How did I get here you might ask? Simple. I died. Yes, died. At the age of 20 years old, I died. Not in the worst way though. It was quick, and painless… But the results were… messy…

You see, I was hit by a train. No, I didn't commit suicide. The thought had passed my mind in my teenage years, but I never went through with it.

The reason why I was hit by a train was because a little girl got her foot stuck in the tracks while crossing. I saw the train approaching and acted fast. I got the little girl free, but not in time to save her and myself.

I didn't have much to live for. Sure, I was a smart guy, but my chronic depression made for a certain lack of energy to do anything of note. I know that sounds like an excuse, but it's true. The psychiatrists all agreed. Anyway, I pushed the girl out of harm's way, and took a train right in the kisser.

Now, I thought that was it. I was never much of a believer. To me, death was a nap that you never woke up from. Boy was I wrong. Imagine my shock when I woke up in a black void, seeing a strange figure in front of me.

He/she looked kinda like Alien X from Ben 10… Yes, I like cartoons and anime, don't judge! Digression aside, I was extremely confused, not knowing what was going on. I mean, I DIED for fuck's sake! How am I here?! And who/what is in front of me?!

"Greetings, Chosen One." The figure spoke. At least, I think it was the figure. The voice seemed t come from all around me, and didn't really sound male or female. Almost as if many voices were speaking at the same time.

"Uuuh… Hi?" I greeted back dumbly. Wait, did he/she/they say 'Chosen One?' What does that mean? Chosen for what?

"I am the Creator. You, Child, have caught my attention." It, that's what I'm gonna call it, introduced. Wait, how exactly am I a child? And what are you the 'Creator' of?

"Um… Ok… How so?" I asked skeptically. I was really trying not to freak out here.

"You saved a little girl in danger, at the cost of your own life. Very few human beings would do that." The Creator explained.

"I don't see how that makes me very special. I'm hardly the first person to die saving another's life." I voiced my confusion. The Creator gave an amused chuckle at my words.

"Maybe not, but you did it because it was the right thing to do. No ulterior motive, no expectations of repayment, no selfish thoughts whatsoever. That is why I have Chosen you to be my next warrior." It explained.

"Warrior?" I asked in confusion, tilting my head. The Creator nodded and extended its hand forward, palm facing away from it.

A big flash of light appeared in front of its palm, making me cover my eyes. Once I new that the flash was gone, I uncovered my eyes and gasped in shock as I took in my surroundings.

The black void was no longer a void. It looked I was standing in the middle of space, seeing many different galaxies and stars. I almost thought I WAS in space, but I was standing on a solid, albeit transparent, surface. That, and I was breathing.

"Tell me Child, do you believe in the Multiverse Theory?" The Creator asked me. I gave the question a moment of thought.

"Well, I never saw any reason to believe or not believe it. Multiple versions of the same Earth occupying the same point in space, but vibrating at different frequencies, resulting in no contact between them. Is that the theory you're talking about?" The Creator nodded at my question.

"Well, it did seem a bit far fetched, but it's not the craziest theory out there. Why do you ask?" I asked curiously.

"Because, I have chosen you to become my newest Warrior." The Creator answered.

"That still doesn't answer my question." I pointed out.

"What exactly does being your 'Warrior' entail?" I asked.

"You will travel along the multiverse, living a life in one world after another, for eternity." My eyes widened at the answer.

"Eternity?" I exclaimed in shock.

"Indeed. As one of my chosen ones, you will be placed in a new universe, live your life in said universe until you die, and then be placed in the next universe." The Celestial-Sepian look-alike explained. My eyes were wider than dinner plates and my hands were gripping my hair. How on any Earth can this be real?!

"I can see you need time to process this. I will return when you have accepted the truth." The Creator spoke after a moment of silence. Before I could stop it, or at least try, it disappeared in a flash of light, ignoring my yells for it to come back.

And so started a long period of waiting… And waiting… And waiting… And waiting… I yelled for the Creator to return a lot in those first few days. At least, I think they were days. It could've been longer, or shorter. I never got hungry, or sleepy. It was extremely quite, and boring. I gave up calling for the Creator to return eventually. To pass the time, started counting the stars. That got old real fast. After that, I tried walking in a straight line continuously. As I expected, this void was infinite, just like space. I don't know how long I was alone. Maybe long enough to lose my mind, I don't know. Eventually, I just lay on the ground and looked straight up.

I started thinking, about everything. My life, how I lived, what did and didn't do. What I knew, what I didn't. Who I met, and didn't. What I saw and didn't. Even ridiculous things like what foods I ate and didn't. Eventually, my thoughts the reached the day my life ended, and I found myself in this void. The Creator said that it would return when I accepted the truth. I've accepted that I'm dead. I've accepted that the multiverse is real. What else? I know what else. I'm now bound to the Creator, aren't I? A slave. Well, not really a slave. Servant maybe? Nah. It referred to me as its 'Warrior.' So, I'm like a personal Knight then?

