  When I activated the demonic library skill, a sort of domain and also a dimension were summoned ience, one where I felt like I could freely enter or step out at any time. Ihere seemed to be a world of its own, one where the sky was red with bck clouds and a green-colored moon.

  The ground was made of bck or red stone, with strange, demonic crystals growing out of it, faintly illuminating the endless corridors. The bookshelves themselves were made out of the ground’s stohemselves, as if they had been shaped from them.

  Ihe bookshelves, there were many books, perhaps thousands of them across this entire dimensional domain. I don’t know if it was truly endless, but as I walked around it and spread my Immortal Senses, I realized it was incredibly vast, but not endless.

  It was roughly the size of Texas, though.

  And it wasn’t everything a library; although there were mostly bookshelves, there were alse opehat led to subterranean caves.

  I wao check what was inside of them; there were more of these glowing crystals and strange, demonic ores, but first I looked at the grimoires themselves—all of these books.

  Well, not all of them were grimoires though; some were empty, others had information and knowledge, and only a couple dozen, perhaps around thirty or so, were actual grimoires with spells and something inside of them.

  I think that, as the skill level increases, these books will obtain knowledge and spells, I suppose. I ’t just have the entire library at full power after all.

  “Now let’s see—oh!”

  The moment I grabbed one of the grimoires, it shook, beginning to move on its oowerful bd red energy emerged from within, which made the air around it very heavy. It seemed to be releasing a lot of pressure.

  “Free me! Free me from this pce, librarian!”

  I heard a voice whispering to me from the book—a strange, evil voice. I immediately assumed that it was some sort of demon or something. I don’t know how it even ended here inside of my skill.

  “Sure.”

  I opehe grimoire pages as red and bck smoke surged from the book, taking the form of an imp-like demon with red skin, a pointy tail, a bald head, pointy ears, and a long nose, holding a trident.

  “Gyehehehe! You freed me! You actually freed me, you fool! Once I kill you, I’ll bee the owner of the library!”

  He pointed his trident at me and rushed to fight me, trying to pierce my body with it. I could feel within him a rge amount of raw strength, enough to easily impale all S ranks.

  CLASH! CLASH! CLASH!

  However, I reflected his blows with my bare hands, or well, with the nails of my fingers, which I had painted gold because I liked that color quite a bit.

  “Hmm, so, how did you end up in this library?” I wondered.

  “Eh? Why are you s?!” He screamed before I kicked his chest, trying to put some distaweewo.

  BAAAM!

  However, it seemed the kick was to because he quickly exploded into red smoke and dissipated after giving an unsightly, ghoulish scream.

  “Guuaagh…!”

  As I heard his st scream, the red smoke went back to the grimoire, and the grimoire closed itself, showing a number of fmes on top.

  It showed the number 10.

  After waiting a minute, I lear wasn’t a mi was ten hours of cooldown until I could summon this particur demon again.

  “Iing…”

  I grabbed anrimoire and summohe demon ihis one didn’t eveo me. When something appeared, I saw what resembled a floating eye with maentacles attached to it and a pair of golden horns.

  “Hopefully it will go differently; I believe you won’t try to attack me, yes?”

  “Bubuuub! Blururururub!”

  It couldn’t even speak, I see.

  “Hah, go back.”

  I quickly sent it back to the grimoire and started looking for a demon that could speak to me and wasn’t an asshole. It took me three more shots, but I finally found someone willing to talk to me who didn’t look like some hideous creature.

  “Huh? Wha…? Where am I?”

  It looked like a petite woman, wearing a blue mask for her face, with pointy bck horns, long, silky bck hair, and scaled arms and legs; in fact, she had scales around her entire body; even if she was nude, she didn’t look like that.

  Truth be told, she was quite beautiful, with her wide hips and puffy chest, apanied by her beautiful mask-fad that long, silky bck hair.

  As a person reciates the beauty of all women, she was beautiful without a doubt.

  “The hell! Where did you e from?! You spooked the hell out of me!”

  Her pointy tail waved around the sed she saw me; she was scared.

  “Sorry, I was just admiring your appeara is quite different thaher demons,” I said. “And you talk! Do you have a name?”

  “Name...” she wondered. “I... Beelzebian Belzeeraskhasn Sataniankicha Herbellzuhbub. But you just call me Belze for short.”

