I Don't own Highschool DxD or any other elements I include within this fic.

Chapter 1: Prologue, Good-bye My World

Wake up, breakfast, go to school, go home, dinner, sleep, and wake up again...

These ordinary days keep repeating itself, it was always like this, no dreams, no fantasy. If I encounter something interesting, I always found myself on my bed, waking up from dream into reality.

Just when did I realize how dull this world? The hint already exist in my elementary school, on my middle school I be what people called 'Chuunibyou'.

The betrayed feeling of a child once he realize this world are different than the story he know is too big for me, my delusional started to felt real.

At those moment I don't care if I spend my entire life as Chuunibyou, but...

Once again, The reality crushed my little world as I grown up. People said I 'cured' from my Chuunibyou but to be honest I feel even more dissappointed in my highschool year.

Highschooler should be the most time to enjoy the youth but unfortunately instead being born from normal family, I born as the sole heir of famous company owned by my father.

Despite how many times I protest, my father insisted I should go to exclusive all-boys school where everyone there from high-standing family.

Forget about girls, I can't even had light conversation with them. Its always about business, responsibility, etc...

As you can guess, I don't have someone who I can call 'real' friend.

I feed by expensive food, driving by car to the school and home, tutored by the well-known teachers, in home there's butler and maid serve me.

From people's view, I must be the luckiest person. But I can't feel like that, I tried many times to accept this kind of life but it was futile. There's something missing, i knew this is selfish for me to think this way.

I yearn for street-stall food which I never ate, I yearn walking to school with my friend and stop by somewhere on way home, I yearn doing part-time work and taste my own earned money.

But this selfishness had to end, therefore today I placed my last hope in a paper.

I take out the paper in my pocket, it looks like an usual paper used at Tanabata's festival.

I found this inside my shoe locker along with letter...

"Write your wish here and tied under a tree at the shrine".

I don't believe it of course it must be someone's prank, therefore I placed my last tiny remaining hope in this small paper. Knowing it won't happen so I can crush the last of my childish dream.

As usual, there's nothing worth mentinoing happen in school. At the parking many expensive-looking cars waiting along with it's driver.

I sighed as I walked to my driver who waiting for me, he silently opened the backside door like a professional driver he is.

I give a silent nod of thanks as I walk in. Once he started up the car I said to him.

"Please stop by at shrine"

"But, young master. Your private teacher waiting..." He stated hesitantly, he must be don't want to be blamed by my father for my lateness.

"Don't worry, it won't take long" I reassuring him.

He reluctantly nodded as he drive the car.

'Yes, it won't take long at all' I thought as I look at reddish evening sun.

Its not take a long way from my school to the nearest shrine, after I told my driver to wait for a while I climb the stone stairs.

I can see the shrine gate not long after I started climbing. I haste my pace by running.

I reach the gate while panting slightly, the shrine is empty.

"There's so much fallen leaves here, when does this shrine last cleaned?" I voiced my thought.

'Oh well...' I shrugged "Let's just get done here".

I walked toward nearest tree on my right side, fortunately it's branch within my reach so I can tied it easily.

"Now that's done" I looked around, kind of expecting someone recording this and come out while laughing at me.

"This is a bit dissappointing" I muttered, even my last attemp doesn't produce a decent humor.

"...!" Suddenly I feel extreme headache "ugh...!"

I leaned my body to the tree but the pain won't stop rather it became worse.

"Haa...haa..." My breath ragged, this is the first I got this big nausea. I sometimes feel headache but this one on different level.

My legs finally gave away as I kneeled on the ground, my free hand gripping to the tree for support.

As my vision faded, I can see a pair of legs standing in front of me. But I don't even have energy left to look up.

...And finally I succumb to the darkness.

The figure kneeled near the fainted boy, the figure are veiled woman. Her face can't be seen much thanks to the semi-transparent white veil.

She smiled from behind her veil as she pat the boy's head.

The woman stand up and walked toward the tree, she extend her hand to reach the paper that tied to the tree, because she shorter than the boy she needs to tip-toed to reach it.

The paper facing backward before now facing opposite because it flipped by the woman with veil.

The woman had slightly surprised expression once she saw his 'wish' but her expression immediately changed into a smile.

"your wish shall come true" The woman spoke, but strange enough she had happy smile almost like its her wish that been granted.

The woman once again kneeled, she turn the boy's body gently so his back facing the ground.

Despite being passed out in pain, the boy expression are calm. It was shocked her to be honest, she knew that pain isn't ordinary pain that you can just brush aside.

"...As I thought, you're Interesting. Yarai-kun"

She placed her hand on his forehead.

Then a small light appears from her palm that touch the boy, the light became bigger and bigger then big enought to enveloped the whole area.

Outside the driver who waiting saw the light with his mouth opened. But he immediately snap out from his shock state.

"YOUNG MASTER!" He ran toward the shrine, he arrived at the shrine while panting heavily thanks to the running and nervousness.

"YOUNG MAS..." But he found nothing except lots of fallen leaves dancing in the air almost like there's huge gust of wind just a moment ago.

He didn't reach until a piece of paper covering his vision.

"This...is for Tanabata's" He said confusedly. He instinctly turn back the paper and saw the wish on the paper.

"I wish I was born In world full of fantasy"

Once Yarai wake up he saw the black sky, illuminated by single moon which are full round.

He tried to move his body but for some reason he can't, like there's something prevent him from doing that.

He tried to call out to someone but there's nothing come out from his mouth except something similar to baby's cry.

