Reincarnation in DxD with wishes

Scathach decided not to rest until she reached the 200th floor, thus continuing their dungeon descent. She wanted to see Theo's face when they reached the 200th floor. 

During their ascent, Scathach encountered formidable foes. For instance, on the 160th floor, she clashed with Godfrey using a spear. On the 170th floor, they fought hand in hand with Dante from DMC5. On the 180th floor, she crossed swords with Kizaru from One Piece. On the 190th floor, she battled Berserker Hercules, which was quite a challenge.

Today, they finally reached the 200th floor. This process took a total of 2 years. Scathach and Theo are 18 years old. During these 2 years, Scathach behaved strangely; she would embrace Theo for long periods or secretly observe him while he showered. The truth was, Scathach had turned into a pervert, which was frightening.

Scathach was excited today because if she won the battle, Theo would allow her to seek revenge, which was thrilling. After entering the floor, Theo left Scathach alone and teleported somewhere else, returning with a spear. He handed the spear to Scathach, and all the information about the spear flooded her mind. Yes, this spear was Gae Bolg.

After giving her the spear, Theo, slightly teary-eyed, said, "This is your gift for reaching the 200th floor. This weapon won't break and will always be by your side. This is my first gift. My second gift is that since I know my identity, I'll grant you as many questions as you want."

Theo puts his hand on his forehead. "Damn, I feel old. My dear , you were just a little girl yesterday. Children really grow up fast."

When Scathach hears this, she smiles even more. They progress to the 200th floor, where they encounter an empty landscape. This time, Scathach will fight with the spear given by Theo.

As they continue forward, they come across a man lying on the ground, seemingly missing half of his body or wounded, which would be more accurate. When the man senses Scathach's presence, he stands up with his hammer in hand. There's a strange golden rune in his wound.

The man's identity is Radagon of the Golden Order, quite a bulky figure.

Without waiting, Radagon swings his hammer at Scathach, who dodges it, causing the hammer to strike the ground, creating a 50-meter-deep pit. Scathach's eyes widen, knowing that one mistake could mean her death. She immediately launches a counterattack, and her spear pierces Radagon, but it seems like nothing happened. Radagon, like a zombie, lifts his leg as Scathach tries to withdraw her spear. With a golden light shining, he slams his foot on the ground, and Scathach flies with her spear, sustaining severe injuries, which she didn't expect. Then, without hesitation, Scathach throws her spear at Radagon. The spear goes through Radagon's chest, and with a move taught by Theo, she pulls the spear back, slicing through Radagon's head as he wasn't expecting it. Radagon's body falls to the ground. As Scathach turns her back, the rune inside Radagon fades, and a strange creature emerges from within – the Elden Beast.

Seeing this, Scathach curses Theo again, then looks at the spear he gave her and then at the creature. She then screams and throws the spear at the beast.

"GAE BOLG!"

A purple light emits from the spear, directly hitting the heart of the creature, and the Elden Beast perishes. Scathach falls to the ground because she had put all her energy and endurance into that attack to finish it in one go.

Then Theo appears, lifting Scathach's unconscious body, and they return home after removing her wounds and cleaning her up. He puts her on the bed, and just as he's about to leave, Scathach grabs his hand and, in a faint voice, says, "Please don't leave me alone."

Theo feels sorry upon hearing this and lies down next to Scathach. Usually, Scathach isn't cautious when Theo sleeps because every night she comes to him and sleeps beside him, so naturally, he doesn't always resist her

Then Theo hugged Scathach and fell asleep. Time passed, and slowly morning arrived. Before Theo woke up, he noticed that his upper clothes had been removed, and they were wet. Strangely, ropes were tied around his arms and legs, and Scathach was on top of him, her eyes filled with madness for some reason. Without saying anything, Scathach kissed Theo on the lips and clumsily entwined her tongue inside his mouth. Seeing this, Theo did the same, surprising Scathach, but they continued for a full 3 minutes.

Then Theo got up as if the ropes were gone and put Scathach back on the bed. Then, with a sad tone, Theo said, "I'm sorry, but I can't do this now. I have a wife, and this would be a betrayal to her. I appreciate your feelings, but I can't be with you right now."

Upon hearing this, tears welled up in Scathach's eyes, and she spoke in a tearful voice, "Who is that bitch, who took my dad away from me? My father belongs to me alone, always mine."

Then Theo realized that Scathach's sanity had deteriorated. He calmed her down and then sat with her at the table.

Scathach immediately starts asking questions: "what is your name and age?."

Theo: "My name is Theo. I won't mention my surname. I'm 18 years old, but age doesn't matter to me."

Scathach, in an angry tone: "Damn, all this time I was calling someone at my age 'dad' because of your unchanged appearance. Well, what is your wife identity?"

Theo: "She's a dragon. I won't disclose her identity."

Scathach: "Okay, one last question. Are you going to leave me?"

Theo remains silent, and upon this, Scathach starts crying, runs out, and takes the spear with her, most likely to release her anger on her mother. She already had enough power to take revenge on the 150th floor, but Theo made sure she reached the 200th floor so that Scathach eill bully her mother with her current strength.

After these events, Theo doesn't say anything and writes a letter on a piece of paper, then returns to his time.
