Prologue-Human To Demon

Allos.

That's my name.

No surname.

Just Allos.

I was told that my parents gave it to me before they passed away for some unknown reason after my birth.

Because of that, I lived my entire life in an orphanage.

The kids thought my name was weird, although I didn't say it. I felt I was at least loved enough by my parents to be given a name, unlike the others.

...But everything changed the night after I turned 27...

After a long day, I immediately went into a deep sleep...

After hours of sleeping, I woke up with my eyes closed and tried to go back to sleep.

'Hm? Why do I hear the flow of a river?'

'Do I smell wood?'

'Why does it feel so breezy?'

Unable to take it anymore, I opened my eyes.

Upon waking up, I was greeted by a forest in front of my eyes.

"What, the...?"

I was stunned by the scenery I was in.

As I got up from the tree I was lying on.

A forest scenery surrounded me.

'Did I get kidnapped?'

I looked everywhere, and that was when my eyes struck something shocking. The Sky.

Multiple planets could be seen with the naked eye, even with the sun shining down on the world.

"Is this...?"

Ding!

'Huh?'

[The name -Allos- has been registered to the system.]

[New species has been added!]

[Changing species -Human- to -Demon-!]

[Would you like to proceed?]

Startled by the sudden floating messages, I thought about the situation.

'This isn't earth.'

'... and judging from this system, I must be in a magical world.'

'And now this system is asking if I want to become a Demon...'

After a few moments of thinking, I gave a huge smile, followed by a burst of laughter.

"Hahahaha!! Finally, I got away from that boring life after all this time!"

After a few seconds of laughter, I again looked at the message in front of him.

[Changing species -Human- to -Demon-!]

[Would you like to proceed?]

'A Demon, huh?'

"Why not?"

[Target has agreed to the change!]

[Beginning evolution!]

The moment I read the last message, a sudden surge of pain engulfed my entire body.

"Ackk!!!"

'What the hell is this?!'

[Completion: 2%]

As the pain continued, Allos's body changed bit by bit.

His teeth became sharper.

His black hair gained more strands of white hair.

His bones became stronger and darker.

His muscles got bigger.

His blood became black.

[Completion: 46%]

All the while, he endured the excruciating pain.

'I feel like I am going about to die!!'

But the changes to his body didn't stop.

His skin became paler.

Two black horns grew from his head.

A huge amount of demonic energy entered his body.

[Completion: 72%]

As well as the color of his eyes changed from brown to obsidian on his left eye and a deep-dark purple on his right eye, with both eyes' sclera turning black.

[Completion: 80%]

And finally, the final touch to a Demon.

A pair of beautiful, black-featured wings sprouted from his back.

[Completion: 100%]

[Species change has been completed.]

In the end, there was Allos, soaked in a cold sweat from head to toe, trembling a little, veins popping out while gasping for air in his new appearance.

"...Haha, is it finally done?"

I say in a weak voice while also barely maintaining a straight face.

Ding!

[Would you like to see your status?]

I got a little angry at the message.

'You bastard. Asking me now after making me go through that much pain without warning?'

"Sure, open it up."

I, now standing in my Demon form, read through my entire status, and while reading through it, I questioned many things.

'14 years old?! What the hell is this saying??'

'I'm clearly 27-'

Just as I was about to complain any further, I checked my entire body. My body was bigger than it was earlier.

I was taller; I gained a bit of muscle, despite all that, even in my new appearance...

...I clearly looked like someone in their early teens.

"Was this because of the transformation? Or was I 14 the moment I got here?"

After a few moments, I accepted it and moved on to my next complaint.

"Why do I only have three skills? Is this all a Demon gets?"

-Mind Seclusion-, -Flames of Hell-, and finally, -Disguise-.

I gave a bit of a frown at the three skills.

'The only one that sounds useful is -Flames of Hell-.'

I thought about it some more and decided to try the skill out.

'Do I just... think about it...?'