At first, the thought didn't much appeal to me. But, I started thinking about what I get out of it. I would live forever, so to speak. Of course, I would eventually die in each universe, but I would be reborn into the next and the cycle would continue indefinitely. That's not a bad way to live. Imagine all the things I could learn! Different languages, different Martial Arts, so on and so forth. All I'd have to do is serve the Creator. Is that really so bad? It saved me from death, so maybe this new life could be a good. Of course, I'll miss my parents and family back home, but I didn't really talk to them much. It won't be the hardest thing for me to move on. Not the easiest either, but still.

"I see you have accepted the truth." A familiar amalgamation of voices spoke. I sat up and turned to see the Creator. Standing up, I faced it and nodded.

"I'm ready to serve as your Warrior, Creator." I said as I knelt. I wasn't sure if I was supposed to, but better safe than sorry.

"Rise my Warrior. I appreciate the respect, but there is no need to bow or kneel. I am a mentor, not a master." The Creator explained. Good to know. I stood up faced the Creator, ready for my first task.

"What now?" I asked in curiosity as I walked over to the Creator, standing beside it. It extended its arm, and created a bright silver, swirling portal.

"The multiverse is not as split as one would think. There are small connections that bind some worlds to others." The creator explained.

"Such as?" I asked.

"A person could have a psychic link to another world that they mistake as imagination. Such as JK Rowling in your world. She had a Psychic connection to another world that she wrote about in her books." The Alien X copy explained.

"You're telling me Harry Potter is real?!" I exclaimed in shock. Never would have guessed that.

"Indeed. Along with most, if not all stories that authors and artists invented." Creator answered. An image of me getting my hands on the Omnitrix, or being trained by Batman, or even losing an arm and a leg using alchemy came to mind. THAT was a weird thought.

"The first world I will send you to is one that you are familiar with. You will be provided with a place to stay whilst not working, and the skills you need will be taught to you by the people you align with." The Creator explained as it stepped aside for me to enter the portal.

"Understood." I said with a nod of understanding.

"Good luck Warrior." The Creator said as I entered the portal.

I opened my eyes as I felt the light of the portal fade. I found myself in the living room of a very plain-looking apartment. Two couches, one 2-seater, one 3-seater, sitting across from each other with a flat-screen television in between the ends, making it easy for all who sat to see. The kitchen area had a large window-like hole in the wall that made the living room visible, and there were 3 other doors. I checked each one, finding them to be one bathroom, one bedroom, and one master bedroom with its own shower room. Not an overly fancy apartment, but it was nice enough that I wouldn't mind living in I for about 5 years before wanting to move.

I went over to the kitchen area and explored the cupboards. I groaned when I saw that they were void of anything edible. There were mugs, plates, cutlery and the like, but no actual food. That means I'd have to go buy food. And that means I'd have to work for money. I had a job back home, computer programming, but I could do that from my bed, so it was ideal for me. And I got that job thanks to my Dad who recommended me to his boss. Over here, o don't have any qualifications. At least, I don't think so.

I was pulled out of my musings when I saw an envelope on the kitchen counter. Tilting my head in curiosity, I picked it up. My eyes widened in shock when I saw the symbol that was on it. A pitch black Raven figure, with its wings spread, and yin-yang on its chest, where the black area was purple instead, as well as the dot in the white half. It was a symbol that I designed. I even had it tattooed on my left wrist! I wonder how the Creator new about this? Then again, he/she/they probably knows a lot. I opened the envelope and read.

Warrior

If you are reading this, then you have arrived in the world I placed you in. You will find that it is very different to the one you came from. In more ways than one. I have little doubt that you will recognize this world soon enough.

I've given you knowledge on reading and speaking the language that the country you are in speaks, as it is not England.

In this envelope, you will find a credit card, and an ID card. You need not worry about money limits, but it would be best to not be too reckless.

If you do your job well in this world and the others, you may be able to return to your home world. You will have to earn it though. Do not tell anyone where you really come from, or your real name.

This world needs you. You will know why soon enough.

Best wishes,

Your Mentor

PS, you may want to look in the mirror. That's not all that has changed though.

I raised my eyebrow at PS, wondering what that meant. Shrugging, I walked towards the bathroom and entered, completely calm. That changed however, when I looked in the mirror…

"What the fuck!?" I exclaimed as I saw myself. I looked so different! Before, my hair was brown, my eyes were blue, I had a bit of baby fat on my pale face, and I was a bit overweight for my age.

Now, I was completely different! My hair was black, my eyes were mismatched, left being dark green and right being dark brown, almost red, I didn't have much baby fat anymore, and I was a little more tanned than before. It still definitely me, my face, but different. Almost as if I dyed my hair, exercised, got contacts and spent more time in the sun.

I took off my T shirt, which was plain black, and gasped at my figure. I now had four pack abs, decent biceps, and rather broad shoulders. All in all, I looked pretty good!

