Prologue

(3rd POV)

*Toilet discharge sound*

"Haa~, I feel lighter." A teenager sighed in relief after shitting.

(E/N: (⌐■-■) )

Then he returned to his room and sat on his chair, and continued his anime marathon. His room was simple and didn't have many things, besides the shelf full of anime/manga or game-related objects.

Hours passed and soon the night came, the young man paused the episode he was watching and looked at hours.

" It's almost midnight and tomorrow I have school" The high school student said before looking at the paused video. "*Sigh* Why can't my life be like those in anime? They seem to have so much freedom and can live without a care in the world, except a few though…"

*Ding!*

"Hmnn?"

The teenager suddenly received an email and he opened it out of curiosity.

"I heard your wishes, if you want them to come true, you have to beat me in a chess match!"

The teenager read out loud the message and there was a link attached to the message.

'Is this virus?' He thought.

This was very suspicious as the box where the sender's email was supposed to be was all blank.

'Better be safe…'

He was about to close the email, but then suddenly stopped.

'Wait, how did it know what I want? And precisely at this moment?!''

He read the mail again and confirmed and it was still the same.

'The timing was perfect. Not to mention this situation is very similar to the first episode of No Game No Life.'

He pondered as he looked at the link.

'Besides, he challenged me to a chess match…'

Although he usually doesn't play chess, he never lost in a match against anyone, and his father and classmates said that he was a genius and talented in it.

"Nevermind, I will just accept this challenge and I doubt I will lose to anyone. Besides, I feel that I will regret this if I don't accept this challenge."

Then he clicked the link and of course, after checking if his firewalls and anti-virus were on in case of someone hacking him.

(Timeskip - 3 Hours Later)

"Damn, what is with this guy? It's like he planned 7 moves ahead, but it lost anyway because he underestimated the power of the pawn."

'Now time for my reward and then to doze off afterwards…'

He stood up from his chair and went to the kitchen and grabbed something to drink.

When he returned, he saw an old man sitting in his chair looking at the screen. He had long white hair and a white robe, and his eyes were shining golden.

"...Hmnn...Who are you?" He asked cautiously since it was obvious that this old man wasn't a human.

"So this is how you won…" The old man ignored him as he didn't move from his place and kept muttering words as he looked at the screen.

'Am I hallucinating? I am sure that I never took drugs or anything like that' The teenager thought as he looked at the old man.

"Nah boy, you aren't hallucinating" The old man said without looking at him. "I am what you mortals call a God, not like those inferiors that humans created in their imaginations. I am the Origin as well as the End of everyone and everything, but you can just call me ROB like what you humans started to call me recently since your mortal brain would make a good juice if you ever heard it"

"So ROB...is what you said true? That you will grant my wish if I win you?" The young man hesitantly asked, which finally the white old man turned to look at him.

"Yes, though I never imagined that I would lose to a random mortal in this mundane world…" His voice contained no anger, only amusement for the mortal in front of him.

"So what will it be then?" The teenager asked eagerly.

"You are surprisingly taking all of this easily" The white old man chuckled as two wheels appeared on his side's out of nowhere

"What are those?"

"These are the wheels that will decide your fate." He flicked his fingers and many words appeared on the wheel.

"In the first wheel, you can roll 3 times with no refund or anything like that and you can get anything, from bloodlines, skills to a system."

"And in the second one, it will decide which world you will go to, note that it can be a crossover or an AU." The teenager nodded and the old man continued.

"Then let's not waste any time and roll!" The old man said excitedly as he spun the wheel.

*Thud* *Thud* *Thud* *Click*

"Hmnn you sure are a lucky fellow…" The old man muttered.

"What did I get?" The teenager asked eagerly. The old man smirked and then showed him.

"Servant Ruler: Amakusa Shirou Tokisada Inheritance" He read it out loud and widened his eyes.

'Yes!' He celebrated in his mind. Amakusa Shirou was one of his favourite characters in FGO and Nasuverse, so he obviously was very happy about it, even if he wasn't one of the strongest servants.

The old man smiled at him and clapped his hands.

"Then let's continue"

The wheel started spinning again and after a few seconds, it stopped again.

"A Dimensional Chat Group!" The young man exclaimed in surprise.

'This is getting better and better!' He thought, but then it hit the sudden realization. 'But I hope that the chat members won't be evil or crazy characters though'

"And then the last spin!" The old man spun for the third time.

