Re:Life 1-1: I Went Back In Time

Hyoudou Issei — that is my name. My parents and friends at school call me "Ise".

I'm a third year middle school student who is currently staring at the newly opened school in Kuoh Town.

Kuoh Academy is the name of the school. In the past it was an all-girls school and rumors of this particular school going co-ed had spread throughout the region like wildfire. A lot of my friends especially males wanted to attend this school next school year, well, for obvious reasons immediately applied.

As a male, I sympathize with my fellow genders especially my two best friends, Matsuda Eiji and Motohama Daiki. The guys had their heads filled with fantasies about being surrounded by beautiful girls that would fawn over them, and grant their carnal desires.

The same goes for me for I, Hyoudou Issei is a proud oppai loving pervert. But my reasons for attending this school is way beyond than my perversions and dreams of surrounding by heavenly oppai.

Looking at this school brings back memories.

Memories that are a part of me as long as I live.

I turned away hastily when I sense a dread feeling. It is a familiar feeling, a feeling that I felt in the past. Four energies though different in levels, they were the same.

Without looking back, I leave the place as soon as I my eyes hovered at the four girls walking at the school grounds.

I knew them. All of them. They were precious to me in my previous life, even more precious in this current life.

As strange as it may sound, I had attended this school as a second year student...in my previous life. Unbelievable isn't it?

Actually it is the truth. It's been ten years since I was reborn to the time when I was five years old. I can still remember it clearly my final moments before my current predicament. I remembered fighting the Devourer of Worlds and its armies while protecting an undeveloped universe and died in battle.

The moment I opened my eyes, I was sent back in time.

Thanks to the power of Space and Time Gems that I've got another chance, another shot in life. A chance to rewrite history and avoid this world's impending doom.

The creators of Space and Time Gems are unknown but what I do know is that these highly mysterious gems predates the entire universe or should I say multiverse itself.

I clearly remember, when I was fighting the Devourer of Worlds and its armies, my blood had thoroughly covered the two gemstones.

I knew that that it is must have been the work of the Space and Time Gems that brought me back to when I was only five. When I realized that I was sent back in time, I immediately searched for them but to my disappointment they were not with me.

As if they disappeared without a trace.

As I continued walking, I drifted into my distant memory.

When the Trihexa, the Beast of Apocalypse was revived by Rizevim Lucifer, the warriors of different forces that had overcome their differences gather in order to stop the destruction which will devour all.

The war was a complete mess. When everyone were fighting against Apophis, Azi Dahaka and the Trihexa, a rebellion erupted at the Bael Territory. In the end the enemies were defeated and the Trihexa was sealed again.

Yes the destruction of the world was halted but not without many sacrifices. Then an unexpected event happen. Out of nowhere the Devourer of Worlds came to the DxD world, my world, and began its "cleansing" of what he called the distorted portion of the universe after eradicating the ExE world in a whim.

In a sense, it was an extermination of all civilizations in the grandest scale.

We fought hard until our body couldn't move, until we exhausted every ounce of our energy to the last drop but we failed...

Even Ophis, Great Red, and Indra failed.

Even I failed.

At the aftermath of the battle, my world, my universe become a side dish for the Devourer of Worlds and I, the sole survivor of the DxD world managed to get out before the universe collapsed into oblivion and complete end. As years passed by, I traveled to many worlds, met many friends and enemies along the way who have different abilities and capabilities.

I also came across many mysterious things and two of those were the Space and Time Gems. If it wasn't for the gemstones, I wouldn't have been able to come back.

I was brought back to before the world's destruction. Before I was reincarnated as a Devil. Before my parents, friends and loved ones death in that one sided murder. Before Rias' death. Before each of my precious loved ones' death.

Now that I have given this chance, this time I won't fail.

This time I will protect them all!

"I'm home!"

I shout out as I entered my humble home.

"Welcome home, honey. So how's your day at school?"

Okaa-san greeted me as she walked in the living room. Seeing her figure, I give her a tight hug. Ever since I was reborn, I become so affectionate towards my parents. Guess that I learned a lesson in my previous life.

Treasure everything that is important to you, that is.

"Just like every normal day. By the way Okaa-san, I visited Kuoh Academy earlier."

"Oh? You've been visiting that school this days Ise. Are you sure you want to enter that school?"

"You know my answer Okaa-san. I'm very adamant to enter that school this coming school year."

The tuition fee for that school was very expensive and my parents knows that. They were reluctant at first in my choice but after explaining that as long as I can maintain my grades, the expenses would be cut off in minimum.

That aside I really wanted to go to that school. I wanted to meet all of them if not, most of them. I wanted to meet the people whom I bonded with in my previous life and I am willing to do that again.

"Don't worry honey, you know that your father and I will support you."

"Thanks Okaa-san. I'll be heading to my room now."

As soon as I entered my room, I started my daily routine by applying some bounded field using chakra around my comfort zone. Training that, is.

Ever since I went back in time, I trained myself to become stronger and powerful, the goal that I establish is that to surpassed my previous life's strength.

As I spent years in hidden training for this past ten years using the knowledge that I accumulated from my travels, they were many things that I've found out about myself as I progress.

First and foremost is that I don't have any talent in magic. Apparently my magic reserves is almost zero and despite the training that knowledge that I have gained from the Fairy World, I never progressed that much.

The reason that I could use magic in my previous life is that I was a Reincarnated Devil back then. An Ultimate-Class Devil to be exact.

Here am I hoping that I could use some Slaying Magic that I learned in this world, unfortunately this was not the case. So learning even the basic magic is out in the list.

The magic in that world was pretty powerful and useful though...

Second is that I can control chakra. My travels in the Shippuden World and befriending a Senjutsu master in the past did really helped me a lot in strengthening this kind of power which only the Youkai in this world can use.

I can't help but wonder what would their reaction would be when they saw a Human using Senjutsu.

Hohoho~

The third and the last thing that somehow horrified me up until now is the shocking revelation that I never saw coming.

I am not this generation's Sekiryuutei. That's right, I am not the current wielder of this generation's Boosted Gear. That fact and truth saddened me a bit.

Draig was my partner, a friend and a Dragon parent. Being the wielder of one of the thirteen Longinuses defined me in my previous life. Now that I think about it, the previous me was nothing but a weakling without Draig and the Boosted Gear.

It hurts knowing that but there's nothing that I can do about it but to accept that fact.

Whoever is the current wielder of the Boosted Gear, I wish that he or she won't turn out as perverted as me. Even if Draig never complained to me, I'm sure that he was not happy being called the Oppai Dragon Emperor and sharing it even though that title only referred to me due to my oppai loving tendencies.

Now let's get back to business.

After making sure that my room was dark, I grabbed a flashlight, turned it on and aimed its head directly at my left hand covered in a fluid-like energy. I am trying to mimic the properties of light using my aura.

What I'm doing is something that I learned while traveling across different multiverses. If the humans in one of those worlds can use their life force as a weapon, I think that the same applies in this world too.

Even without Draig and the Boosted Gear in me, I'm still determined to become the Crimson Dragon Emperor.

Devil, Dragonoid human or not.
