Becoming the Childhood Friend of the Character I Created

“Ugh… Gasp.. Huff.. Huh…!”

-Thud!

-Thump.. Thump..

At the top of the tower, 100th floor.

The pinnacle of the tower, where the Demon King resides, the apex predator of all beings, and the space where the high-ranking demons, the minions of the Demon King, roam.

Only beings so powerful that their mere presence could engulf an entire continent with their aura.

No one could dare underestimate their strength… or so it seemed.

What lay visible on the 100th floor of the tower were piles of corpses made up of demons.

“Huff.. huff… Puff!!! If… if it’s this far… even that monster won’t be able to come…”

Among them, the most formidable-looking demon. The only one among them was fleeing from an unknown entity.

“Darn it… I am the Demon King. I am the Demon King…! The apex predator of all beings!! Why… why is this unbelievable!!”

The lone surviving demon is none other than the Demon King himself.

Terrified, he was trying to escape from a being shrouded in fear.

‘Welcome to my domain, insect.’

‘Hmm? Are you alone in this place? …Ha! Seems like a suicidal maniac.’

‘Well, this is convenient; it was getting quite boring just staying here.’

‘Spend four years playing with you, waiting for you to leave the tower.’

Initially staggering like a suicidal maniac, with uncoordinated movements and unfocused eyes, she approached the demons in this tier.

Since the demons believed that a mere female could not stand against all the demons in this layer, they slowly approached her, thinking it would be an easy task.

And they were all swiftly defeated.

Even the Demon King himself failed to catch her movements, focusing all his might on her while his minions were rapidly perishing, barely managing to see her actions.

In her hand was a corroded and shattered old sword.

Yes. With missing teeth and a corroded old sword, she was cutting through the armor of high-ranking demons with enough strength to withstand attacks from top rankers.

“This damn woman!!!!”

A barrage of magical spears covered the sky towards the being that swept away all of the Demon King’s minions.

And the Demon King began to doubt his own eyes.

When exposed directly to magic, human skin decays rapidly and necrosis sets in. So what was this creature?

Like taking a stroll, she effortlessly dodged the rain of spears pouring down from the sky and casually pushed aside the spears falling in her path with her hands.

No attack could touch her.

No matter how powerful the magic poured out.

It simply did not reach her.

A monster.

The Demon King slowly spread his wings to escape from the approaching being.

No, he tried to.

“Gah…?!”

As he spread his wings, he felt a strange pain on his wings and saw holes pierced through them.

Upon seeing this anomaly, the Demon King turned his head towards the approaching being.

And there he saw a figure picking up scattered fragments from the ground and hurling them.

“This… this insane monster!”

Turning his body back, he began attacking the being that assaulted him and his minions while starting to flee.

“That… that’s no ordinary insect… it’s a monster!”

“I… I am not fated to die insignificantly here!!!”

“Yes… I am the Demon King. Though weakened, I can rise again.”

“Fleeing makes me sick to my stomach, but to see tomorrow, I must live. I must prove our ambition, that our demons are at the top!”

So, first, escape this tier and hide in another dimension…!

“-Found you.”

“···Huh?!?!!”

Sinister-

Before even realizing the presence following closely behind, the protagonist’s vision dropped as they heard the voice of the monster.

I have to escape. I need to run away. But why is my body right in front of me? Why has my vision lowered…?

“It’s because of you that I died again.”

“Not just you, it’s because of all of you that I kept dying, sacrificing everything to save myself.”

“Because of you, because of you, because of you, because of you, because of you, because of you, because of you, because of you”

“This time… I won’t let you die. I won’t let you get hurt. I won’t let you sacrifice. I will definitely save you.”

“At all costs.”

The monster muttered crazily in front of the demon king.

“You… insane… woman…”

The demon king’s consciousness was severed there-.
