So, there is one thing common in all vampires, any guesses? Well mate, definitely their big pointed teeth! Otherwise, they won’t be a vampire. We all can judge that he is a vampire by having a glimpse at his teeth.

Let me tell you! He appears to be a bit scary because he has an angry and prideful look on his face. The scar on his forehead makes him look dominant and somehow cool as well. Okay, so the truth is the truth!

He has a lean body and you’ll find him aged, as I said he is the complete opposite of our charming vampires! Besides, the reason why you find him aged is that he is more than 1500 years old. That makes him even scarier!

But yes, he looks in his forties; a well-maintained vampire, why not!

Fun Fact:
He looks a bit handsome in the anime, so you better watch him there! (Anime Episode 38)




As his name suggests, he has a pretty cool royal look but not a royal personality. His blonde hair and Royal clothes make him look quite cool. But let me tell you, all his royalty is destroyed when he utters a word.

Huh! What else can we expect from a negative character? He does whatever he feels right, without caring about the feelings of others. As said by Demon Lord Kazareem: “That man, Valentin, views humans and demi-humans as mere food” (Manga Chapter 73)

If still, you haven’t got an idea about his personality, then read his words listed below!

“Silence, you defile God’s seat, trash insect! I will judge you myself and you may die with that honor” (Manga Chapter 72)

He said those harsh words when he prohibited someone from entering a sacred place (Church). Well, people like him who consider themselves not less than a god, why would they care about a sacred place?

So, I bet now, what’s said by Kazareem, and Roy himself, we got a clear idea of his ugly personality, right? In short, the words “pride, arrogance, and egoistic” define his personality well!

Strengths and Skills


Superhuman Skills

We all know that vampires have a lot of powers and that’s obvious because they aren’t ordinary human beings. To talk about Roy Valentin then he is pretty strong and an ordinary one can’t stand a chance against him.

We can predict the level of his powers when he easily attacked Laplace in the Church.  That’s when he prohibited him from entering a sacred place. (Manga chapter 73 and Anime episode 34)

Besides, he is not an ordinary vampire that has got some powers. He is really a bother to other powerful characters in the manga and anime. We can say that because this is what Kazareem said: “Running away was a correct decision, Laplace. During my prime, he was a man whose strength rivaled my own” (Manga Chapter 73)

Magic Abilities

Let’s talk about some of his skills and powers. Though he has a lot of skills and abilities, one of them is his signature technique and that is “Red Beams”. That is pretty unique because Roy uses his blood for this one. To get a better idea about his technique, let’s read the information Kazareem gave to Laplace when he told about red beams:

“Blood which is transformed into magical particles and shot out. It is a technique called “Blood Ray”. He is known by the moniker of “Bloody Lord”, and that technique is a specialty of his.”

So, now we know that Roy Valentin is a strong and powerful vampire!


  • The name “Roy” means “KING”. So, now we know why he has so much pride and attitude.
  • He has a scar on his forehead
  • His age is more than 1500 years
  • He died after a series of incidents
  • Louis Valentin is his twin brother



As he is a side character, so, a complete detail of his background isn’t known. His major role was a subordinate of Luminous. He worked as a member of “Ten Great Demon Lords”. By judging from his personality, we can easily say that he spent his whole life killing people in a void and of course because he is a vampire!

Well, his fight against Lord Kazareem caused immense destruction because of the strength of combined powers. Besides, his powers alone are so immense that they would have a drastic effect on the surroundings as described by Kazareem:

“I have fought with him a few times in the past. In those fights the surrounding towns and settlements would get dragged into it.” (Manga chapter 73)

From the above information, we came to know that he had several fights with Kazareem in the past.


Ten Demon Lords

Ten Demon Lords

As it’s mentioned above, Roy was a member of “Ten Demon Lords” after he started working for Luminous. Other than that no specific information is known about him since he is a side character.

? Question mark ? unknown

Louis Valentin

Besides, he has a twin brother “Louis Valentin” He had a general interaction with other ordinary ones. One thing is clear that His master and brother are the most important relations in his life.


So, guys, we have already discussed how Roy bothered Laplace and what was his behavior. Also, we came to know how ugly and powerful he was. As he is a side character, you would rarely find him in anime or manga. After a series of incidents in the manga, it’s revealed that he died in a battle.