*Thud* *Thud* *Thud* *Click*

"What did I get?" He asked hesitantly to the old man, which he just grinned at him.

"Your luck is awfully astonishing, this generation White Dragon Emperor" The old man said while grinning at him.

The teenager widened his eyes.

"Does that mean…"

"Yes, congratulations on getting one of the 13 Longinus Sacred Gear, Divine Dividing." The old man started clapping.

The teenager smiled widely as he celebrated

"Now finally, we will see what world you will end in." The old man said as he spun the other wheel.

*Thud* *Thud* *Thud*

'Please don't let it be SNK or Re: Zero please' The teenager prayed mentally.

*Click*

The teenager immediately raised his head and saw which world it landed.

"A crossover…" He read it out loud.

'But with what?'

"Now, good luck on your journey, young man." The old man suddenly said.

"Wait, I don't even know wha—"

He couldn't even finish what he wanted to say as he blacked out.

(MC POV)

"Ughh…" I groaned as I slowly opened my eyes.

'Where am I?'

I slowly looked around and noticed that I was inside a moving train which was surprisingly empty, with a travelling suitcase next to me.

'Where is this heading to?' I asked myself but then suddenly I felt a rush of memories entering my head, causing me a headache.

They were memories from "this me" and another from Amakusa Shirou, from when he was alive.

"*Huff* *Huff* Damn…" I cursed as I held my head to endure the pain.

Apparently, my name is Kotomine Shirou and I am heading to "Suimei University of the Arts" in Tokyo to attend high school. "I" was raised by a retired old exorcist in Kuoh, who taught me some basics about the supernatural world and taught me to pray to God if I ever encounter danger. And, at his death bed, he wished for "me" to attend this school and live a normal life, to which "I" agreed.

He also said that he already made the preparations and I will sleep in a dormitory that he arranged with an acquaintance of his.

"*Sigh* It is finally gone, but it will take a while for me to digest all of these memories"

Then I looked at the announcement board and I had still a few hours until I reached my destination, so I decided to learn more about myself.

"DxD and Sakurasou huh…" I muttered, these were one of the worlds that I know in this crossover so far.

"I guess it's time to awaken him…" I muttered as I got up from my seat and went to the toilet.

"Wow, I look exactly like him…" I muttered as I looked at my face in front of the mirror. I had black hair, dark golden eyes and pale white skin, and a silver holy cross earring in each of my ears, looking exactly like Amakusa Shirou in the 3rd Holy Grail War.

Then I closed my eyes and focused on myself.

'Think of the most powerful thing…'

Then suddenly, I felt something inside me. I tried to pull it out and a pair of blue energy wings held by a white metal thing, it was Divine Dividing, and surprisingly, it didn't destroy anything inside the cabin.

(A/N: Anime logic…)

"Hmm? So, my host finally awakened me! Let me introduce myself! My name is Albion! The Vanishing Dragon! One of the Heavenly Dragons! Holder of title The White Dragon Emperor!"

I heard a deep male voice coming out from the pair of wings

"Nice to meet you, Albion!" I said excitedly, after all, I was talking to one of the coolest dragons in my opinion.

"Ho? Interesting! You are the first of my hosts to react like this!" He said and I could tell that he was curious.

"Most of them are freaked out or experience a period of denial, but you… you are excited?"

"Well…" I said while scratching my cheek. "It's because...hmmn… never mind, I think it's faster this way" I said as I focused on my memories and sent mentally more relevant ones to him.

"..."

"Hmnn…"

"..."

"Interesting...to think that the multiverse really exists and we were just mere fictional characters…"

"You aren't mad?" I asked curiously

"Mad? At the fact that our lives were decided by some horny dude?" I nodded. "Don't be ridiculous, this isn't much different from others me mentioned in the books, even if he was the one who wrote what you call "DxD", in the end, I am still me and that is what matters"

'Wow, I never thought that he would give such a deep speech' I thought as I retracted the wings inside me.

"Now Shirou, what will you do now?" Albion asked me.

"Well, I have to go to the dormitory first and maybe check the chat group..."

*Ding*

"Speaking of the devil…" I said as I took out my flip phone from my pocket, then it suddenly morphed in my hand to a super futuristic phone that was more advanced even in my old world.

[Do you wish to join the Dimensional Chat Group?]

[Y/N]

I grinned and immediately pressed "Y".
