Reincarnation in DxD with wishes

The fact that I no longer have to train brings me joy. I've been training since childhood, striving to become unstoppable. There's still a long way ahead of me.

Today, Grayfia will return to Sirzech, and I'll miss her.

While we were at the table, my father began to speak:

Zeoticus: "Son, I'm proud of you, honestly. I didn't expect this much, especially knowing you're that strong. Everyone has their secrets, and if you don't want to share yours, it's okay."

Theo: "Thank you, Dad, for respecting my secrets."

Zeoticus: "Always, son. One thing I know for sure is that you love your family. We love you too, and that's why I support you. Your name has started to be heard in the underworld. Before, even when you were showing your gratitude and throwing punches, they called you 'crazy'. After what you've done now and the fight between you and Grayfia, your nickname is 'Demon King'."

Theo: "Although I'm curious about where this nickname came from, I accept it because I like it."

Zeoticus: "I'm proud of you. At first, when I thought you were going to quit training, I was upset, but I'm proud of you for coming back and improving yourself. If you and Rias want something, you can tell me."

Rias: "Hmm, as long as Ni-san is with me, I don't want anything. I just want to play with him more."

And quietly, she says, "If possible, forever."

she can't hide this from me anymore because as I've developed, my senses are at a crazy level, and now I'm aware that I affect Rias.

Venelana: "Rias, you've become so brave lately to Theo-kun. I wonder what Theo has done to Rias, I'm very curious."

Zeoticus: "Alright, I'll give you and your brother more freedom. So, Theo, what do you want?"

Theo: "If possible, I want to go from the underworld to the human world. I just want a one-year leave."

Rias interrupts:

Rias: "What, are you going to leave me, ni-san? Are you going to leave me alone? Won't you miss me?"

My father coughs.

Zeoticus: "Now, this is not impossible, but how long do you want to stay? After all, next year you and Rias will both take your Peerages, and under certain conditions, this is possible. Your brother wants you, so you have to take him with you. You must stay here and report for three days every month. If you do these, I'll send you, and money is not a problem, don't worry about that. If you accept these terms, you can leave."

Theo: "I accept, dad. Even if you hadn't said it, I wouldn't leave Rias. Even though she can be very annoying sometimes, how could I leave my little sister alone?"

I winked at Rias at that moment, and she turned her head.

Venelana: "I hope you don't forget your mother, son. Your mother still feels lonely without you, I remember when you were a baby, Theo-kun, and now you're leaving your mother as you grow up."

Theo: "Mom, you're talking as if I'm never coming back. I'll visit you every month, please don't make me sad."

Zeoticus: "Enough of this drama, your request for a one-year leave is granted. After that, next year, you'll come and take your Peers stones."

Theo and Rias: "Okay, dad."

The next day, we started packing our things. The first destination was clear, I couldn't leave Valerie there, I had to take her with me. It would be foolish to leave someone who possesses the Sephirot Grail.

We're heading to Romania, to a hotel. My father had rented a house for us there, and we're settling in with our belongings. And yes, now I think it's time to gather shadow soldiers for the vampires. I'm preparing some silver for vampires, whatever they need against vampires, I'm getting it.

I'm exploring Romania with space manipulation, feeling everything about it. I've found the location of the Tepes family. The operation will start in 3 days.
