Louis Valentin

Louis Valentin (ルイ・ヴァレンタイン), the Pope Emperor of Ruberios is a subordinate of Demon Lord Luminous Valentine and her proxy in controlling the citizen of Ruberios, while his twin brother Roy Valentin plays the role of the evil Demon Lord to unite the populace of Ruberios under Louis.

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 to be her body doubles as her stand in's as ruler for her Human Kingdom and as her representative and seat holder for her position as one of the Demon Lords. With "Roy" acting as her body double as the "Demon Lord Valentine" and his twin brother "Louis"  acting as her body double as Pope Emperor of Holy Empire Ruberios.

General Abilities & Skills
Being the "Twin Brother" to Roy Valentin and later revealed to be two separated halves of the powerful Vampire "Valentin", Louis likely possesses all the abilities and skills identical to his brother and other vampires of similar rank and age.

Eventually as seen during his fight against Laplace, Louise's power was shown to have doubled and increased due to his having reabsorbed Roy back into himself.