[-Flames of Hell- has activated!]

At the same moment as the system message, my left arm was engulfed in a black flame.

"Woah! This is actually pretty cool!"

'I can feel the magic power flowing into my arm!'

After a few seconds of admiring the flame, I deactivated the skill and moved on to the next one.

-Disguise-

"Hmm..."

'This might be useful.'

I thought about using the skill like I did the -Flames of Hell-.

[-Disguise- has been activated!]

'If this is what I think it is, then maybe...'

I lifted my pale right arm and thought about changing it back to my normal skin color, and it worked just like I expected it to.

"Haha! I knew it!"

But I didn't stop there. I changed my whole appearance into a normal-looking human.

Everything worked until I reached the wings.

[Unable to change target.]

'What? Are these wings permanent? No... maybe I just...'

I thought about retracting both wings, and surprisingly, it worked.

I now looked like a normal 14-year-old human.

'Well, I guess this isn't a totally useless skill. I can use this to deceive some people.'

I smirked a bit at the thought.

"And then there was one."

-Mind Seclusion-

I didn't know what this skill could do, yet I felt it could be useful.

'Let's see.'

[-Mind Seclusion- has been activated!]

The moment it was activated, my body collapsed to the floor, followed by a blackout. Five seconds later, I opened my eyes and saw pure nothingness.

"W-Where am I?? Did I die??"

Confused, I looked around me, but it was all the same; it was just pure nothingness.

Ding!

[Welcome to your own training room!]

'Training room?'

[Here, you can train your body, skills, and stats.]

[Improvements in this training room will also affect your real body.]

[Time is significantly faster than the outside world.]

[Bonus reward!!]

[Create a new rule for your training room!!]

After reading all the messages that popped up, I smiled again in my Demon form.

"So it wasn't useless after all."

[Create a new rule for your training room!!]

'A new rule...'

I spent some time thinking about a new rule for this skill.

Then I had the perfect rule that would strengthen me.

"The ability to make any skill."

[...]

[...]

[...]

'Was it too much?'

[New rule has been granted with a few adjustments!]

[Alteration 1: Only able to create up to five skills per 21 days(Real World Time)]

[Alteration 2: There is a limit to how powerful a skill is depending on the user's power and the training room's level.]

[Alteration 3: Users will be given a book full of skills they can choose from.]

[Alteration 4: The skill -Mind Seclusion- leveling rate has significantly slowed down.]

[New Rule has been added!]

"I guess even the system has limits. Either way, this is a huge win for me."

Ding!

[Status has been changed!]

'Hmm? My status?'

"Open."

[Unable to open status inside -Mind Seclusion-.]

"What? Fine. Deactivate the skill."

[-Mind Seclusion- has been deactivated.]

Once again, I blacked out, and five seconds later, I opened my eyes to the same spot where I had collapsed.

"I don't think I'll get used to that soon."

As I got up from the floor, I questioned my skill.

'Aren't I defenseless in that state?'

Luckily, the system answered.

[When in -Mind Seclusion- your conscious will automatically return whenever in a dangerous state.]

'That answers that. Now, what change did I get?'

Elements: All...]

'Would look at that. I'm able to use every element now. I guess I made a good rule then.'

Satisfied by the big change I got, I was ready to undergo my new life.

"Now then..."

"Let's start this new life!"

Feeling as if nothing could stop me, I ran to my new life, but...

...I didn't even make it 10 meters when I ran into something that made me fall to my ass.

"Ugh! What the hell was that?!"

Angered a bit, I checked what was in front of me, but nothing was there, nothing at all.

Confused, I reached out, and sure enough, there was something like an invisible barrier preventing me from going any further.

Knowing this, I got angrier and went in a different direction, but it was the same, a barrier, another direction, barrier, the other direction, barrier.

Then I opened my wings and flew up. Surely that would work, but in the end, it was the same no matter what.

