"The past is gone and focus on the future" is what both my late brother and father used to say and that is what I intend to do this time.
I wanted power. The power to protect what I loved and not lose it. For demons, their power stemmed from their mana core mainly but they had 2 other outlets of power. Their mana beast and sacred guard. The mana beast that they can control can vary from just a normal dog to even the dragon of the skies. The most dangerous mana beast owned by a demon was recorded as 'Bahamut' the dragon of the end. Luckily the demon was stopped during its craze by the Bahamut's polar opposite 'Siegfried' the ultimate dragon emperor.
The battle shook up the world with vast powers coming into play including other sacred beasts. Demons summon their first mana beast at the age of 10 when they can control mana well enough.
Next the sacred guard, well not exactly a guard but rather a weapon can vary from demon to demon and is an exclusive weapon for each demon and allows them to channel their energies. The general age for summoning a sacred guard was 15 but there were cases of it appearing later or earlier. Sacred guards always chose their host.
You may have thought that I got my mana beast at an early age but no, I was normal like everyone except my family. My family consisted of only geniuses. My brother Jean unlocked his mana beast at the age 5 while my eldest brother unlocked his at the age of 7 while I unlocked mine at 10 like any normal kid. My mother had various doctors check me up just to make sure there was nothing wrong with me.
Now let me take this slow because I myself feel like the narration is pretty fast. Welp after I was born my mother already had me training physically at the age of 5. While my brothers were asked to train magic at the academy of Adam when they were 10, I was put through rigorous physical training at my own request. I pulled my friends Rigor and Theolen into my fights and also training my envelope to cover my body and fill up the empty void in me with the energy of the world. All I had to do was breath and that was training the envelope.
But each breath had to be done in a certain way or my entire body reached the peak of the pain like a million needles piercing me. As I reached the age of 10, I grew my first horn and my mother held the greatest banquet of all time inviting different nobles and even the demon king himself came to the party.
The party was full of life with people dancing and the king seated at a different station high above like one of those operas simply enjoying the time which is when I was invited by the king for small talk apparently.
The king sent a death fairy in the form of message. For the record death fairies when touched can cause the instant death to almost anyone except those wielding light attribute energies or energy wielders who've trained themselves to the extreme.
It was quite tricky to figure out the mechanism to these nasty fairies but I found it out to be that they don't like flowers. Flowers often symbolized life in various religions hence they who harbor death had an internal hate ingrained for these flowers. So of course, I wore a flower, specifically the 'demon crest' which symbolized the pride of a demon though most people didn't know this. I quite nervously touched the fairy and to my surprise I didn't die and the fairy seemed to snuggle up to me even with the flower on my chest.
It seemed to like me and guided me towards the demon king. He was given a throne made from bones at a high place such that he could overlook the entire event. The demon king had no symbols visibly but they could be hidden easily by coating them with energy.
"You know you won't be finding my symbols with that weak energy of yours. Though it's peculiar to see that you have no energy, a void to be exact and yet you wield it. Its quite unusual indeed but you don't seem nervous while meeting me, most kids would either fear or be elated upon me but you show no such emotions."
One thing that shocked me was that the demon that sat on the throne was actually not the demon king, instead it was the Cat on his lap. A black cat with splotches of red which was also a weird color pallet but the moment the cat opened its mouth, a huge wave of miasma poured out which was more than what I could handle.
The man spoke "master he may not be able to handle your miasma due to his mana void. I advise for a recall of the miasma as it might affect the party." The cat swept the air and all the miasma vanished like it had never existed and I fell to the ground finally being able to breathe. My mother stood behind me "maybe I should train you harder since u couldn't handle that fraction of miasma. Your brothers could handle it better but even with your void I expected better but whatever you can always go stronger."
Instantly I felt as if the demon king was nothing in front of my mother with her wide grin showing how demonic she was. "Mom let me at least take a break tomorrow."
Well, that wish wasn't granted, instead I got pummeled by my mother. Though that didn't affect the mood of the party. The king gifted me the fairy as a birthday gift. As I was drinking Haworth juice extracted from one of the most dangerous flowers in the 6 lands the demon king pointed towards a corner of the room. There in a wheelchair sat a girl with blindfolds and her hands restrained some shackles.
I turned on my spirit view that came along with the envelope energy. In essence envelope empowered the entirety of my body by multiple folds like a dress compressing when folded and when I focused all that energy on my eyes, I could see a lot far beyond the surfaces in a non-weird way. Inside her I saw what I lacked, what had seemingly left me alone was abundant inside her. She had a full energy core to the point where it was overflowing and that was as rare as my energy void. It was a blue orb overflowing like water in a cup in contrast to my black void.
Usually, these cases weren't as dangerous but, in this case with no prior treatment for her energy abundance she has accumulated a lot and now even a single movement of Her's could be catastrophic or I've read. I've never seen a case so close so I said "welp that girl is nearing her end, for such a cute girl to have such a small life span Is truly painful."
The demon king said "that's my daughter" and spit out the juice and I was in deep danger because of spitting the juice, my mother was glaring at me and I knew I was screwed. Another point was that I just called the demon king's daughter cute and also just said that she was gonna die.