"Nice." I said with a grin. Maybe this new me will help with my social anxiety. I was pulled from my musings when I heard a rumbling from my stomach.

"Ok, I need something to eat." I told myself with a sigh as I rubbed my stomach. I had no idea how long I was musing around in that void when the Creator left me alone. Must've worked up an appetite.

So, I grabbed the key to my new apartment from the hook in the living room, and took the credit card and ID out of the envelope from earlier. Curiously, I looked at the ID to find out my new name. Takeo Himekawa huh? Definitely Japanese.

The Creator delivered on that lingual knowledge. I could read the ID as if it were plain English! Cool. So, my stuff now in hand, I left my apartment, which was room number 304, left the building, and headed towards the nearest super market. As if by a work of fate, it happened to be a 5 minute walk away. I think I'm going to like this new world.

Wow, Japan is awesome! Before I went into the super market, I decided to stop by a fast food restaurant. I was REALLY hungry. I enjoyed a simple burger and fries along with a sundae. Don't judge. I have a MAJOR Sweet tooth, which was the main cause of my overweight back home. Now, as long as I watch myself and exercise, I can enjoy sweets again. Yay!

Anyway, after paying for the meal, I went to the super market to get some groceries, along with some other essentials. Bread, milk, eggs, stuff like that, along with a few toiletries and some clothing. Right now, I was wearing a pair of black jeans, a plain black T-shirt, and a pair of black boots. Yes, I was a Goth in high school, and I maintain it to this day. Sue me.

The walk back to the apartment was a little slower than the walk to the market, but that was just because I now had several paper bags to carry. It didn't cause much trouble, and the walk wasn't so bad. I managed to get back to my apartment on the third floor, 4th apartment.

As I got my key out of my pocket, I heard a rather chipper voice call "Hello there!" out to me in Japanese. It gave a little shock, but I recovered easily. I turned saw a pretty black-haired woman jogging up to me down the hallway, a happy grin on her face. She wore black skinny jeans, dark blue heals, and a blue crop top, showing off her midriff.

I felt a blush sneak its way on to my face as I took in her figure. She was gorgeous, with long black hair that went down to her waist, and beautiful purple eyes. Her hourglass figure was painfully obvious with her crop top, which seemed to fit perfectly around her large, round breasts. And her legs were long and flawless. I internally smacked myself to keep my mind from wondering.

"Hello there." I greeted in Japanese with a smile as she arrived. On the inside, I was really nervous. I mentioned before that I have social anxiety, especially with pretty women, but that was never much of a problem because women never approach me. Now, I don't look like a loser that would be a waste of their time, so this new body might not be the great thing I thought it would be.

"Hi! So, you're my new neighbour, huh?" She asked with a friendly smile.

"That I am." I responded, smiling in kind as I placed some of the bags I had down.

"You have quiet an accent there, where are you from?" She asked curiously.

"I was raised in England, but I was born here in Japan. Name's Takeo Himekawa." I introduced myself as I held out my hand. She smiled brightly and shook it.

"My name is Yuuma Amano. Nice to meet you." She introduced herself cheerfully. I paled when I recognised the name and hid my gulp of terror.

"Well, nice to meet you Amano-san." I responded, smiling nervously. She raised her eyebrow in confusion.

"You OK? You look a little pale." She said, a little bit of concern in her voice. I nodded as I opened my apartment door.

"Yeah, I'm just still feeling the effects of the flight. Air travel was never really my favourite." I lied with a slightly nervous chuckle. 'Yuuma' giggled in amusement.

"Well then, it was great meeting you Takeo-kun. I'll let you get back to settling in. Bye!" She chirped as she turned and walked away, unintentionally swaying her hips as she walked.

I hurriedly grabbed all of my shopping bags and rushed inside my apartment, locking the door and securing the chain. I let out a breath I didn't know I was holding, and slid down against the door to the ground. I was terrified right now. Why? Because I just figured out which universe I'd been transported to by the Creator. I was in the world of Highschool Dxd.

Now, under different circumstances, I'd be excited. But, the reason I know that I'm the aforementioned world is because I also know exactly which character I bumped into. 'Yuuma Amano' was an alias used by the Fallen Angel Raynare when she went undercover and met Issei Hyoudou, the main character in the anime. What happened, you might ask? She killed him. A nice, big spear of light through his gut. Fantastic. I'm still only human!

Wait… Am I? The Creator never mentioned giving me any kind of powers, but he/she/they did mention something other than my appearance changing… so, am I still human? Even if I'm not, I do NOT like that I met her. Why? Because she's using her fake name. That has to mean she's still undercover… right?

So, what do you guys think of my Self-insert? Is it OK? It is my first Self-insert, but not my first fanfic. I have another account, but I've abandoned that one.

If you enjoyed this, please leave a review! I will upload the next chapter at 10 reviews! Or when I finish writing chapter 3, whichever comes first.

Ciao for now!
