Esper Harem in the Apocalypse

"Excuse me, I am biologically older than you."

"No, you are not. Eric and Erika are younger than me and you were born even after them." Rudy turned to Elena. "What is she talking about?"

"She just wants to assert some kind of superiority over you. Since she couldn't say she is mentally older than you, she chose the other one. But… she is kind of… well, not older than you, but… uhh…"

Elena glanced at Yelena before turning to Rudy and saying, "She started having her red days when she was nine. And she was the tallest girl in her class."

"Oh, so her growth hormones are on steroids…"

"And she is my sister, so you know she was born naturally smart. Unlike me, she completed her bachelors at the age of twelve, and she is currently an online celebrity while her day job is… a scientist."

"And more," Yelena quipped and continued,

"I have been to various ancient sites and explored the ancient civilization. When I was a child, it didn't pique my interest, but after listening to your stories from sis, it became a daily routine and I wanted to explore what was lost with the passage of time.

I will admit, I don't regret making that choice. My research projects were terminated by the government for no apparent cause and I was warned by my higher ups to cease the projects. Otherwise, I would have lost my license."

"Yeah, there are always things they don't want us to find." Rudy nodded with a playful smile. "However, I must admire your work. I would love to see your research and share knowledge with you one day."

"You can mind my research and case studies on the internet. It's available for everyone, for free."

"For free? Did your company allow you to do that?"

"They didn't at first, but then sis bought the company."

"..."

Rudy looked at Elena with a black expression on his face, but his face said 'I should have seen that coming'.

"What? I just wanted to help my little sister," she shrugged casually.

"My motive wasn't to make money out of my research. I was born into an extremely wealthy family, and an even wealthier sister who could buy anything in the world."

"Of course, I wasn't dependent on any of them," she immediately added.

"I believe the research and the case studies about non-humans and their civilization have been kept secret, hmm?"

"Obviously. But throughout history, some of them were captured, and they were taken to a facility where they were experimented on. You might know that area as Area 69."

'Most likely, the supergene experiment was conducted there too. And the genes installed in the human bodies were extracted from the captured and imprisoned non-humans.I think you should take a look at

Everything makes sense now. Little by little, the mystery is revealing itself. I wouldn't have found that out if it wasn't for Yelena, who became interested because of Elena, whom I revealed everything about to me in 1989.

Had I not been in 1989, so many things would have been left unanswered. I used to think the only purpose of me being sent in 1989 was to raise Rebecca, Lilim, and Jessica… also to impregnate Elena so she could give birth to Eric and Elena.

However, there were many other things. I met Rias and Nyxia in that timeline. I do admit that everything that happens happens for a reason. But who is controlling the reason?

I know that an external force had sent me into the past. It was because of that I died fighting Asura and half of my soul was reincarnated into the body I am in today.'

It wasn't a mystery that could be solved in one sitting by simply assuming things and jumping to conclusions.

"Still, to think that you would be my substitute in my absence," Rudy remarked with a chuckle. "Considering how much you hate my presence."

"For your information, I am not doing this for you. I am doing this for sis! I live in this world and I don't want it to be invaded or attacked by other races, and therefore I will do whatever it takes to prevent that from happening.

But you are right about me hating you. I hate your character as a person, it's nothing personal. I admire your knowledge, strength, courage, and the suffering you have been through, though."

"Now that I know everything and Elena has told me what she wanted to inform me, you no longer have to be the ambassador. You can quit the job. I will take over. However, if you want to continue voluntarily, I won't stop you."

He shot a charming smile at her and continued, "Keep doing what you are doing. I just watched a few of your case studies and I am impressed by your work. You did great."

Yelena's face flushed a bit, but she kept herself composed.

Elena shot a glance at Rudy and said, "Stop hitting on my sister. And if you like her, at least don't flirt with her in front of me."

"What the hell do you mean by that?" Rudy furrowed his brows. "When did I try anything?"

"Ask Rebecca if you think I am overreacting."

Rudy turned to Rebecca with a confused look on his face and asked, "What is she talking about?"

Rebecca shook her head and refused to speak.

"I know that wasn't your intention, and you meant nothing by your statement, but you made Yelena's heart flutter for a second," Elena commented.

"How?! She just admitted in front of you all that she hates my gut."

"Even so, you managed to catch her off guard."

"Are you teasing me right now?"

"Why don't you ask her?" Elena pointed her gaze at Yelena. "She is always honest and will never lie."
