****First, My Brother was the only Family I had, he always accompanied me and always spoiled me.
My father and mother died when I was born, when the power went out of control and devoured everything around me.
My parents were first consumed by my power that was out of control.
It was my brother who was with me then and sealed me, he absorbed all my strength and threw it away in Hell.
–And since then, we live together as the top-tier Demon Nobles [Bellzebub].
There were about 8 top-tier Demon Nobles back then, we were one of them. The Demon King will be chosen from every talented child of the Demon Nobles and the chosen one will rule over all the Demon races.
My brother and I are the only members of the Bellzebub Demon clan.
We always played, competed, sometimes had hunting picnics, and practiced magic together.
–It was so fun.
If not wrong, I was very excited and told my brother.
[Sister!, I will become the Demon King and protect Brother!]
–My brother smiled gently while laughing and stroking my head
[Galius is a powerful Devil, I'm sure Galius can!, he said!,...My brother will support you.]
Therefore I decided to learn magic to become a powerful Demon King, who can protect Big Brother.
It's just an ordinary kid's dream...
~But, I didn't know that it would destroy the entire Demon~ race
One day, I learned magic in the middle of the forest, in front of me was Monster Rank A [Dark Tiger].
I have a talent in controlling all magic other than holy magic.
But, other than all magic, I am most talented in using the special magic of the Bellzebub clan, that is...
[Babelluzebub!]
I said that, and just then also appeared a puddle of black mud and devoured the [Dark Tiger] Monster.
The nobility of Bellzebub had a special magic that devoured everything. The meaning of Bellzebub is Gluttony.
[I succeeded!, This is amazing,...With this I can become a Demon King, I'm sure Big Brother will be proud of me!]
I was so excited, and I ran to the Mansion where my brother and I lived together.
....
But...
[What this is!.]
I trembled as I entered my mansion and fell down.
Inside the Mansion were many servants serving the Bellzebub Family, but now they died cruelly.
In the Mansion it was filled with blood.
I ventured and entered it.
I saw a servant I knew and approached him.
[Bu Jila! Madam Jila!,...Uncle Sam!, what happened?!]
I wiggled their bodies, but unfortunately they were all not breathing.
I could not breathe regularly and was terrified.
Looking at the trail of blood heading towards a room, I followed it while trembling.
In front of me was a big door. The door opened a little.
Swallowed my saliva and I opened the door slowly.
I get ready with my magic if it's in danger.
–And I opened Pandora's box**...
[****Sister!]
I saw my Brother who was covered in a terrifying black aura, inside the room were many traces of blood and corpses of servants.
[Aah~Galius, Welcome.]
My sister smiled gently at me and greeted me warmly like nothing had happened.
'Impossible, What happened?, I?,..Is this the brother who did it?,..But, Big Brother right?', those thoughts kept flooding into me.
My brother, who realized what I wanted to know, said.
[Galius, in this world there is no more Demon race than Big Brother and you,...My brother has destroyed them all.].
[Eh!.]
While I was surprised and confused by what my brother said, he continued.
[...With this Galius could become a Demon King. All of the Demon Nobles Clans were already brothers to kill, so Galius did not have to worry about the trash rival that was blocking Galius from becoming a Demon King.].
Something inside me is missing, I can't hear anything anymore.
[Well.., though it was a little troublesome killing them, but Big Brother can!, though!,...Galius let's be Demon Lords, we'll always be with~]
My brother kept smiling like he was nothing while swinging his sword to play.
I bow my head. Right now I can't think straight, my pupils darken to blankness.
–As for my brother muttering how he defeated the top-tier Demon Nobles, the ground shook and a shouting voice sounded from outside our Mansion.
[Devil Bellzebub!!, Your Mansion is currently surrounded!,...Come out you filthy Devil!!]
My brother and I were a little surprised and went out of the Mansion.
There are creatures that are said to be [Humans], there are thousands of human troops with complete weapons.
In the midst of that army and the front of that army. I saw the golden blonde little girl and carried the glittering holy sword.
I couldn't turn my eyes away from the beautiful golden blonde girl.
It was night, so I could see a golden hair of the girl glittering.
He looked lonely and lost something precious.
The girl looked at me expressionlessly.
My brother hugged me from behind and whispered.
[Galius, devour them with your strength, I'm sure they are delicious!]
But, right now my eyes can't run away from that golden girl.
[Basic Devil scum!, you killed your fellow!, Really the Demon clan is savage!,...But, we must thank you for killing that troublesome Demon Nobles clan, now that you are left!, die!]
A human who said that looked old, he smiled arrogantly, and his followers cried out in excitement.
[Oouuhhhh!!.., Heroes please kill them!!]
[Save this world, Hero Liza!!]
[Kill that savage Devil!!]
All the troops took up their weapons, but...
[Be quiet!!!, Let me do it myself!]
[....!]
The golden-haired girl screamed for them, and everyone was silent.
Heroes, is that what they say?...
The hero who will kill the Demon King as in the stories.
I know the Demon King and the Hero are fighting each other, but, right now I can't turn my eyes away from that Hero.
My chest is pounding, this is weird!
The hero is so beautiful.
–After that, the hero looked at me sharply while doing the horses to attack.
We looked at each other.
Then he muttered.
[Sad!]
I feel annoyed, but, right now I'm getting excited.
I don't know this...
[Sister!]
[What's Galius?]
[I want to become a Demon King and fight with Heroes!]
Without turning my eyes away from the Hero, I said that, and somehow my brother looked surprised.
I made a condescending look at the human, and smiled arrogantly while saying.
[Look at the lowly Humans!, Right now I will become the next Demon King.]
[Ap!.]
Everyone was shocked and vigilant after I said the statement out loud.
[Hero!, I look forward to your presence in my Demon King castle,...Right now I'm going to let you go.]
The hero twitched in annoyance, and without a cue he jumped up and attacked me with his holy sword.
[Chi!]
I avoided her with flying magic. My sister followed me too.
[Fuhahahaha.., You're still a weak hero right now, let's meet again as you grow up.]
[Galius, aren't you going to devour?]
[You're right Brother!, I need more magic energy, Alright.].
I stretched my hand upwards, the Hero looked alert and jumped up to attack me.
But, my brother parried his attack with his sword.
I also cast my magic.
[Babelluzebub!]
A ball-shaped black mud was above them, the human troops were in a panic.
[What is that?!]
[Run, That's the special power of their clan!]
[Aaaahhhhh!, the Demon King has risen!!]
Fear and panic ensued beneath me, they began to run around in despair.
I muttered.
[It's too late!]
The black mud ball fell and hit them, it broke and became a puddle of black mud, then devoured half of their army...
Everything falls in Desperation except the Hero.
He glared at me with sharp eyes and we looked at each other.
[My name is Galius Bellzebub IV, the demon who will become the next Demon King, remember my name is the Hero of mankind!, See you~]
After that my brother hugged me and used teleport magic to leave.
[Let's go Galius, Teleport~]
---\=\=\=---
From then on, my name was widely spread throughout the World as the next Demon King.
I built the Demon King's castle, there I built my strength and army with my brother.
But, after that my brother went somewhere in secret**.
