The Strongest Demon King Beginning From Kuwang Academy (DxD)

Chapter 1 My sister is Gurefia

The underworld, the legendary place where demons, fallen angels and many elf ghosts live.

Inside a splendid castle.

"Drink…ha…"

A teenager is trying to swing a sword in the yard.

"Nine thousand nine hundred and ninety-seven… nine thousand nine hundred and ninety-eight… nine thousand nine hundred and ninety-nine… ten thousand!"

"Huh…huh…"

The young man got down the long sword in his hand, wiped the sweat from his forehead and gasped.

The sixteen-year-old boy had short silver-white hair and bright black pupils.

Although the handsome and handsome face is still a little immature, there is a trace of perseverance and calmness on his body that does not belong to this age.

"Roy can't be lazy! Today, he has to swing his sword 100,000 times!"

A cold and serious voice sounded behind him.

"Understood, sister!"

Roy nodded helplessly.

"Really, every time I practice, I'm so serious, it's not cute at all."

Roy muttered a few words and continued to swing his sword.

Roy is a traverser, and it is impossible to know how to traverse. His current name is 'Roy Lucifergus'.

At first he came to this world, he was still a little skeptical.

But a few years after he came into this world, Roy was fully confirmed.

The world that brought him back to life was the world of Demon High School.

Demons, fallen angels, goblin spirits, angels…even dragons and gods.

These existences that should have existed in fantasy are all real in this world.

And the person who spoke just now was his sister, named Grefia Lucifergus (Greyfia Lucifergus).

It is the family member of the Demon King Lucifer in the original book, known as the strongest queen among all the family members of the underworld, nicknamed the silver-haired queen of annihilation.

But now she is no longer the queen of Demon Lord Lucifer.

Grefia was born outside the preface, the famous Lucifer Gus family in the demon family, the family has been the confidant of the old demon king Lucifer for generations.

During the reformation of the demons, she fought against the reformers as a member of the old Demon Lord faction, and finally competed with the Demon Lord Serafuru for the seat of the strongest female demon.

Although the competition failed, its strength is already the first level of the Demon King.

This also made the Lucifergus family a powerful demon family in the underworld and broke away from the Lucifer family.

However, due to the fact that the entire Lucifergus family was at war with the Reformers, there were only two people left.

And Roy is the last male of the Lucifergus family.

Originally, Roy thought that he was born into a famous demon family and had such a powerful sister.

Then he must be able to have a strong strength, hang down the major demon kings, and take all the girls he likes as dependents.

In this regard, Lysa Phoenix can be said to be a role model for all demons.

However, the ideal is beautiful, but the reality is cruel.

As the last heir of the Lucifergus family, Roy does not have a strong talent for cultivation.

Although he has worked hard to cultivate for more than ten years, now he is only the strength of a lower-level demon.

Look at Rias and Kurana, who are the same age, they have already reached the strength of high-level demons.

This kind of talent even he wanted to give up training, but his sister Gurefia did not give up on him.

He still stared at him sternly every day to finish his training.

And it is precisely because of this that the name of Roy's waste material spread in the underworld.

But he didn't care either.

"99,997…99,998…99,999…100,000!"

"Huh…huh…"

"Finally finished the sword swing training!"

Roy bent over his knees with trembling hands, sweat dripping down his face, he didn't have time to wipe it.

However, this is only the beginning of a day of training.

"Roy take a break first! I'll start learning magic later!"

Looking at Roy who worked so hard, Grefia finally showed a smile.

"Phew… I know my sister!"

Hearing that he could rest for a while, Roy was finally tired and sat on the ground.

After a short rest, it was time to learn magic.

However, with his waste talent, he has only learned a few basic magics over the years.

Such as teleportation array, erasing memory, magic bullets, healing magic and the most important contract magic and so on.

If you want to make a contract with a family or a familiar, you must use contract magic.

Of course, you still need demon chess pieces to sign a family.

Devil's High School is a very exciting world, although humans make up the majority of this world.

But only demon kings and gods are the masters of this world.

Of course, there is Orpheus, who is called the infinite dragon god, and the real red dragon god emperor, that is, the dragon called the great red.

These are all beings that stand on the ceiling of this world.

In such a wonderful world, Roy is naturally unwilling to be ordinary. It is absolutely impossible for him to let him watch the girl he likes fall into the arms of others.

Since you are not willing to be ordinary, then let's be vigorous!

If you don't have the talent to practice magic, you should practice swordsmanship well.

When other children are playing, he is practicing.

When others are resting, he is still cultivating.

And it is precisely because of a madness that his swordsmanship has been perfected.

As far as swordsmanship is concerned, he is confident that no one in this world is his opponent.

He was just an ordinary person in his previous life, but since he came to this dangerous and wonderful world, of course he has to realize his dream.

To realize your dreams, you need a lot of strength.
