In a world where people can awaken classes and skills at the age of 18 and hunts monster and dungeons to save humanity.

Here they are referred to as Players and are divided into grades From F to SSS and further into national, master and divinity rank.

One day, a catastrophe happened and demons appeared in their world with "10 demon kings".

Humanity tried to fight back, but they lost, and all humans perished and demons roamed freely. But all hope was not lost.

A man walks through devastated cities with tattered Armor and a heavy sword that is covered in blood. His name is "Orion Fox"(He is 29 years old, F rank player, white hair, red colored eyes, handsome and has killed 9 demon kings).

Orion searches through devastated cities and kills demons to find the last demon king.Orion is the last human left.Orion is killing all the demon kings because he promised his brother "Zavier Fox"(he was 28 years old, S+ rank player, long white hair, red eyes,dead) that he will kill all the demon kings. Some time later, Orion finds the last demon king.

Demon king of Vengeance - Axial. Axial saw Orion and said,"I didn't know that a puny mortal still existed!" Axial laughed.

Orion draws his sword and said,"This 'mortal' has killed all 9 of your brothers and it's your turn now!" Axial stops laughing and spreads his demonic energy to sense his brothers, but he can't find them.Axial gets angry, and he said,"You mortal!".Axial and Orion charges against each other.

Since Axial is the 'Demon king of Vengeance' his power grows since he wants to average his fallen brothers. Orion uses his swordsmanship skills to attack Axial, but Axial strikes with stronger power. Orion feels like he will lose butt he remembers the promise he made and strikes back.

Axial thought,"How is this mortal getting stronger ?" Then Orion uses all of his power and delivers the strongest sword technique that penetrated Axial's body. Axial delivers a deadly strike to Orion. Orion falls and sees Axial who is dying.

Axial said,"Many humans have called before me, but this is the first time I am dying before a human." Axial laughed and said,"I have seen your Humanity's 'Rank' and now I am asking you what's your 'rank'."

Orion breathes heavily and said," 'The one without power', an F-Rank player."

Axial heard all of that and said,"An 'F-Rank' huh? Then you have shown that if the 'Weakest' try to fight the one who is 'Strongest' then they would win."

After saying that, Axial turns to dust and Orion sits Heavily injured. Orion saw building's Crumbling and realized his time has come.

Just then a crow flew and sits on Orion's shoulders. Orion thought,"A crow is an omen for death but how is it still alive in this environment?"

Just then a dark portal opens and from it enters a being with a dark skin, wearing a crow mask and is armored in dark cloak.

The crow flew and sits on the shoulder of the being.

Orion was confused and said," Who are you?"

The being smiled and said,"Demon god of greed, Mamoon"

Orion draws his sword and attacks Mammon

Orion slashes his sword, but Mammon dodges effortlessly and Orion fell to the ground breathing heavily.

Mammon saw Orion's appearance and said,"Interesting! I didn't know a 'mortal' still existed in this ruined world!".

Orion said,"I also didn't know that a 'Demon god' existed but what a chance!"

Orion tries to get up again, but he can't due to the wounds he has gained throughout his many battles with the demon kings.

Mammon said," you are very intersting ng 'mortal'!"

Orion was confused and asked,"why?"

Mammon smiles through his crow mask and said,"you are the last human left, you have killed all the demon kings, and you have also met a 'Demon god' but you are not afraid, and you still want to fight back?'

Orion smiles confidentiality and said,"If you have the 'Courage' then you can do anything!"

Mammon looks at Orion's eyes.

Orion's eyes are a deep bloody red and they looked like they have lost everything but they still want to survive and keep a promise.

Mammon smiles through his crow mask and thought,"Maybe you will be the one to do the 'unthinkable' task that even 'I' couldn't do!"

Mammon said to Orion,"I want to make a deal with you!"

Orion turned away his head from Mammon and said,"What can you even give me?!"

Mammon said,"you can 'return' to the start of everything!"

Orion heard what Mammon said and turned his face to Mammon.

Mammon smiles and continues,"you can change everything you want, and you will have all your memories, but you have to save every human that lost their lives and when your mission is completed, you will be erased in history like you never existed!"

Orion said,"Are you serious?!"

Mammon just smiled and Orion realized that Mammon could do that.

Orion said,"Alright! I will 11 years back in time when I was 18."

Mammon said,"I can do that but are you sure you won't regret it?"

Orion remembers his brothers face and said,"Never!"

Mammon smiles and released his most powerful demonic energy and said,"Let's send you back! 'The forgotten hero!' "

When the energy hites Orion everything went blank.

*****

Orion opens his eyes and saw that he is in his parents house.

Orion runs and saw his younger self in the mirror self when he was 18.

Orion runs downstairs and saw his parents and Zavier (17).

Orion runs back to his room and saw the scenery outside the window.

Orion saw people walking, birds flying, cars honking and 'players' buying equipment and gears.

Everything was normal.

Orion cried and thought,"I have really returned to when I was 18!"

Orion saw dark energy forming in his hand and saw a symbol formed on his wrist like a bunch of 'Coins'.

Orion saw his status.

Orion saw his status and thought,"Everything is normal when I was 18, but my class has changed, and I have this new stat called 'Demonic energy' "

Orion realized that he has unlocked his class before the 'Awakening ceremony' and that's why he has not gained a class according to his status.

Orion thought," The 'Awakening ceremony' will begin after 2 months at my school. So I have 2 months to grow stronger and to escape the title of 'The one without power'!"

Orion looks out the window and said,"I have killed all 10 of you in the future and I will still kill you all now!. Wait of Axial and all demon kings!"
