Esper Harem in the Apocalypse

"Jessica…?" Angelica muttered.

[Yes.]

"Why do you look like me?" she asked in a nervous tone.

[Because I am you.]

"...!"

[I was you before you died and became a ghost.]

"Wha…t? I don't understand. Why are you at Rudy's house, then? And… how are you alive if I am dead?"

[I am talking to you from 1999. I died in the year 2000, which is why I am still alive. And as for why I am at Rudy's house… it's my house too,] she responded with a shrug.

"What… do you mean? How could it be your house?"

[You must have seen the pictures in Rudy's phone of his one-year stay in 1989. Am I right?]

Angelica nodded a little without saying a word.

[There should be two… well, three girls. One of them is sis, one is me, and the third is Lilim.]

"I thought one was Rebecca."

[Yes, she is my sister.]

"..."

[That also means she is your sister too. And before you ask— no, Lilim isn't our sister.]

"You are lying! I am not Jessica! I am Angelica!" Angelica hissed.

[I never said you aren't. But Jessica and Angelica are the same. Just because you don't have your memories, that doesn't make you a different person.]

"Excuse me! I am dead!"

[That you are, but that's not the point of this conversation. We are contacting you for something important, something you would want to know.]

"I still don't believe a single word you say. You could be Rudy's enemy who has the power to change forms, and you took my form to deceive me."

[What would be the point of doing that? I will gain nothing by deceiving you. You can't even exist without Rudy.]

[Hey! That was mean!] the boy said to Jessica.

[Shut up. I don't care if it was mean or if she was hurt by the truth. She keeps asking stupid questions. And I am talking to my other self so I can talk to her however I want.]

Jessica looked at the camera and said, [I am done talking to you nicely. I should have known talking to your calmly wouldn't work since you are spoiled as fuck, just like me. You need to be yelled at and scolded.]

"No one scolds me!"

[Whatever. Now listen carefully, I have a task for you. I will give you—]

"I won't do anything you want, especially after you yelled at me. And I will tell Rudy about this, and he will find you and beat you!"

[No! You mustn't tell Rudy about any of this. He doesn't know it. He is not supposed to know it.]

"Oh, I will tell him everything. I will ruin whatever you are plotting." Angelica smirked and said, "That's what you get for messing with me. Now show your true self and reveal who you are."

[...]

"There is no way you are from 1999. How can someone from the past have a live video chat?"

[You yourself said that Rudy can do anything.]

"But 1999 has passed. It doesn't exist anymore."

[For you, yes. But for us, we are living in it.]

"How does that make any— wait…" Angelica looked at the boy and quoted, "Rudy can do it."

[...]

[....!]

"Does that mean that kid is Rudy?!" Angelica exclaimed in whispers.

The boy took off his mask and glared at Jessica.

[Well done. You had one job, which was to not reveal our identities, and you still couldn't do it. I know Angelica is not dumb, but you sure are one of the dumbest people I know.]

[How is it my fault? She tricked me into saying that. I wasn't prepared for her smart questions.]

"..."

SIGH!

The boy sighed and muttered, [What's done is done. There is no going back now.]

He looked at the camera and said, [Yes, I am Rudy.]

"Why… Why is your hair white?" she asked curiously.

[That's the first thing you ask, seriously?]

"How can you be Rudy? He is at the party."

[This is… 1999. Why would you even ask something so obvious,] he groaned.

"So… you are not my Rudy…?" she asked with a curious and confused look on her face.

[Ouch. That hurts. We both are the same.]

"No. For instance, I would believe that Jessica and I are the same, but I would never believe that you and Rudy are the same."

[That doesn't matter.]

"Are you the Rudy from this world before Rudy transmigrated to this world— in your body?"

[Yes, and no. Let me explain in the simplest words. This might get confusing, so I will refer to 2008's Rudy as your Rudy.]

"That's a fact."

[Your Rudy time traveled to 1989 and spent a year there. Then, he fought his greatest battle in space and died.]

"...!"

[He had lost his physical body and turned into pure energy, a part of the cosmos, to be one with the universe. When he died, he created a big bang that would have destroyed everything in existence.

His soul had shattered into billions of fragments and scattered all across the endless space— which would have created a new reality— a new universe. However, something strange happened, and the process was somehow reversed to the moment the big bang occurred.

His soul was divided into two equal pieces. One part returned to 2008— your Rudy— and continued living. While the other part was sent to the womb of a pregnant human woman in labor.

And that is me. I have all the memories, and so does Rudy. We both are part of one Rudy, living in different timelines at the same time. And we will merge again in 2008, which was also the moment he was transmigrated to my body.]
