Reincarnation in DxD with wishes

After 11 months...

Finally, tonight marks our last day in the human world. During this time, much has happened. Theo has wandered the streets, and killed numerous stray devils, almost becoming the nightmare of the strays in Japan. And all these strays have become Theo's shadow soldiers. There are at least 1000 devils in the army.

During this time, he didn't just focus on the strays; he also gave importance to Rias, Valerie, and Gasper's training. Gasper's muscles are now more defined. I lifted his hair and told him to leave it like that. Of course, I didn't forget the deal with Azazel. The deal was completed, but I'm still wandering in Grigori. Frankly, I saw Raynare here.

*Flashback*

While wandering in Grigori, I saw Raynare, Kalawarner, and Mittelt together. At that moment, I looked at Raynare. I don't know why she's wearing that dress. Raynare looked at me and yelled:

Raynare: "What are you looking at, devil boy? Are you seeking your deaths?"

At that moment, Kalawarner tries to stop her because she sees how powerful I am. Theo turns towards her, then applies five times gravity to Raynare. Raynare collapses to her knees. She's weak. I don't understand how she can't bear this much. Then I walk towards her, and give a light punch to her stomach, but then a gust of wind comes out. That was a weak punch from me. She can't bear it and vomits. Then I lean close to her ear and say:

Theo: "Do you know what they're saying about me underground? The demon king, do you want to see if I deserve this title or not?" Then I forcibly pull out her wings. It's a horrifying scene.

After that, Theo leaves as if nothing happened. Kalawarner and Mittelt are still frozen. It was the most terrifying sight of their lives, and Raynare was lying on the ground, her breath weak.

*End of Flashback*

It was a good encounter. I did it to see how she would react when she saw me in Canon, and it was fun. Now, Azazel has kept his promise in the deal we made about the Shinto gods. He gave me a couple of advice, and I decided to apply them. Theo didn't forget to return to the Gremorys every month and report. And he's preparing for another ritual. To complete the ritual, he'll have to make a trip to Uruk. Time will tell us what will happen.

Then we all return underground and are greeted warmly. My mother and father are waiting for us there. Sirzech and Grayfia are there too.

All of them: "Welcome home!"

This scene makes me laugh. Then my father comes to me.

Zeoticus: "Welcome home, my son. I hope you enjoyed the human world because going there is forbidden for a long time. At least until you're 11."

Theo: "But why, Dad?"

Zeoticus: "Do you know the trouble you've caused? It doesn't matter. You should thank your brother. He dealt with most of it."

Sirzech: "Father, don't push him so hard. Brother, you've grown stronger. I feel like we're on the same level. It's abnormal for your age, but it doesn't matter. After all, you're from our family. If you weren't a Gremory, I wouldn't have let you grow up. You know what they say, you have to crush the snake's head when it's small."

Venelena: "Okay, that's enough talking. I miss my son. We'll talk about these later."

My mother comes and hugs me, making me feel very soft.

Venelena: "Theo-kun, don't forget about Rias-chan. You'll soon receive your evil pieces. And Theo, you'll be the real ace. Your name is known in the underworld, but your appearance isn't well-known."

Theo: "Don't worry, Mom. Everyone will know me, and I'll make such an entrance that no one will forget me."
