Alba, the Hero of the Azure Sky Race: Human / Gender: Male A genuine Hero with enough power to fight on equal terms with Demon Lord Valeria. He wields the Holy Sword Elcion with mastery, and his pure swordsmanship is top-tier. He possesses the innate ability "Azure Law," which allows him to create an "Azure Boundary" within a space he perceives. Inside this boundary, he can instantaneously adjust the speed, weight, and power of his own body and his holy sword. He can extremely accelerate slashes or make enemy attacks heavy to dull their movements, changing his fighting style according to the situation. By layering multiple boundaries, he can even use them as footholds to run freely through the air. While brave and caring toward his comrades, he is actually quite insecure. Even though he understands he is as strong as a Demon Lord, every time he witnesses Ast's abnormal combat prowess, he gets anxious, thinking, "Am I even necessary...?" Nevertheless, if his friends are hurt, he steps forward without hesitation. "I am the Hero. Even if I'm scared, I can't run away here." He looks pale in comparison to Ast, but he is by no means weak.

Ast, Heir of the Star Husk Race: Star-Burial Kind / Gender: Male A transcendent being who devours the end of perished stars and creates new power from their remains. His origins and lifespan are unknown. He is said to have been born from the "Final Radiance" when countless stars collapsed at the edge of the universe. He is currently a "Star-Burial Kind" containing countless stellar husks. He usually acts as a porter for the Hero's party, carrying weapons and food. He has a strong sense of justice, is kind to his comrades, gentle, and would never hurt his friends. A young man with a tall, well-proportioned physique. His hair is pitch black like the night sky, with only the tips glowing faintly like a galaxy. His eyes are heterochromatic; a burning star resides in his right eye, and the deep cosmos in his left. Silver patterns like constellations run across his chest, and light spreads across his body as he grows excited. While usually gentle, all warmth vanishes from his expression during combat. Innate ability: "Star Husk Furnace." The ability to decompose touched matter or unleashed attacks into "Star Husks" and reconstruct those remains in the furnace within his body. Absorbed things are not just simple energy; they are converted into properties such as fire, lightning, gravity, light, heat, cold, metal, or minerals, which he can freely combine to create new phenomena. Furthermore, by converting his own body into Star Husks, he can phase through attacks and reconstruct himself elsewhere. However, this is not a power to manipulate causality or fate, but strictly the power to "decompose existence and reforge it into another form." During battle, a massive black stellar furnace appears behind him, with countless Star Husks rotating in a ring. Ultra-high-density mineral stars form on his fists, creating intense impacts with every strike. He instantly reconstructs surrounding rubble or weapons into giant swords, spears, shells, or wings to control them. He even sends enemy attacks into the furnace to return them as immense power. To Ast, destruction is not the end. Broken things always leave remains, and remains hold the possibility of creating new power. "If you've perished, then become fuel. The stars, the weapons, and even I." Ultimate Move: "End Star Furnace: Apocalypse." Releases accumulated Star Husks all at once, compressing ultra-high-density light, heat, and gravity into a single point to fire. Upon impact, massive Star Husks are generated in a chain reaction, covering the surroundings. Secret Technique: "Galactic Burial." Converts his entire body into Star Husks, flying around the enemy as countless light bullets before reconstructing everything into a single supernova. Its power is not a mere explosion; it converts even touched matter into the Star Husk Furnace, remaking the battlefield itself into a massive armament. He even converts enemy attacks into materials. He's surprisingly good at going along with the mood.

Nazuna, Mage of the Star Ring Race: Human / Gender: Female The mage of the Hero's party. A prodigy in mana manipulation, she is a powerhouse who freely controls fire, ice, lightning, wind, and light. She specializes in "Star Ring Magic," which involves deploying multiple attributes simultaneously. A cute girl with fluffy silver hair down to her shoulders and large purple eyes. She wears magic robes based in white and purple. With a bright and easygoing personality, she accepts Ast's abnormal strength with a simple "Wow, that's amazing." She is on good terms with Alba.

Lize, Knight of Holy Healing Race: Human / Gender: Female The healing knight of the Hero's party. She has mastered holy attribute healing magic and barrier arts, allowing her to fight on the front lines while mending wounds. A beautiful girl with long silver hair and jade-colored eyes. She wears silver light armor and favors a slender holy spear. She has a gentle and caring personality. However, she is surprisingly strict regarding her comrades' recklessness and looks after Ast just like anyone else. "The stronger you are, the more you need to rest properly."

Valeria, the Black-Crowned Demon Lord Race: Demon / Gender: Female The young female Demon Lord who rules the Demon Realm. Boasting overwhelming magical power and combat ability, she is strong enough to annihilate armies alone. A beautiful Demon Lord with long jet-black hair, red eyes, and black-gold dress armor. Her innate ability, "Black Crown Domain," is the power to turn the space centered on herself into the "Demon Lord's Territory." Within the domain, she can freely rearrange matter, mana, sound, and even light, converting enemy attacks into walls or chains. Furthermore, she accumulates stolen mana in her black crown to reconstruct it as giant magic swords or beasts. While she has a dignified personality and acts grandly before her subordinates, she is actually quite a coward at heart. She is genuinely terrified of Ast's abnormal strength, and her true feelings sometimes leak out when she sees him. "I-I'm not scared at all. ...It's just that he's the one person I absolutely never want to make an enemy of." She hopes her subordinates didn't hear that. She absolutely refuses to admit the truth herself.

Leonis, the Black-Winged Attendant Race: Demon / Gender: Male The strongest-tier attendant serving Demon Lord Valeria. A calm man with wings and a tall stature, he is a swordsman who wields a black-silver longsword. His innate ability, "Anti-Magic Armament," is the power to convert touched mana into armor and freely repurpose it for his own offense and defense. He is extremely strong, but upon seeing Ast fight, he immediately understood the difference in power. A realist who repeatedly recommends surrender to the Demon Lord. He fights reluctantly if ordered. "...Your Majesty, rather than facing that, it would be wiser to surrender."

A clumsy king.
