Entering The World Of High School DxD

{Pov: Kuroka}

My name is Kuroka just Kuroka, I'm a Nekoshou who was reincarnated as a devil of the Naberius branch family with my little sister Shirone. Nekoshou have no concept of family names so us sister don't have them neither did our mother.

From what I can remember from my mother was that she was a sweet, caring, and thoughtful lady. She always treated both Shirone and I with love an affection, the only fault I could point out was that in the face of love she was a clueless and clumsy woman.

Of the information, she gave me on my father it always seemed so aggregated and made up. When I asked why we couldn't see him she always came up with a 'noble' reason for not being with us and I knew that it was only a one-sided love.

It wasn't until I turn 9 and Shirone turned 5 did Mother start to look for father. After 2 months of searching, she finally brought us before him. He was a plain man, he wore a white lab coat, had square glasses, an unshaved beard, and eyes full of uninterest. {A/N: Just made this up don't quote me on this.}

Just looking at him I couldn't find out why mother chose him, but he was my father though unwilling I had to treat him with respect. He seemed to work for the house of Naberius which surprised me.

He was human and Naberius was a devil, by common sense they shouldn't be together I couldn't understand. Naberius-sama took interest in Shirone and me, he said we had potential, and wanted us to be part of his peerage.

When father said a few words mother instantly agreed. We could do nothing about it, 3 months after we moved into the Naberius Manor mother died. She kept this hidden from us and said that was why she took us to meet our father.

As for the man in question, he took part in the funeral but left soon after not even looking into the casket. I had had enough, I originally put up with him because of my mother but now I simply wanted to leave.

But I didn't have the strength to do so. Shirone was a timid little girl, and I was only slightly stronger than her. Even if we could escape we'd never survive as strays. While looking at my crying sister I promised myself to get stronger, I didn't want her to lose herself into becoming strong and started to work hard for both of us.

1 year passed and I made some headway in my senjutsu but it wasn't enough. Shirone also tried using senjutsu but I told her to take her time with it while I secretly pushed myself harder than ever.

A month after I turned 10 I was called before father who told me I'd have to participate in some experiments to help strengthen myself for Naberius-sama as compensation for taking up two bishop pieces. I could only agree helplessly on the outside while determined to use this as an opportunity to get stronger and escape. Naberius-sama wasn't that strong and if I could overpower him I could get away. All I needed was time.

I started meeting Shirone less often because the experiments took a big toll on me and I didn't want her to see me suffer. However, I couldn't forget the look of delight she had when she saw me after going missing for a week.

Kuroka - [Oh Shirone please just endure a little longer I'll take us away from here as soon as I can.]

I could see from a glance that they haven't treated her badly as per our agreement, but her being separated from me caused her a lot of anxiety but there was nothing I could do.

2 years passed and I turned 12, and my will was slowly grinding down. With each session, I try to take in as much of the foreign energy as I can but it always seems to escape my body soon after. The action is extremely painful not for my body but for my soul. To make up for it I try to heal my soul with senjutsu it works and I slowly start to get stronger.

Another year passed and my hatred for my father and Naberius grew. I discovered that they were using me as a genuine pig for their super devil creation project. This whole time they believed that they were the reason I was getting stronger but that was only half right. The reason I was getting stronger was that I was healing my soul after they damaged it.

In the past few months, they did the same process on other test subjects only for them to all die. I could care less until the man who helped birth me said:

Dead beat dad - Maybe there's a special variable in nekoshou that is compatible with our experiment.

Trash of a master - That could be it!! I'll send a small army to their village to capture as many as we can get. If they don't want to agree we'll just kill them.

Dead beat dad - Perfect for now I'll start work on the white cat, someone prep black cat for her daily session.

They wanted to harm not only my own people but even my sister!!!! The promised me they wouldn't try anything on her!!

Enraged and infuriated I went mad I kicked and thrashed but was later sedated with drugs.

Dead beat dad - Could this be a side effect of the treatment? Hey, when you start the preparation make sure to bind her to the table okay make it's strong too.

And like that, I lost consciousness. When I woke up a few hours have passed and the lab was in a frenzy. I learned two bits of information in that short period of time. 1) A large dispatch force of the Naberius House's forces was closing in on the Nekoshou Village and 2) A strange phenomenon occurred in the forest west of the manor.

Naberius and the man we thinking that it could help with the experiment so they sent a small despatch force to retrieve it.

While everything happened I noticed a small scalpel knife that was within reach on the table next to me. My hands were bound but my tall wasn't, it may have become weak with the sedatives but if I could just get my hands on it I could escape and kill everyone here. I don't know why but I felt I could do it if it's me right now.

My tail was able to grab the knife but kept dropping it when I tried to left it. But this didn't stop me, with each fall my emotions turned colder and I was slowly letting my anger take over me.

Kuroka - [Just a little more, just a little more and I can ki---]

*BOOM*

*BOOM*

2 loud explosions went off by the entrance of the lab destroying the door. The shock from the blast was able to bring my thoughts back to normal and I was shocked to realize what I was planning to do. If I did any of that not only would I put myself in immediate danger but I'd also endanger Shirone if I brought her with me.

Turning my head to look at the door I saw something that caused my eyes to widen.

At the door there was a youth, he looked to be around my age height wise but deep in my heart, I felt he was younger than me. He was dressed in blue pants, a grey shirt, and a loss black cloth jacket. His light brown hair was long, and his magenta eyes looked like they were glowing.

His face looked somewhat handsome as he wasn't finished growing yet but, I felt he would be really handsome in the future. He had an otherworldly aura around him that seemed to draw my intrigue towards him.

In his hands were two black guns that had smoke coming out of their barrels. Suddenly a lump started to form from the back of his jacket and a small figure feel down from his back.

... It was Shirone

She surveys the area before she saw me and ran up to me who was in a sorry state. Once she was right beside me she took out the needles in my body and started to work on my restrains with teary eyes.

Moving my sight from Shirone I looked at the boy who brought her here I saw him killing the scientist in the lab without a second thought. When everyone but 5 of them have died the lab went quiet other than the low grunts of Shirone trying to free me.

While holding everyone at gunpoint he made his way toward us and with the wave of his hand cut the restraints. I still couldn't move but it felt nice to be free. Slowly putting down one gun he placed his palm on my exposed back.

Suddenly I felt a wave of life force enter my body slowly giving me back control as well as closing up all the puncture wounds on me.

??? - Don't worry it's going to be alright.

Showing my calming smile I didn't know why but I felt relieved beyond relief and tears wouldn't stop falling from my eyes.

Kuroka - Thank you!