  “Quite a faname you have.” I said. “You see, I just created this skill, and all of this appeared. You demons were also sealed in these grimoires; there’s this library. And there are many other mysteries I have yet to find out. Okay, my first question. Was this library already made beforehand, or was it created by them?”

  “Hmm, so you’re the new owner... No, it could be said it’s both,” Belze said. “This is an a prison, actually, for very bad demons that disobeyed the Seven Archdemons or rebelled against them. It is a Dimensional Space that remains hidden within the Abyssal Void between the Worlds of the Tower. Once every few thousand years, someone is chosen to wield this power. Usually, a key is given to the chosen one by the Seven, but... but you got it from a skill?!”

  “Yes! It seems that I somehow hijacked your prison and made it into my power,” I ughed. “I guess that’s part of what my System do now.”

  “W-What the hell?” she muttered. “I ’t believe that! Is this true?! Ah! Wait, the entire area ged appearaoo. And you’re right, it is more like a library now. Most of those books are empty, though.”

  “I imagine more demons will appear ohe skill increases its level,” I expined as we walked across these arid demonids.

  “Hah… Hahaha…”

  She started to ugh as she began running around.

  “Hahahaha! It’s true, someone actually stole the Endless Demon Prison?!”

  She began to jump around and dance.

  “Yes! Finally! We finally start fighting baow!”

  “Um…”

  “Ah! Right, my bad.”

  She walked towards us.

  “Um, what was your name, master?”

  “Master? Ah well, my name is Bing Xue, also Katherine.”

  “What a weird name! Well, you already know my name and our circumstances. You’ve somehow itted a grave crime. By creating this skill, somehow you were able to create a e to the Prison, and you’re now actively helping all prisoners escape into your library.”

  “I did that?!”

  I was just intending on making a new powerful Skill, but it has now bee the way out for several demonic criminals that have been imprisoned and sealed away by the Seven, the Archdemons that seem to govern all demons iower.

  “Yes! I don’t know how you even made this Skill; I see its name or something?”

  “Sure…”

  I quickly decided to check the skill iail; I was sure I had missed several effects within it.

  Once I opes description, it was rather long.

  “Oh wow, okay, I’ll he gsses.” She whisked her fingers as red and bck smoke materialized into a pair of gsses, which she wore as she started reading, squinting her eyes. “Um… Uh-huh.”

  “Wow, this is really long.” I said. “But at the same time, quite simple, isn’t it? Although it doesn’t go into detail about what these Abyssal Curses, Demon Sorcery, or Demonic Arts are all about..."

  “Hm, I see, I see,” the demon dy said. “So it is as I thought, though there’s somethihis weird essence you ow extract from it. Also, you, as the Librarian, receive our powers as well.”

  “Demon Powers, huh?” I wondered. “I am already very strong, so I don’t think I hem, but perhaps iure I could.”

  “Heh, don’t uimate what demons do, young dy,” she said.

  “Young Lady?! I am over eleven thousands years old, dear,” I said.

  “So? I’m past my huhousand years of age!” she said.

  “Oh…” I muttered.

  “Well! I guess for a human, you’ve lived plenty, but our demons never really die. Or, well, even if our bodies perish, our essenever truly disappears; we go back to Hell, and then we have to find a new tractor t us out. You are that for all of us, a tractor that bring us to the world out there.” Belze expined. “And I, for once, would like to apply as your secretary. I see you’re quite fused about everything. So how about you leave that job to me, Bing Xue—I mean, dear master?”

  She seemed a bit ing, but she was still below my Authority at the end.

  And she was cute.

  “Hmm, fine… You’ll have to do a few tasks for me first to show me you’re petent, Belze,” I said.

  “Hah! Sure, tell me anything.” She readjusted her gsses, quickly materializing some clothes.

  Her clothing was quite casual but cute: a bck overall-like dress with a white blouse, a bck witch hat, bck heels, and white stogs.

  She truly looked kind of like a cute little secretary.

  “Then your first task is reanizing the entire library; make me a list of what every book is for, from demons to spells and so on,” I said.

  “That sounds really hard, but bring it on; I’ll do it!” she said. “If I ever bee your secretary, I want some payment, though.”

  “Hahah, quite bold, aren’t you? Fear not, your efforts shall be paid well.” I nodded. “Now, if you excuse me, I am quite busy, so I’ll get going.”

  “Once you return, you’ll see everything well anized, master!” she said with a fident smile.

  “I am looking forward to it then!”

  I stepped out of the dimensional domain; barely a minute had passed iside world.