At this point, I got so mad that I activated -Flames of hell- and punched the barrier at full power with the black flame.

"Let me out, goddamn it!!"

The hit caused the ground to tremble and make a loud boom noise.

But even that wasn't able to do anything.

In the air, I let out my anger.

"Why? Why! Why!!"

"Why the hell can't I leave?!!"

Filled with anger, I shouted at the top of my lungs.

Sparks came out of my body as if it was reacting to my anger.

But I knew this wouldn't change anything, so I calmed down, and so did the sparks.

I returned to the ground and retracted my wings. I then walked to the barrier and touched it, and then went in a circle while touching the barrier.

While walking, I collected my thoughts until I made the full circle. Although I didn't want to admit it, I was stuck here.

At least for now.

I let out a deep sigh and looked at the center of the barrier.

A tree.

A single tree.

It was clearly separated from all the other bunched-up trees.

I walked over to the tree and placed my hand on it.

"I guess it's just you and me."

With not being able to go anywhere, I only had one thing I could do.

"-Mind Seclusion-."

[-Mind Seclusion- has been activated!]

I blacked out.

***

Two months have passed since I came to this world.

In these two months, I learned new things about the world and myself.

'It seems like I don't have to eat as long as there's magic in the air... I still want to eat some meat, though.'

'All five of my senses have increased significantly. I can sense at least 150 yards away from me... why is there nothing but trees in this goddamn forest?!'

'This tree seems to have a faint trace of magic inside of it. Do all living organisms have a bit of magic?'

In these two months, I also train my ass off inside my skill and reached a completely different level than when I came here.

'I think I gained a lot more than I thought.'

I was happy for a bit that I became a literal Demon.

But even after all that training, I still couldn't leave the barrier.

I tried hitting it, but it was in vain, as not even a scratch was on it.

Then I started training once again, thinking that I could never leave.

Until one day...

***

On one sunny day, a pair of young girls were taking a stroll in a forest.

"Hey, Alisa, don't you think we're going too far?"

One of the girls asked the other.

"Hmm? I don't think so. Why? Are you perhaps scared, Elien?"

The other girl, named Alisa, responded.

"W-What?! I-I am not!"

The first girl, Elien, talked back with a slightly angry voice.

"Haha, I was just joking."

Elien grumbled a bit before speaking again.

"But I'm serious. What if there's a monster this deep in the forest?"

"Impossible. My father already cleared out all the monsters near our village."

Alisa said that, seemingly proud.

"I know that, but that's only near our village, and this isn't near our village."

"How much are you going to-"

Suddenly, Alisa stopped talking and walking, which then startled Elien.

"I-Is there something wrong?"

Alisa pointed her finger in a certain direction.

"Is that a person?"

Confused, Elien looked in the direction Alisa was pointing at.

"Hmm...? Yeah, I think that is. What is someone doing this deep in the forest?"

"I could say the same thing about us."

A little freaked out, Elien tried to get the both of them out of the forest.

"Hey, Alisa, let's head-"

Before Elien could finish talking, Alisa ran in the person's direction.

"H-Hey! Where are you going?! We don't even know if that person is good or bad!"

Feeling forced, Elien also ran and quickly caught up to Alisa.

And before they knew it, they were at the location, and what was before them was someone lying on a tree, seemingly sleeping. But that wasn't all. The person looked like someone in their early teens.

The first to speak was Elien.

"Is that a boy? He looks young. He has some weird sense of style, though."

Elien stared at the boy's hair that reached the shoulders and his weird clothes that she had never seen.

Alisa also stared at the boy in front of her and approached him.

"A-Alisa!"

Not reacting to her name being called out, Alisa continued to get closer and bent her knees to be face-to-face with the boy's sleeping face. Since he had long hair for a boy, Alisa brushed his hair out of the way of his face.

In awe, she said, "It is a boy."

[Another living being has approached you.]

[Would you like to leave -Mind Seclusion-?]

"Yes."
