Esper Harem in the Apocalypse

He looked at the time and muttered, "Rebecca is late. She usually wakes up at around the same time as me."

"It's a weekend," someone responded.

It was Rebecca.

"Don't suddenly do that. How did you even learn to be so quiet without making a faint noise that even my senses can't pick up?" he asked Rebecca.

"Maybe your powers aren't as great as you think."

"Ouch."

Rebecca looked at the ingredients and asked, "What are you making?"

"Eggs."

"I will help you!"

"No, you are going to brush your teeth and take a bath."

"..."

Rebecca reluctantly agreed and returned after twenty minutes. Of course, the breakfast was already prepared and served on the table.

"Jessica hasn't woken up yet?" Rebecca asked Rudy.

"Nope. Princess must be lost in the magic forest in her dream." He chuckled softly. "Go wake her up."

After waking Jessica up, they ate breakfast, but soon Lilim came downstairs while rubbing her eyes and stood before them.

"Oh, you are awake. Come here," Rudy called her.

Lilim walked to Rudy and sat on his lap.

"Do you want to eat?" he calmly asked.

Lilim shook her head and said, "I want to play."

"We will play later."

"..." For the first time, Rebecca was as confused as Jessica was.

It was natural for them to be baffled after seeing an unknown girl in their house that seemed so close to Rudy.

"Who is this girl?" Rebecca asked with an annoyed look on her face.

"Whoa!" Jessica pointed her finger at Lilim's forehead and said, "She has horns!"

"...!" It took a while for Rebecca to notice that Lilim had horns.

"I know you have a lot to ask, and I will explain things to you. But first, let's eat breakfast."

Rebecca had never eaten food so fast before in her life.

After breakfast, Rudy sat the girls down on the couch and stood in front of them.

"Rebecca, Jessica, this girl is Lilim. She is my… errr…. she is an important person to me, and she will be staying with us from now on. If you don't mind, that is."

"What if I mind?" Rebecca asked with a judging look on her face.

"Well, I will ask Elena to let her stay at her house."

Lilim jumped off the couch and hugged Rudy's leg tightly. She looked up and asked, "Daddy, who are they?"

"They are…uhm… treat them as your sisters."

"Sisters?"

"Yes."

Lilim turned to Jessica, who smiled at her in return, but when she looked at Rebecca, she found her glaring at her.

She pointed her finger at Rebecca and said, "This girl is scary!"

"I know. She becomes scary sometimes." Rudy patted Lilim and looked at Rebecca. "Be more friendly."

Rebecca glared at Rudy for a few seconds before letting out a weary sigh.

"Wow. You are becoming more and more… mature day by day."

'I was going to say more and more like mom. And yeah, she actually. The glare in her eyes just now is exactly the same as how mom glares at me when I do something she doesn't like.

I understand that she must have been shocked, surprised, even. But I cannot leave Lilim alone. She is as important to me as mom, Jessica, and Elena are.

"Rudy, Rudy!" Jessica also jumped from the couch and hugged Rudy, just like Lilim.

"What is it?" Rudy asked.

"Are we going out today?"

"Err… I have a date today with Elena. We haven't gone on any dates this month, so…" Rudy smiled awkwardly and said, "How about tomorrow?"

"I understand."

'Wow, I can't believe she actually agreed for once.'

Rudy turned to Rebecca and said, "Rebecca, will you take care of Lilim and Jessica for me?"

"What do I get in return?" Rebecca squinted her eyes and said, "Jessica always gets anything she wants by demanding, but I never get anything."

"What do you mean? I always gave you whatever you wanted. Didn't I? But if you feel like I have been neglecting you or treating you unfairly, you can always ask for anything," he said calmly.

"You can't give me what I want."

"Did you forget I have superpowers to do anything I want?" Rudy said with a smug face and asked, "Tell me, what is it that you desire?"

"..."

"Hmm? Go on. I don't want you complaining or holding a grudge against me for it."

"..tt…" Rebecca muttered something under her breath, and of course, Rudy heard it a little.

"Hmm? What was that?" Rudy asked.

"Attention! I want your attention!"

"Wha…t? What do you… mean? When have I ever not given you attention? My eyes are always on you when you are around."

"I think she wants to say that she also wants to hug you," Lilim quipped.

"Oh… I see…"

'She wants to be spoiled too. That's right, mom has always acted mature and has kept up this act all this time. She is only ten years old… I forget that sometimes.'

"Rebecca, when is your birthday?"

"After 2 days," she said without looking at Rudy.

'That's when I am supposed to be born, as my birthdate is also the same as hers.'

"Okay, Rebecca. On your birthday, I will be all yours. You can ask me anything, and I will do it for you. I won't pay attention to Lilim, Jessica, or even Elena."

"Will you do anything?" Rebecca asked curiously.

"Yes. Are you happy now?" he asked with a slight smile.

"You better not break your promise."

"I am a man of my word."

"So when are you going to explain her horns? Are they fake?"

Rudy tapped on Jessica and Lilim's heads and asked them to sit on the couch.

"It's going to be a long explanation. I will tell you everything about this world and the other worlds and races. Don't freak out, okay?"

"Okay!"

Even though they said that they freaked out the second Rudy told them that Lilim was a demon and Rias was a vampire.
