1 Killing A Threat To The World Is A Rational Decision

"Are you happy now? You stopped me from restarting this world. You don't have to blame yourself since it is the most rational decision according to yourself."

A 17-year-old girl wearing a white robe says to me as she lies on the ground. Her long white hair lay on the ground like flowing waterfalls and her two eyes that have a clock symbol starts to rotate.

I hold a sharp metal knife in my right hand and direct it towards the chest of the white-haired girl.

"When are you going to end my life? Are you hesitating? Just so you know, It is only a matter of time before I can restart the world."

The white-haired girl reminds me as the clock symbol on her eyes begins to glow.

"Don't worry. I will fulfill my promise. Both of us will remain as history in this world. Killing you who threatens the safety of the world is the most rational thing to do. Even if I love you..."

I say and look at the white-haired girl while raising my hand that holds the knife.

"...My dear little sister. I am a failure as your brother. But even so, sacrificing your life to save billions of life is the most rational thing to do. Farewell..."

I mumble as I look at my little sister one last time and I didn't even notice that my actions cause drops of tears to trickle down from my eyes.

"Time Reversa-"

"Skill Activation + 60 seconds!"

I tap my left hand on my little sister's eye and lengthen the time to activate her Time Reversal.

I stab the knife in my right hand into the heart of the white-haired girl. Red liquid gushes out from the wound on her chest as I pull out my knife and throw it on my side.

"*cough* Even if... you kill me, I will still lo... ve you..."

The white-haired girl coughs out blood while telling me her last words in difficulty.

"I love you too. Don't worry, I will accompany you soon to the other world."

I assure the white-haired girl as I kiss her forehead. The white-haired girl smiles one last time before she breathes her last breath.

I stand up from the ground and I check my surroundings.

"Did you finally kill the witch of time? I am surprised! For a villain, you did something heroic!"

A man wearing a black robe and a white mask covering his face teleports in front of me.

"You will be more surprised if you know that you are going to die."

I threaten the masked man as I divided his clone by zero.

"I am the only one who can insult my little sister. You have no right to call her a witch."

"I didn't kill her to save you ungrateful and sinful humans. I only killed her because it is the most rational thing to do."

I declare to a live news helicopter flying in the sky as I point my finger towards it.

"Helicopter Gravity x 1000!"

I apply a thousand times gravity into the live news helicopter and in just a second, the helicopter slams into the ground. The helicopter then explodes after it was slammed into the ground.

"Killing scums of society is the most rational thing to do."

I mutter to myself as I slash my hand in front of me. A crack in space appears in front of me and I enter. Dividing distance by zero results in attaining Nigh Omnipresence. I used Nigh Omnipresence to create a portal that leads to another world.

I fulfill my promise to my little sister since it is the most rational thing to do. Our promise was for me to accompany her to another world. My little sister should have arrived at the world of the dead and I will go to another world.

I know that by killing my little sister even though I loved her than this wretched world will leave a scar in my heart and haunt me in the future. But, calming myself and praying for my sister's wellbeing in the world of the dead is the most rational thing to do.

Overthinking what has been done will bear no fruit and it is irrational.

As I immerse myself with my thoughts, I bright light blinds me. After my eyes get used to the light, I see a huge dragon heading towards me.
