Luminous Valentine

Luminous Valentine (ルミナス・バレンタイン) is a Demon Lord, the fifth seat of the Octagram, and the True Ruler of Holy Empire Ruberios. She is the ruler of all the vampires and one of the oldest demon lords.

Appearance
She is a cute silver-haired girl. Her heterochromatic eyes glisten in deep crimson and light sky blue. This, among her many strikingly beautiful features, is the most prominent one. What garners the most attention, are two pure white teeth that peek from within her small lips. When her small lips part, they reveal a set of pure white fangs. She is commonly seen wearing gothic dresses but seems to have a penchant for maid uniforms too.

Personality
Luminous is a usually haughty individual who basks in her superiority when sitting on her throne or when acting out her official position as a ruler, however, she has no problems with pretending to be a maid when it comes to hiding her true identity.

Background
In the past Luminous' Vampire country had been destroyed by Veldora. Due to that, she established Ruberios and became its ruler in the shadows.

Chloe Aubert
She thinks of Chloe as her savior and has great respect for her.

Rimuru Tempest
She is confused on her feelings towards him but she is somewhat envious of how close Rimuru is to Chloe but other than that they seem to have a mostly positive relationship. Luminous is however grateful that Rimuru mostly holds "that damn lizard" Veldora at bay and prevents any new rampages from happening.

Veldora Tempest
Veldora destroyed her original kingdom and she has never forgiven him, and all attempts to get on her good graces have ended in failure for the dragon. This doesn't help that Veldora accidentally reveals her name and her role as a Demon Lord.

Louis Valentin & Roy Valentin
Both Louis and Roy have been some of Luminous's oldest and most loyal servants in her thousands of years as a Demon Lord, with the two having both served her since even before the founding of the Holy Empire Ruberios. The twins themselves have dedicated themselves to being Luminous's body doubles within both her empire and her seat within the Demon Lord's council, with Louis acting as the Holy Emperor Pope acting as the leader of the supposed humancentric nation and Holy Church and Roy acting as the "Demon Lord Valentine", who "replaced" her seat within the Demon Lord council.

The Twins themselves show active reverence and loyalty towards Luminous and follow her commands to the letter.

Luminous in return has shown a strong sense of attachment to the two and was noticeably upset upon hearing of Roy's death and was saddened by her inability to resurrect him in time.

Hinata Sakaguchi
Luminous holds great respect for her and considers Hinata her right hand. She is very close to her, to the point that she is always worried about losing her.

Abilities
A genuine Rank S Disaster-class Demon Lord, specifically a True Demon Lord. Luminous was strong enough to defeat Hinata Sakaguchi in the past and was able to completely nullify her Usurper. She has the ability to resurrect herself or others from the dead due to her Ultimate Skill, she is also able to heal herself at an incredibly fast rate.

Trivia

 * She addresses herself as "warawa", which is an archaic pronoun used by women in samurai families. The author admitted that he intended to paint her as a haughty noble this way, not knowing that it's actually a self-deprecating, humble pronoun back then.
 * She has obvious yuri tendencies towards Hinata, shown by her enjoyment in making Hinata wear revealing clothing as well as seeing her naked in the bath. Same goes to Chloe Aubert, except that she doesn't have much chance to act it out.
