13: OverPowered

"H-help" a swordsman ran in fear as he shouted fearfully, his voice only causing echo's throughout the forest.

Behind him was a tall demon with long limbs, nearly like an ape, it was extremely built and terrifying.

"Hehe, another human, more and more, I want more, stronger!!" The demon shouted hysterically as it roared, its thick arms shattering a tree trunk with a smash.

"Come here" it roared as it reached out, grabbing towards the fleeing human.

A wild scene happened after that, it didn't feel flesh, instead it's huge fist actually landed on... a f*cking sword?

"Not so fast" itsuki said with a smile as he watched the person disappear after being scared shitless.

"And who are you?" The demon said with a shocked expression, it's dusting tongue only made it creeper as it drooled at the sight of human flesh.

"Oh... a fox mask, ekekeke urokodaki still has the balls to send people here" The demon roared in laughter, completely forgetting that it's whole attack had been stopped by itsuki.

"Quiet of few of his disciple have been eaten here, sadly I never got to personally taste their flesh, but I guess it's different now" the demon roared as it reached out, its thick arms causing the air to turn violent.

Boom!!

The air collapsed, watching this incoming attack itsuki slowly walked up while clutching the handle of his katana.

Tap!

With a simple sidestep he dodged the attack, continuing his advance slowly towards the demon.

"Is that it?..... I waited so long for this? Why are you so weak?" Itsuki frowned, although he said this, his rage for demons only grew day by day the more he was inside this final selection.

"Are you fucking with m-" the demon shouted but didn't manage to finish its words, those two pair of cold eyes made it shudder.

Although it was 20 times the size of itsuki, he knew better than to judge someone by size when it came to demon slayers.

"Hit me... don't hold back" itsuki smirked, these normal demons were so easy to toy with, he couldn't wait for some real action.

"N-no" the long armed demon shook before trying to retreat, something about itsuki made it grimace in fear, as if it's life was already hanging by a thread.

"What is this feeling?" It had never felt something like this.

"No? Then die" itsuki said coldly, his eyes flashed with a sharp gaze as his sword flashed out.

[4th form: Winter Storm]

Releasing a cold breath of air as his katana made contact with the void.

Like the falling hail of winter, a myriad storm of katana slashes appeared in the air instantly, like a rain of bullets.

Boom!!

Boom!!

Boom!!!

The air was set into chaos as the winds parted, revealing only the traumatizing screams of the huge demon.

Tch!

Itsuki sheared his sword before walking off coldly, leaving behind him a frozen demonic body filled with dozens of holes.

...

"It's been nearly 5 days, yet nothing...nothing" itsuki sighed, although he thought he was growing too power hungry, that wasn't a bad thing afterall, anything could happen in this world, if he wasn't stronger than muzan, that was a problem itself.

Killing demons was indeed more beneficial, these 5 days he was already nearly level 18, this place was filled with demons, and with his overpowered strength he could swing his sword around aimlessly and still end up getting a 100x kill-streak.

After being here for so long, he knew the fat demon which Tanjiro fought wasn't the strongest, there were actually a few on par with it, like the one he had just fought was only slightly weaker, meaning it had ate less humans.

Itsuki's main goal was to reach level 20 and possibly unlock a new form, his strength was rising crazily since before, if he was comparable to a hashira before, he was now probably on a hashira's level.

But there was a problem....

Age: 15/80

He was doomed to die around 80+ years old, although it wasn't a problem as of current, but being a transmigrator, did he want to die like that?

Especially since the system promised more worlds, will be ever be able to increase his lifespan? This was his main thought this whole time, just like muzan....he was now interested in immortality.

Who wouldn't be.

Immortality was both a blessing and a curse.

But as long as itsuki was always the strongest, why would it be a curse? He only saw nothing but a blessing in his eyes.

"I'll think about it later" itsuki leapt on a tree before flashing off in the forest of trees like a shadow.