'...It can't be...' Yarai gulped, thank god at least he can swallow his own saliva. That mean he isn't dead.

'Calm yourself Yarai, there's no such thing as returned to baby's state in this world' He tell himself that, it must be a dream. A very lucid dream.

He waiting to wake up...

...Still waiting...

...Waiting...

...

"WHAT KIND OF DREAM IS THIS?! JUST WAKE UP DAMNIT!...AND..."

He cursed but in reality it heard as baby's wailing.

Caught in his own rant he didn't noticed something approach him. He only stopped his rant once he felt something touched his left cheek.

He turn his head slightly and saw a big puppy (In his baby's eye) licked his cheek.

"WOOF!" The puppy barked as it continue licked him.

"WAIT DOGGY! DON'T DO IT!" Even though this is a dream he didn't want to be drenched by dog's saliva. Eww.

"EX! WHERE ARE YOU" The puppy stopped its activity once a woman's voice can be heard from afar. Something Yarai thankful for that.

The puppy barked before running to the silhouette.

"There you are" the figure picked up the dog. It was a young woman who looks like around her late twenties. But what interest Yarai is a bundle on her stomach "Just where are you...?" Her next words stopped when she saw Yarai.

"OH GOD!" The woman practically running toward him. The middle-aged woman crouched near him.

Once she put down the dog, he pick Yarai up gently. Yarai feel strange when the woman pick him up easily, granted he's a baby now but it doesn't change the fact it felt strange.

"You poor baby" She cooed. "Why they doing something horrible like this". Yarai feel himself hugged by unfamiliar woman, but he didn't hate it.

'It feel like mother'

Yarai's mother died by giving birth of him, something that haunt him forever.

He unconsciously returned the hug with his small hands while a trickle of tears formed in his eyes.

"Finally I found you, Misako" A man's voice can be heard from the behind of woman called Misako "You're pregnant so don't make me worried..." He looked at the baby in her hand.

"Whose baby is this?" He put a smile as he pat the baby's head.

'When the last time when father pat my head like this before? I don't remember'

Misako immediately frowned "I found him here" She make gesture to the cold ground.

The man himself understand just with that and he rub her shoulder to calm her down.

'...Abandoned baby, huh?' Yarai thought 'It's no wonder they thought like that given the situation'

"Dear, can we...ugh!" Before she can finish her sentence, Misake grimaced in pain

"MISAKO!" The man cathed her before she fall "What's wrong?"

"My stomach...is hurt" She said while biting her lip, still hugged Yarai in her arms.

"Oh God!" The man immediately pick her up bridal style as he ran from the place.

Yarai don't know what to do, his body powerless "Hang in there!" his words come as cry but for some reason he saw Misako smile hearing his cry.

So Yarai decided to give her comforting words despite it won't come out perfectly from his mouth.

The man stopped near a brown car, it was an ordinary one but clean. He open the door next to driver's seat and gently put his wife on the chair and with haste he ran at opposite side to enter the car into driver' seat.

"Just hang in there Misako, we headed toward hospital right now". Misako only nodded weakly.

Fortunately it only takes five minutes to reach hospital, thanks to the short distance and reckless driver.

Yarai waiting from outside labor's room nervously with Misako's husband who don't lose in nervousness.

"Please Kami-sama, save my wife and my child" The man continously praying to the god. Given the cross necklace he wore Yarai can conclude he is catholic.

'I never believe in god but if you're there please save her' Yarai praying from the bottom of his heart forgetting the fact this might be just a dream 'Don't let the child lose the mother's warm'

After a long wait finally the door opened and a doctor appears with a smile.

"Conratulation sir, you had a beautiful daughter".

"Thanks you Kami-sama, Thank you sensei" A single tear fall from his eye.

Yarai watch the man sad smile 'Do my father also happy when I was born?'

"How about my Wife? Is She's alright?" He pressed once he remember.

"Don't worry, she's alright. Just exhaustion like usual mother after labor." That make him sighed in relief.

"You can see her if you want" The doctor move from the door, giving him a way.

After once again thanking the doctor, he walk past the door.

From the man's arms, Yarai can see a baby's sleeping next to Misako.

'Just a few hours ago, she still on her mother's womb' Yarai can't help but to admire the miracle of labor now that he saw it with his own eyes.

After the tension goes away, Yarai feel energy drained from him and close his eyes, sleeping.

"Misako" He called his wife gently.

"Dear, Look at our baby" She said in low voice as she still weak after labor.

"Yes, she's beautiful just like you" The husband said as he kiss his wife's forehead.

"Oh my, looks like Yarai asleep" Misako place her hand on Yarai's head.

"Yarai?" The man asked confused.

"This boy's name" His wife stated "We adopt him, right dear?" She said with a tone leaving none for argument.

"I knew you think like that" He said with small smile "Not that I oppose it of course".

"Not only we got daughter, we also got a son" Misako placed Yarai next to her newborn daughter.

"Yes, we truly blessed" Then he asked his wife "by the way, did you already decided the name for our daughter?"

Misako pondered for a moment "I leave the name for our daughter to you, I already named our son". Misako look at her husband with expectation.

"Actually I already doing names research for our child" He stated proudly "For a girl I decided Irina, what do you think?"

"Irina" Misako look at her daughter warmly "I like it"

"Then from now on they are Shidou Yarai and Shidou Irina"

He placed both of his hand to the babies's head, his wife placed her hands above it. She said to sleeping babies with tone full of love.

"Nice to meet you, Yarai-kun, Irina-chan"
