(POV-Shira)
"I borrowed your AI- Aria's, help to analyze her entire ship."(Shin)
Onii-chan found a ridiculous way to send your consciousness to the past or future- time leap- without breaking the fabric of fate.
"That machine can literally scan the soul itself. I decided to name it Soul Translator. If used correctly, you can digitalize any lifeform. Immortality is another way entirely though. You can call it 4th generation VR console I guess."(Shin)
"That's absurd!!"(Shira)
My mother indeed made a blueprint for the prototype for first generation full dive VR. But this one in front of us is advance by 50-75 years.
"... Mirai's father is way too amazing."(Shira)
"Yeah. I already reverse engineer and created the theorem. That where I found out that time leap is possible."(Shin)
I groaned seeing the formula in the board.
"As I've thought... It is you that inherited mom's genius."(Shira)
"While you inherited dad's ridiculous brain skills."(Shin)
He shrugged his shoulders and asked my help to create the time leap machine.
"Well... I guess we will help Mirai-chan save her world?"(Shira)
"!!!"(Mirai)
"Yes. I already found a way to avert the disaster coming to this world."(Shin)
We start creating the device while we teach her the necessary knowledge she needed to convey to her father and mother.
===============
(POV-Mirai)
I lay at the machine that is akin to metal coffin while the siblings looked at me with worried expressions. I just smile wistfully seeing that they are truly kind.
"Will I remember you all?"(Mirai)
"Yes. You have my protection so all your memories will be remembered."(Shin)
"I see. Please start the sequence."(Mirai)
I close my eyes and when I heard the start, I opened my eyes again.
"Congratulations!!! It's a girl!!"
I trained myself and prevented my mother's death. I told them the virtual network the 2 created for me. They verified all the data on that website.
"... So you really came from the future?"(Seiji)
"Yes. I still remember mom dying, you seeing me of, moon falling on earth. I am gifted with perfect memory ability that I even think it is nuisance for me. But now, I'm thankful. o can use it to save my family."(Mirai)
"Who are they? Those kids that saved you?"(Seina)
"They said they are travelers that cross multiverse."(Mirai)
"... You believed that?"(Seina)
"I mastered lie detection technique."(Mirai)
I smile wryly. We start collecting all powers of mankind and unify it to save the world.
=============================
The world is saved, We managed to build the Dyson Sphere as proof us becoming the Type 2 Civilization. We also managed to terraform Venus and colonized Mars and Earth's moon.
"I'm 15 already. You promised to take me right?"(Mirai)
I'm sitting at the edge of the rooftop. I already have a brother that will inherit the company. And I graduated with 25 Ph.D. to numerous universities around the world.
"Well... I guess we have to let our families talk with each other first."(Shin)
He appeared sitting besides me. I smile and stand u-
"Woah!! Hold your horses! You almost fell!!"(Shin)
He embraced me tightly on his arms.
"What took you so long?"(Mirai)
"Some troubles on our world. Nothing much serious."(Shin)
We decided to go to my home and introduce him to my family.
