king acts like this? "

Irina rubbed her head and continued flying until she was a meter away from the Dwarf King Eitri.

"Activate Skill Copy Talent. Copy the blacksmithing and drafting Skills and merge them while Adding them into Pocket Dimension/Inventory; Advanced. "Irina didn't hesitate to use her Skill.

Sub-Skill Created

Cost: 100000

3145450-100000=3045450

"First step complete. "Irina thought as she disappeared.

.

.

.

Irina transported herself to an empty building that was near her house.

Irina used to go there before becoming an Angel but stopped for a long time and the day she came back to it, she despised herself for doing so.

This place contained a gate that transported a lone Angel to the Nine Circles of Hell which were the most horrible prison God from the Bible ever made and was labeled a mistake by his most loyal Angels Michael and Gabriel.

That prison was kept secret by every Seraph as they were the only ones to know about it.

Irina knows how to control and destroy the portal but she can't do that until she goes into it.

Despite her better judgment, she knows that she needs to go there.

"I better make every minute in there count. "Irina thought as she tried thinking about the Skill that would help her the most.

"Create Asgardian Philology(Power Growth). "Irina said while asking herself the reason she created this earlier.

Asgardian Philology(Power Growth): The older the user gets the stronger they become.

Cost: 1500000 LP

Irina was shocked by the amount of LP she needed for this Skill but realized why she didn't make it.

"I instinctively knew that this Skill would cost too much. Okay then. Make it Temperley for 7 hours. "Irina said hopping for a better cost

Temperley Asgardian Philology(Power Growth): The older the user gets the stronger they become for 7 hours.

Cost: 7000 LP

"Decent amount. Make it. "

3045450-7000=3038450

Irina knew the final action she needed to take.

Irina took a deep breath as 12 Magic Circles appeared around her.

4 were Angel Magic Circles belonging to Michael, Gabriel, Zadkiel, and Barachiel.

4 were Fallen Angels Magic Circles belonging to Azazel, Lahash, Remiel, and Gusion,

4 were Devil Magic Circles belonging to Lucifer, Bael, Belial, and Leviathan. wi

This a Magic combination that Irina found during the most hellish time of her life.

The Magic that turned the World upside down once she revealed its existence.

Amplification

Irina was feeling her body changing as the Magic Circles around her were disappearing.

Normally, it would take a group of at least 12 with a High-Class Wizard's level an entire day to use this with the help of Angels by allowing them to connect to Heaven partly.

But Irina was the one who found it to begin with.

Her knowledge of Demonic, Angelic, and Fallen Magic is unrivaled.

Her knowledge of Senjutsu rivals that of the Sun Wukong of her time.

All of this allows her to use Angelification in only a minute without being detected and without linking herself to Heaven's System.

Irina opened her eyes and felt a familiar feeling on her back.

She saw a pair of pure white wings on her back proving her success.

Since Irina is currently cut off from Heaven, she has two facts that make her different from every other Angel.

The first one is that she's unable to fall as she's not bound by Heaven's rules.

Although it saddens her that the mark on her right arm isn't there.

The second one is that her strength can't increase like any other Angel by simply being one.

As soon as Irina's wings came into being, a blood-colored Magic Circle appeared under her.

From the Magic Circle, dozens of golden chains were launched at Irina restraining her movement.

Irina moved her hand a little as she used her knowledge to change the location she was transporting to slightly.

The Ninth Circle of Hell Teacher

Irina was flying while using her control over ice to protect herself from the frosty environment of the Ninth Circle.

She was using her control over time to make sure her mind was in link with her body because this circle wasn't meant for Angels to be in.

She was using Wothless to prevent the traps from activating.

She could feel her powers growing thanks to the Temperaly Asgardian Physiology she had.

She was feeling the years passing as she was getting closer to the center.

Irina knows this place too well.

Prior to her regression, She was trapped in it for 231 years before finding the way out.

This place has many confused rules of how time works.

Her 231 years was merely a day outside.

She hated this place too much.

It took her 11 years before her mind adapted to the cursed land.

It took her 30 years to find out that the exit was at the deepest part of the last Circle.

It took her 80 years to know about the layout and the purpose of each other Circle and pass the next.

It took her 70 years to adapt to the cold of the Ninth Circle and pass every trap falling tens of thousands of times; receiving deadly wounds each time she did.

It took her 50 years to leave the center of the Ninth Circle and escape.

Irina knew that she couldn't even make the slightest mistake as that could be the beginning of her never-ending suffering inside the most cursed place ever to exist. After 5 hours of flying, Irina looked at her back and saw that her pair of wings had doubled and she was feeling that she was near the third pair.

Her muscles also developed and now she has a

Inside this place, non-human bodies grow old very fast.

In the small timeframe of 5 hours, Irina Shidou's body grew by about 200 years.

In each Circle, the growth of the body goes up as you go down which only gets lower by the type and amount of power one holds.

It was the first defensive mechanism that was designed to keep living beings away.

Irina had three pairs of wings and was near getting the fourth when she entered before regressing and despite that, her body had grown over 100,000 years in the time she was inside this place.

In a way, she was the oldest Angel to exist.

That fact made Irina lucky as her body grew by a mere 200 years knowing that she got only a pair of wings that she got just recently.

Irina managed to avoid all the traps and landed deactivating all her power and lowering her aura to barely that of a human as she reached the center.

Irina knew that this place was the trickiest part of her journey.

In The Ninth Circle's Centre, if you don't show respect and let go of all your power you are to be punished.

For Irina, this was the most devastating part as she was steps away from freedom, and the prideful nature that she gained during her stay condemned her to stay for 50 years.

Irina walked through the place her memories flashing through her mind as the final trap of the Circle.

Irina saw all the horrible things that she had done, that she saw, and the things that were done to her.

Irina didn't even pay them a mind as she already made peace with them.

After taking 13 steps, Irina reached a golden Magic Circle.

This place is the way out although she didn't leave immediately as she still has things to do.

Irina walked 7 steps to the right and arrived at a green crystal containing a golden feather and a black feather.

Those feathers were the main reason she entered this place.

Those feathers were the True King of the Devils Satan formerly known as the Angel Lucifer the Morning Star.

That one feather contained a small amount of his angelic and demonic power concreted.

Irina knew the moment she took these, her life would change forever.

This moment will be decided if Tyrant will be born again.


This story will likely be IrinaxIssei.

If this story becomes a Harem one; Irina will be the Alpha and Rias, Akeno, and Koneko will not be in it.

Can anyone give Skill suggestions?

As for the Feathers of the Fallen One, what should I do with them?

I have an idea but I'm open to suggestions.

I don't own High School DxD or The Hidden Dungeon Only I can enter.
