Roy Valentin

Roy Valentin (ロイ・ヴァレンタイン) is the body double of Demon Lord Luminous Valentine. His strength is at the level of a Demon Lord Seed. He was killed on his way back from Walpurgis to defend the inner sanctum of Ruberios.

Appearance
Roy Valentin appears to be a tall man with blond hair with regal clothing befitting a Demon Lord.

Personality
Roy is a prideful individual who sees many others as below him. Despite this, he's actually very loyal towards his master, Luminous Valentine.

Background
Originally there was a powerful and bloodthirsty Vampire known as "Valentin," who was known for being highly bloodthirsty and battle crazed and so even after being taken in as a subordinate under Luminous after being subjugated by her, he continued to antagonize her other subordinates, causing Luminous to then use her powers to divide this vampire into two separate beings. Creating both "Roy" to act as her body double and his twin brother "Louis" to act as Holy Emperor of Holy Empire Ruberios.

Since then Roy together with his brother has continued to loyally serve Luminous for a very long time, even before Ruberios came into existence.

After the founding of Ruberios, he acted as the Demon Lord to terrorize people into joining the religion of Luminism, while his brother acted as the pope to lead the religion.

Sometime while pretending to be the "Demon Lord Valentine" hundreds of years ago prior to the formation of the "Ten Great Demon Lords" when the council only consisted of a mere seven members, Roy had apparently gotten into an argument and battled against "Curse Lord" Kazaream and had fought him to a stand still. Despite no clear winner being made from their battle, it was confirmed that the sheer destruction caused by their fight had caused massive damage to their surroundings and a large amount of civilian casualties. Its been stated that due to the result of this battle being triggered by a disagreement between them, a "tradition" of the Council agreeing to the vote or motion supported by four members or so is allowed in order to avoid another incident such as this. These rules were seemingly established when the group itself consisted of seven members.

Plot
Roy Valentin was first seen acting as the Demon Lord Valentin together with a maid, who was Luminous in disguise, during the Walpurgis Banquet. After his and Luminous' true identities were revealed by Veldora, Luminous ordered him to go back and defend the inner sanctum of Ruberios.

On his way back he encountered Laplace, who had just been repelled from the Inner Sanctum by Hinata Sakaguchi. At first, Roy was cornering Laplace despite being weakened by the new moon, but after Roy started mocking the deceased Clayman, Laplace got enraged and killed Roy by using the strength and techniques that Laplace normally keeps concealed.

Relationship

General Abilities and Skills
Due to having served Luminous Valentine since ancient times and as one of her oldest, most powerful followers, Roy possessed a majority of the common abilities and powers of a vampire but also obtained the most advanced skills and powers as well. Because of this, Roy's overall power level was equivalent of a Unawakened Demon Lord Seed.

Notable Techniques

Trivia

 * Both Roy's and Louis' first names, as well as their surname, are pronounced in French.
 * During his battle against Laplace, the backstory and true identity of Roy and Louise being once a single being divided into two is revealed. And upon Roy's death, he was then re-absorbed into Louise. As such Roy can still technically be "alive" through Louise.
