Reincarnation in DxD with wishes

CHAPTER 1

[Hello, I'm your regular writer, and this is my first work. Please comment to correct my mistakes. Mc is so overpowered and he sometimes acts stupid. if you didn't love the story don't read it.]

Hmm, where is this? Why is everywhere dark? Where am I? Have I been kidnapped? Then I remember, there is no reason for me to be kidnapped. If my family knew I was kidnapped, they wouldn't care. So, I don't think they would waste their time with someone like me.

While I'm thinking to myself, I hear a voice.

ROB: You finally woke up.

MC: Hello, what am I doing in this black void? Are you God? Then, is there heaven or hell? Damn, I guess I'm going to hell.

ROB: Relax, my child, they exist, but I came to you with an offer.

MC: Even though you seem very suspicious, what is your offer?

ROB: Son, you're lucky. Normally, you should have gone to hell, but you were sent to me by the Great Truck Kun.

MC: I understand, it's a cliché reincarnation story. So, will I have wishes? Or will I keep my memory? Can I choose my appearance?

ROB: Yes, you can. You have three wish rights, and if you try to make infinite wishes, I'll send you to "Boku no Pico". Don't try to fool me, understood, son?

MC: I definitely wouldn't do such a thing.

ROB: Anyway, have you chosen your world?

MC: Yes, I want to go to "High School DxD".

ROB: You know, I won't question. do whatever you want.

MC: You don't even need to say it, I'll do it.

ROB: Tell me your wishes, let's finish this quickly.

MC: Okay then, firstly, the essence of the void.

ROB: Accepted. This essence removes the limit of your potential, but it doesn't increase your learning speed. As you educate yourself over time, your ability will come with you.

MC: Secondly, space-time manipulation.

ROB: Accepted.

MC: I want to store everything used in all anime, such as fighting styles, magic, etc., in a place in my brain like a palace, and I want the magic to change according to the magic system in "High School DxD".

ROB: Accepted. You used your wishes wisely, son.

MC: Thank you.

ROB: So, who and how do you want to look?

MC: I want to be born as Rias's twin brother.

ROB: You don't need to specify that you're a boy.

MC: You never know, I've read so many gender-bender stories. All of them, especially when a man is reincarnated as a woman, think about it, what will you do? Will you enter Issei's harem?

ROB: [Oops, I missed my chance.] Alright, how do you want to look?

MC: Red hair, obviously, and a handsome, masculine face. I don't need anything else.

ROB: Okay, then everything's settled. See you then and have happiness in your life.

Hmm, as I open my eyes again, I feel covered in liquid and realize I'm in my mother's womb because there's another baby next to me, and I'm not stupid to not realize this while my memories are with me. Anyway, it seems we have plenty of time to wait, so why not try something?

As I think about these things, I get tired, then I fall asleep again. When I wake up, I'm already thinking about what I can do in the womb; after all, I still feel like I have time to be born. Then I remember I'm a noble demon. Usually, noble demons have more demonic energy, when Sirzech was born, he had ultimate class reserves, so I try not to waste too much time and try to meditate on whether I have demonic energy. Then I feel the energy in my very small body and look for it in my mother's body, and yes, I'm trying to mimic her absorbing demonic energy, and I'm taking a small part of it from her. Don't be offended, Mother, everything's for power.

4 months later

It seems like my birthtime has finally come. So far, I haven't done anything other than accumulating demonic energy in my body, my friend. I still have a lot of time, I'm not a wuxia hero, creating a technique that will challenge heaven while in the womb. I hear shouts outside, "Ha, go to the white light," and I'm getting closer and closer, and yes, I'm finally born! And Rias followed after me.

And I started crying, why you ask, my friend because I don't want to get into more trouble just because I didn't cry.

Zeoticus: Yes, our twins were born. Both of them have red hair, and both of them have high energy reserves, but the boy's reserves are even higher.

Zeoticus lifted me and said, "I decide the boy's name, and you'll decide the girl's name, Venelena."

Venelena: Okay, then the girl's name will be Rias.

Zeoticus: Then yours will be Theo.

Watching from the side, Sirzech picked up Rias and was already smiling; he was probably starting to become a sis-con already.

Grayfia has a slight smirk on her face, I never understand why they're so obsessed with the servant role.
