Demons are one of the greatest threats humanity has ever faced since ancient times, they are feared by the majority because of their dark nature.
They treat humans like livestock and food for them to eat. In the history of humanity there is one Demon King who is feared by anyone in the upper realm, he killed all humans left and right as he devoured their souls and continue to strengthened himself, whether it's a child or not, they will be killed and be devoured without exception.
He was drowned by his greed for power. He almost killed and plunder the souls of the humans in one of the largest Empire in the upper realm and because of his disturbing actions, the 7 Great Kings was forced to take action to stop this growing calamity.
As he was in his ecstasy of being able to devour billions of souls as he grow stronger than before, He was beheaded by the Great Kings.

Inside a cave, A golden-horned demon is sitting on the throne as he rests his head on his hand with his eyes closed. At this very moment, he was having a dream of his past life
After a minute, the demon opened his eyes and muttered "I've been dreaming my past life as I fell asleep, those bastards been tormenting me even now, just you all wait. I will have my revenge and devour your souls too" said the demon with a glint in his eyes
He always dreamed of the scene of being tortured and killed by those so-called 7 great kings. He was so angry that his head was full of vengeance.
"just a little longer, I will have your souls soon and wipe out your descendants." Said the demon then he closed his eyes again.

"Esri do you know how strong demons are? Do they also have magic hierarchy or something?" Asked Shinichi curiously
The five of them are now flying to the City of Circe. Esri and Lisa are on Elly's back as Shinichi and Reina are flying beside them. Lisa, for the first time, that they saw a big change in her facial expression when Elly suddenly enlarged in front of her but it suddenly returned to her normal bored looking face
"Demons are much stronger than humans in terms of body strength. According to the information I learned, demons didn't cultivate they are using human souls to achieve power. They are more vicious than a magical beast." Said by Esri
Demons can evolve by the number of souls they devoured. They have 5 evolution from Lesser Demon, Greater Demon, Arch Demon, Demon Lord, and Great Demon Lord.
Lesser demons are the weakest kinds of demons known to exist, they didn't think properly they are like dolls who only listened to higher demons.
Greater Demon is the evolved form of Lesser demons, they are the one who commands lesser demons, they can think like a normal person and their strength is similar to the magus stage.
Archdemons are the evolved form of Greater Demon their strength is with the range of Arch-Mage to Grand Mage.
Demon Lord is the next evolution of Greater Demon, they are marked as a threat level that needed the entire Kingdom's power to defeat it.
Lastly, the Great Demon Lord, they are the calamity level in humanity in this realm they are strong enough to conquer this entire lower realm.
"and a long time ago according to the ancient text that I read, this lower realm is almost conquered by the greater demon, it is said that almost any magic in the lower realm won't be able to kill that Greater demon." Said by Esri
"You said almost so it means that, that greater demon is still killed right?" asked Shinichi
"Yes, it was the sword emperor who killed it and it is said that it was the first appearance of the sword emperor." Replied Esri with a twinkling star in her eyes.
'Looks like this girl's adoration towards the sword emperor is bigger than I thought. Is this the reason why she fell in love with me? I wonder.'
"Shinichi Onii-chan are we going to fight demons?" Elly asked
"Yes Elly, do you want to fight too?" replied Shinichi
"Can I eat them?" Asked Elly
"Of course, you can... Wait, what? What are you saying, Elly?"
"Hmm, demons are delicious they have lots of energy than a magical beast." Said, Elly
"Is that in the memory of your mother that she left you?" Shinichi asked
"Mhm, mama is fighting a demon and devoured the Demon" Elly Replied
"Really? Urgh. Will you not be affected by that demon if you eat it?" asked Shinichi
"Mhm, etttoooo, according to mama, if demon go to my tummy it will incinerate and turn to pure energy" explained Elly
"I see, that memory of Emily-san really is helpful to you if not, we won't be able to know how you will become stronger, also your good at talking now, if I won't know that you just born 2 months ago, I will think that your 8 years old or something.
'though I still have Hestia to ask how can make a phoenix stronger'
"hehe~ Am I genius onii-chan? Am I genius?" Asked Elly cheerfully
"of course, you're a genius," said Shinichi as he patted her head
"hehehe~" Elly giggle
"Let's farm some demons then, kukuku how many demons do you want Elly?" Asked Shinichi with a look of a villain on his face
"Kukuku, If possible I want to eat all of them onii-chan" replied Elly as she copied Shinichi
"Kuku, you're a greedy one Elly, alright then, let's get you some barbeque demons and roasted demons kukuku," said Shinichi as he continued his act
"Kukukuku" the both of them laugh like a crooked
The three girls' eyebrows twitched as they heard the two of them talk as if demons are just food for them to eat.
"Haaa~ for the first time in my life, I felt pity for the demons," said Esri as she sighed
"Mhm, Mhm" the two girls agreed and nodded
