Roy Valentin

Roy Valentin (ロイ・ヴァレンタイン) is the body double of Demon Lord Luminous Valentine. His twin brother Louis Valentin plays the role of the Pope of Ruberios. 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. When he was in the inner sanctum of Holy Empire Ruberios, he would wear a white clergy robe similar to Louis', so that people would not know he's actually the 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 Vampire known as "Valentin," who was known for being highly bloodthirsty and battle crazed. Even after being subjugated and taken in as a subordinate by Luminous, he continued to antagonize her other subordinates. This caused Luminous to then use her powers to divide this vampire into two separate beings, creating two separate entities to act as her body doubles. In this way, she could stay hidden out of sight of both the other Demon Lords and her human empires. "Roy" was assigned to act as her stand-in as a member of the Ten Great Demon Lords, while his twin brother "Louis" was to act as her stand-in as the Holy Emperor of Holy Empire Ruberios. Both of them have continued to loyally serve Luminous for a very long time since then, 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 Valentin" hundreds of years ago (prior to the formation of the "Ten Great Demon Lords" and the council only consisted of merely seven members), Roy had apparently gotten into an argument and battled against "Curse Lord" Kazaream and had fought him to a standstill. Despite no clear winner being made from their battle, their fight had caused massive collateral damage and a large number of civilian casualties. It's been stated that due to the result of this battle being triggered by a disagreement between two Demon Lords, a "tradition" of the Council agreeing to the vote or motion supported by four members was set in place in order to avoid another incident like this. These rules were seemingly established when the group itself originally 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.

Trivia

 * Both Roy's and Louis' first names, as well as their surname, are pronounced in French.
