Reincarnation in DxD with wishes

For the past 3 days, we traveled through Romania with Rias, and I can say it's a pretty beautiful place. I've accumulated quite a lot of memories with Rias; I took her out for ice cream, and Romania was filled with monasteries. It's not good for demons like us, but going outside while the sun is shining feels good.

My aura color has turned golden, and it seems divine, all because of the influence of the sunshine.

when I use shadow energy my eyes turn purple, emitting a chilling aura.

Finally, the anticipated day arrived, and I was eager for the operation to begin.

Rias noticed I was preparing for something and asked where I was going. She wanted to come with me, but I declined, stating that I could accept her coming under one condition. She looked puzzled, so I began to explain to her about Zecht.

She realized I was about to do something dangerous, so I provided her with information about the individuals we would be encountering, Valerie and Gasper. We discussed Valerie, indicating that she was the one I was after, and started our conversation.

Rias: Ni-san, will everything be okay? Wouldn't it be better if we informed father?

Theo: Rias, next year, we'll be taking in two people for our peers, one of them will be from your nobility. Do we understand each other? And today, you'll see a different side of your brother. We'll be signing a magical contract; if you agree, I'll take you with me. These are the terms: you won't talk about what you see, you won't speak about my powers in any way, and you won't let Valerie join your nobility she is mine.

Zecht.

Theo: If you agree, concentrate your energy on the magic circle. Think carefully; if you don't abide by the agreement, you'll disappear.

Rias: I agree, she said.

Theo: And the deal is made. Rias, today you'll see the impressive and powerful side of your brother, get too close to me.

I pull Rias towards me, and she blushes. It's not my fault if Rias finds her brother so handsome.

I try to sense the castle's peak, but there's a barrier preventing teleportation against enemies. However, it can't stop me; I sense King Tepes sitting on his throne, surrounded by many guards.

Yes, this is going to be quite a show.

I teleport directly in front of the king's throne. All guards are surprised; they all reach for their weapons and a few move to attack.

I speak:

Theo: Anyone who moves without my permission will be dead.

As I say this, I release an aura of sunlight.

King Tepes: Have devils become so audacious? Do you seek war?

Theo: Oh, do you think you can cause trouble with your weak power?

King Tepes orders his soldiers to attack. Rias beside me is frightened, but I reassure her with a protective Limitless technique.

I draw Rias closer to me. Just as they're about to attack, I apply 200 times gravity to all of the 20 who were close, resulting in a gruesome sight.

Rias closes her eyes; I think I should have done the same.

Theo: You underestimated my warning, and now you've lost 20 of your men. If anyone else moves, I'll kill everyone in this room.

At that moment, I gesture towards the king, including him.

No one moves a muscle; they're all frozen because of the shimmering aura. There's a hidden massive deadly aura within it. The soldiers aren't moving like they're frozen.

I decide to turn the dead bodies into my soldiers.

Theo: Arise and serve me.

The 20 deceased soldiers become shadow soldiers.

Everyone in the room is shocked; their mouths nearly hit the floor. They witnessed me kill their comrades and turn them into my soldiers. When they see them rise and become my soldiers, they understand they shouldn't mess with someone like me.

The shadow soldiers kneel before me. One of them speaks: "We will serve you my lord as you wish."

I order them to enter my shadow, and they promptly obey.

I look at the king: "Now, shall we talk? If you're still silent to death, I can always assist you."

King Tepes: "Understood. How can we help you?"

Theo: "You know Valerie and Gasper Vlad are here in the dungeon. Hand them over, and I'll let you alive."

King Tepes: "Do you want those troublemakers? Take her and take Gasper, he's already caused us enough harm."

I make the king stand up and face me. Then I apply 10 times gravity against him; he falls to the ground, now in a begging position. I place my foot on his face; he can't retaliate.

Theo: "Show respect to a true king next time, you mongrel. If you dare speak of what happened here to anyone, I'll erase the vampire race from this world. Do you understand?"

The king struggles to nod his head; he's been traumatized by Theo's actions and decides he doesn't want to see him again.

At that moment, while Rias and Theo are on their way to the dungeon, Rias speaks:

Rias: "Brother, you were so cool back there. I didn't know you were so powerful."

Theo: "Rias, remember not to tell anyone what you saw."

Rias: "I won't forget, brother."

As they enter the dungeon, they find Gasper and Valerie. Both are surprised, then they see me and I approach them with a warm smile and a sun-like aura, this time emitting a comforting aura that feels human. I extend my hand to Valerie.

Theo: "Hello, Valerie. I'm Theo. I've come to rescue you from this misery-filled life."

Gasper watches from the side.

Valerie: "I have nothing to offer you. Why would you help me when I have neither money nor beauty?"

Theo: "There's no need for many reasons to rescue such a beautiful girl from such a life."

At that moment, it seems like Rias is emitting a deadly aura, but she tries not to be noticed, but I've already seen her.

Valerie starts crying, asking why repeatedly. I embrace her and comfort her, then stand up and make an offer to both Gasper and Valerie.

Theo: "Valerie and Gasper, I invite both of you to become my peers. If you accept, you'll be important to me. The red-haired girl you saw beside me is my sister. Gasper, if you want, you can join her as a peerage. Don't be afraid of the forbidden ballor, I'll teach you how to use it properly. Valerie, if you want, you can join my peers and always be with me."

Gasper and Valerie finally agree, and take them to the house
