the beginning 1

"Arthur"I got up after using my sword as a prop and looked at my injuries. I had at least three broken ribs, my left shoulder was dislocated and one of my ribs seemed to have punctured my lungs. I coughed up some blood and had difficulty breathing. . When I stood up with difficulty, I heard laughter coming from a completely black creature with black wings standing in front of me, or flying in front of me to be exact, holding a red sword with a thick black halo emitting from it. When he stopped laughing hysterically , he said, " I'll admit, human, that you are strong , but how long can you go on with these injuries?

Arthur with a smile:" don't worry, I can continue until you collapse first."

The Devil "Don't dream about it"

"You don't deserve a normal life, you don't deserve love, family and education, Arthur, remember this."

When he said that, he quickly rushed towards me with his wings and I took a defensive stance and our swords slammed into each other

'Arthur" it seems that I will have to come to Valentine's city again

It's confusing right? A stranger comes up with a strange beginning and talks about a city as if he were a stranger to it in fact, your lack of understanding of the topic is quite normal, so I'll explain a few things about this world. The planet we live on is Earth with some changes, of course. In general, there are four races on Earth (humans, demons, elves and dwarves.) Humans, dwarves, and elves can use mana normally, such as activating their items, casting spells, enhancing body and weapons, using potions, and other things. As for demons, they are characterized by the ability to change their appearance to anyone as long as they can see them. There is a negative thing, which is that they can only use it once a month because the transformation process is a direct match with the external appearance, eye color and everything, even their blood type. However, the slightest channeling of Mana or use will reveal the demon directly, as well as some abilities such as body enhancement or use (the dark element without mana, but using Ki energy and humans use mana to turn it into the dark element. This is the difference between the dark element in humans and demons. The Ki energy they possess differs from Mana in that it is limited only to the dark element. In addition, when a person is exposed to cauterization, it will lead to a decrease in the effectiveness of the use of the ingredient and reduce the effect of magic potions and treatment. As for demons, exposing their bodies to Mana will lead to a decrease in the effectiveness of their use of cauterization, which will lead to a slowdown in treatment as well, with a weakening of their destructive power and their own dark element. Therefore, a person must have good control of his element and good control of Mana to face a demon face to face. The most important advantage of this race is the restoration of lost limbs as long as the head and heart are fine

Demons have been fighting against humans, dwarves and elves for a long time, stretching back more than a hundred years. And the relationship is not good between humans, dwarves and elves because Elves and dwarves think they are more superior than humans! When the Demons took control of their home planet, they managed to enter the planet Earth through Mana portals, where they settled on almost 2/8 of the Earth's area, while humans had 2/8 of the Earth's area, Demons had 3/8 of the Earth's area, and 1/8 is not owned by any race yet because of the power of monsters in it, the randomness of their appearance, the difficulty of getting out of it, but because of the greed of demons to control the planets, they are now trying to expand their influence by controlling the remaining part of the Earth. In fact, the elves and dwarves were happy at the prospect of a new ally, but they were disappointed after seeing the weakness of the human race in terms of Mana control, Weak Flesh, lack of strong people to rely on, as they considered the human race to be a weak race and would hinder the elves and dwarves in their battles with demons

The relationship between the races can be described as chaos

Which means there must be someone who unites the three races together and defeats the demons and makes the world a better place and from this heroic speech

Regis: "Boy, when are you going to give me your body?"

Arthur: "What are you going to do with it?"

Regis: "Destroy your pathetic race?"

Arthur: "You couldn't defeat three members of the union and you want to destroy an entire race?"

Regis: "I wasn't at my full strength at the time because of the mana effect."

I took out a cigarette and put it between my lips and lit it and said

Arthur: "I agree with you on that point but what about the person who sealed you?"

Regis: "I will make sure to torture you both so well that you beg for death."

Arthur: "Yes, yes, of course you will do that."

For those who ask who I am talking to, he is the main demon responsible for destroying the orphanage I was living in because I don't know anything about my parents as they said they died in a car accident and as for how I got him when he was weak and on the verge of death After escaping from the union members, he wanted something to cling to in order to live, so he was destroyed the orphanage, I mean by destroying it, he completely erased it from the map. Then his ki energy ran out, instead of dying in a miserable way at the hands of the union members, he decided to seal himself inside me, which I know is a special ability that can only be used by the prince of the Demon King (the second strongest person according to the classification of demons), as he said that it is a special trait that allows him to move into the body of any living being once as long as he does not use ki because the being's ki will overwhelm the prince's ki, which leads to the prince's weakness according to the being's ki, so this idiot preferred to be inside me without any authority Since then I've been stuck with him, he appears in my nightmares and even talks to me through telepathy until I met someone I owe my life to, he saved me and made me work with him in exchange for housing, food and drink, where we would do assassination, spying, exploration and monster hunting missions (for the latter, he would just make me watch or make me fight G-rank ghouls because he said I was still weak) and I agreed with him on this, and he also placed seals made of mana that prevented the devil from controlling my body because it restricted him by them, and when the rest of the union members came to search for the devil, he said that he escaped, mentioning that there is no guarantee that the seals would last forever.
