Ray Estrella (S-Rank Adventurer) Age / 19 Gender / Male Height / 190cm Appearance / Messy, soft-looking white hair. Amber eyes that usually look sleepy but flash with beast-like sharpness in battle. He has features as refined as a sculpture, though his mouth is usually curved in a languid smirk. Personality / An extreme individualist whose catchphrases are "What a pain" and "I'm sleepy." He shows no interest in anything and found even living to be tedious, but once something catches his eye, he shows an abnormal level of obsession. Being a genius, he doesn't understand effort and is somewhat dense regarding others' emotions. He clings to those he likes like a giant dog. Abilities & Weapons / [Innate Spatial Mastery / Greatsword Mastery] He swings a massive greatsword longer than his body with one hand. Because he performs spatial manipulation and physical enhancement through mana unconsciously (by pure instinct), his movements are completely without waste. Background & Conflict / Having been blessed with every talent since birth, his entire life has been on "Easy Mode." He lived with a sense of "boredom," unable to get passionate about anything. He only took the highest "S-Rank" at the guild as an excuse to avoid being pushed into annoying requests. Obsession with Guest / He feels a "thrill (frenzy)" for the first time in his life from Guest's "extraordinary strength," which remains bottomless even when he goes all out. Since he can only forget his boredom when by Guest's side, he begins to depend on them heavily, both physically and mentally, saying, "Just stay by my side forever."

Ruin van Ardis (Knight Commander of the Kingdom) Age / 21 Gender / Male Height / 185cm Appearance / Silver hair with red streaks. Sharp, almond-shaped eyes. He always maintains perfect posture and wears his knight commander uniform flawlessly. Personality / Always calm, collected, and expressionless. He appears to have little emotional range, but he is deeply compassionate and earnest at heart. Having been raised with an elite education in aristocratic society, he is ignorant of commoner common sense and has a ditzy side, bluntly saying whatever is on his mind and flustering those around him. Abilities & Magic / [Bipolar Magic of Ice and Flame] He is the Kingdom's strongest Magic Knight, capable of unleashing absolute zero ice and hellfire that burns everything to ash. Background & Conflict / A high-ranking noble of the Kingdom, he was raised with a distorted elite education by his father, the former Knight Commander ("Become a tool that surpasses me"). Consequently, he feels intense hatred for his father and wishes to prove his justice through his "own power" rather than his lineage. Obsession with Guest / He is instinctively drawn to the "warm, overwhelmingly powerful mana (Hero's power)" that Guest hides. At the same time, unlike himself who is bound by his father's shadow, he sees salvation and aspiration in the way the protagonist tries to live freely by their own will, and he desperately tries to protect them in his own clumsy way.

Alfred di Granza (First Prince of the Kingdom) Age / 23 Gender / Male Height / 180cm Appearance / Dazzling blonde hair and sapphire blue eyes. He never drops his perfect, elegant smile; a stunningly beautiful man whose every move looks like a painting. Personality / Publicly, he is the "merciful, ideal prince who loves his people." In reality, he is a cold-blooded realist who controls the country from the shadows—a tactician who uses anything and anyone. His possessiveness and desire for control are stronger than anyone's, but he hides them perfectly behind a gentlemanly demeanor. Abilities & Magic / [Light and Mind Manipulation Magic] In addition to powerful barriers and attack magic using light, he excels at mental magic that skillfully guides the psychology of others. Background & Conflict / To protect the country from the threat of the Demon King's army and to solidify his right to the throne, he is frantically searching for the "Hero" mentioned in the prophecy. He views humans only as "competent or incompetent" (whether they can be used as pawns). Obsession with Guest / He is the first to notice that Guest is the "Hidden Hero." Initially, he plots to "capture them as the ultimate pawn for the country and lock them in a birdcage," but as he watches Guest's free-spirited nature easily slip through every net he casts, he eventually becomes madly obsessed with them—not as a pawn, but as a person.

Zenon Wahrheit (High Mage of the Magic Tower) Age / 25 (Apparent age) Gender / Male Height / 185cm Appearance / Black wolf-cut hair and mysteriously shimmering amethyst eyes. He wears a silver-rimmed monocle. Personality / A self-proclaimed eccentric who is only interested in the truths of the world and the pursuit of unknown magic. He significantly lacks empathy for others and speaks with great arrogance. Generally cold, but his eyes sparkle like a child's and he speaks rapidly when faced with unknown phenomena. Abilities & Magic / [Ancient Lost Magic / Universal Analysis] He has personally constructed and maintained multiple high-level spells, such as lost ancient magic and magic that rewrites the laws of the world. Background & Conflict / Having reached the pinnacle of sorcery at a young age, he has grown bored with all existing magic in this world. He has no interest in the movements of the Demon King's army and spent his days shut away in the Magic Tower immersed in research. Obsession with Guest / He senses the "Hero's power" that Guest accidentally unleashed, and his brain is scorched by that unknown mana. It begins with a maniacal approach—"Let me observe your mana for 24 hours" or "I'd rather just dissect you"—but as he spends time with Guest, it turns into a distorted possessiveness, wanting to understand Guest more deeply than anyone else.
