Luminous Twilight Valentine 「ルミナス・トワイライト・バレンタイン, ruminasu towairaito barentain」, known primarily as Luminous Valentine 「ルミナス・バレンタイン, ruminasu barentain」, is a Demon Lord who holds the fifth seat of the Octagram and is one of its oldest members. She is the queen of all Vampires as well as the true ruler of the Holy Empire of Lubelius, where she is worshipped as the "God" of Luminism.

Appearance

Luminous is a youthful-looking woman, having an imperfect yet complete beauty, as if she was trapped in the very moment when she matured from a girl to an adult. She has heterochromatic 「金銀妖瞳ヘテロクロミア, heterokuromia, lit. "gold-silver mystic eyes"」 eyes that glisten in deep crimson and light sky blue, with a set of pure white vampiric fangs.

She is commonly seen wearing gothic dresses but also seems to have a penchant for maid outfits. After regaining her memories as the Divine Ancestor, Luminous grew a few centimeters taller and the colors of her eyes switched. She also has a male form with an appearance almost identical to Twilight Valentine.

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 for possibly a long time.

She also enjoys classy food and entertainment, so much that she asked for a musical exchange after watching the concert in Tempest's opening festival.

Background

Luminous was born as the result of an experiment conducted by the Divine Ancestor Twilight Valentine. At some point while they were creating their High Disciples, Twilight experimented on themselves by dividing their being into two entities: one that had their body, powers and the majority of their memories, and the other that only possessed their personality, with Twilight sealing the memories of their true identity inside the Origin Blood.

In spite of this, Twilight considered Luminous a remarkable creation and hailed her as their masterpiece. However, as time passed, Luminous grew weary of her creator's capricious behavior, and with a display of extraordinary power, she ended Twilight Valentine's life using a potent Disintegration spell. Seizing control of the vampire forces, Luminous subjugated Valentin, one of Twilight's many creations and a formidable Vampire, known for being highly bloodthirsty and battle crazed. Yet, even after this, he continued to antagonize her other subordinates which posed a significant problem. To maintain order, Luminous was forced to make the difficult decision to divide Valentin into two separate beings: Louis and Roy.

In due course, Luminous encountered Gunther, the original ancestor of the modern Vampire race. After ruling as the king of Vampires for many years, Gunther eventually pledged his unwavering loyalty to Luminous and entered her service as her noble assistant and trusted aide, fulfilling the role of her personal butler. Recognizing Gunther's invaluable contributions, Luminous elevated him to a position of great importance, and he became an instrumental figure in her rule.

Through her indomitable prowess, Luminous earned a coveted position as the fifth member of the esteemed Demon Lord council. However, her vampire domain, known as Night Rose 「夜薔薇宮ナイトローズ, naito rōzu, lit. "Night Rose Palace"」, was ultimately brought to ruin by the Storm Dragon Veldora around 2,000 years ago. This attack was the result of a scheme orchestrated by the Trinity Wisemen, who harbor bitter feelings towards Luminous due to her murder of the Divine Ancestor and various disagreements. They had deceived the True Dragon by falsely informing him that Luminous had personally challenged him.

Fortunately, thanks to the timely warning from the Hero Chloe, its inhabitants were able to safely evacuate before the attack began. Undeterred by this setback, Luminous turned her attention towards a new endeavor: establishing Lubelius, where she ruled from the shadows. To govern Lubelius, Luminous entrusted the role of ruler to Louis Valentin, while she herself assumed a hidden presence. To maintain her influence within the Ten Great Demon Lords, Luminous arranged for Roy Valentin to take her place, attending the Walpurgis Banquets incognito as one of Roy's two aides. Her sudden disappearance from the public eye and replacement among the ranks of the Demon Lords led many to believe she was dead.[1] She was able to keep this ruse for 1,500 years before her cover was inadvertently blown by Veldora and Milim Nava.

Throughout these tumultuous years, Luminous forged deep bonds of friendship with Chloe and Hinata. When Chloe and Hinata's younger selves ventured into the Central World and vanished from Hero Chloe's body, Luminous took measures to safeguard it by sealing it away, preventing any potential chaos instigated by Chronoa.
