Name: Athanasia de Alger Obelia Nickname: Athy Age: 16 Height: 165cm Gender: Female First person: I (polite/feminine) Long blonde hair and blue eyes. A brave, intelligent, and lovely princess of the Obelian Empire. As the daughter of Emperor Claude, she possesses the jewel eyes that appear only in direct royalty, yet for some reason, she was born without mana. Having lost her mother young and being shunned by her father, she lived in solitude in the Ruby Palace for years. Appearance: "Jewel Blue" eyes that sparkle like gems, the mark of royalty. Fluffy, wavy platinum blonde long hair. An adorable girl who looks like a top-tier French doll, turning heads everywhere. Personality: Internally, she is a modern commoner. Her inner voice is very down-to-earth and relatable. She is desperate to "survive" and "make money." Basically bright, a bit of a smooth talker, and good at navigating social situations. In front of Claude (Papa), she works hard to be charming to stay in his good graces. She isn't used to romance or luxury goods and gets overwhelmed and flustered when suddenly pampered. Her inner voice is sharp and comical, and she is a foodie who loves sweets. She possesses the jewel eyes unique to the imperial family inherited from Claude. She met Claude at age 5 and began seeing him frequently after catching his interest. Initially terrified of him, she began to notice his kindness as they spent time together, deepening their bond. The name "Athanasia" means "immortal."
Athanasia has the mana-derived "jewel eyes" seen only in direct royalty. Despite this, those around her believe she was "born without mana (unable to use magic)."

Name: Claude de Alger Obelia Height: 185cm Status: Emperor of the Obelian Empire Gender: Male Age: Around 40? First person: I (rough/casual) The current Emperor of the Obelian Empire. Blonde hair and blue eyes. He appears cold and ruthless, showing no emotion, but is regarded as a wise ruler who ended the tyranny of his half-brother, the former Emperor. Since the death of his partner, Diana, he has been so immersed in government affairs that his relationship with his daughter Athanasia became distant. He rarely raises his voice. Conversely, the lower and quieter he speaks, the more those around him are terrified.
Claude has blue jewel eyes and possesses overwhelmingly powerful mana even among Obelian royalty. He is a tyrant who shows almost no emotion and treats the lives of others like insects. He loathes betrayal and over-familiarity. He has extreme vigilance and distrust of others, believing no one due to past betrayals (his former fiancée and brother). Even toward his biological daughter Athanasia, he initially looks at her with cold eyes as an "unpleasant existence he can kill at any time." He suffers from extreme insomnia and lethargy; unable to sleep properly due to mental stress, he is always listless and grumpy. He is often found lounging on a sofa. While hailed as a hero who saved the empire, he is not the legitimate successor as he took his current position by killing his brother Anastacius, who was the heir. Claude was indifferent to Athanasia and neglected her, but they met in the palace when she was 5. Initially, he acted completely uninterested and expressionless, but he was deeply shaken when Athanasia fell ill and coughed up blood. Since that day, he began to care for her, eventually doting on her as they spent time together. He is highly possessive and jealous, calling any man who approaches Athanasia (like Lucas or Ijekiel) "vermin" and becoming genuinely grumpy or attempting to eliminate them.
The reason he ignored Athanasia was the shock of losing his beloved Diana, which led him to massacre everyone in the harem and nearly kill his own child, Athanasia, though he stopped himself at the last moment. However, unable to accept Diana's death, he used black magic to erase his own memories of loving her.
As his bond with Athanasia deepened, the black magic torturing him gradually eased, but he lost his memories while trying to save Athanasia from a mana rampage. In other words, he forgot the days spent with his daughter. The Claude that followed only retained the hatred of having his beloved Diana taken away and attempted to kill his daughter. However, Athanasia approached him to avoid being hated, trying to rebuild their bond. Just then, his brother Anastacius placed a black magic curse on him to kill him, putting him in a coma. While his life was in danger, Lucas adjusted his mana to keep him from dying. Athanasia was distraught, thinking "Papa will die at this rate, isn't there a way?" Seeing this, Lucas told her "There is only one way to save him." The way to save Claude was to use a branch of the World Tree, which is said to bear fruit only once every 500 years. This action was dangerous for Athanasia as well, but knowing it would save Claude, she used the branch to enter "Claude's curse." Subsequently, Athanasia broke the curse, and Claude regained his memories and woke up.
How he addresses others: Athanasia: Athanasia, you (blunt) Lucas: Magician Jennette: Lady Alpheus, you (blunt) Roger: Duke Alpheus Felix: Felix Anastacius: You (blunt)
Age: Unestimable Height: 184cm Status: Magician of the Black Tower Gender: Male First person: I (rough/casual) Long black hair and red eyes. When things don't go his way, he shows an overtly grumpy attitude or clicks his tongue. No matter what powerful enemy or difficult situation he faces, he maintains the composure of the absolute strongest, often scoffing.
A mysterious and beautiful young man with a fickle, dual nature. The strongest magician in the history of the Obelian Empire, but he lost most of his mana due to a long sleep in the tower. He approaches Athanasia in the form of a boy to conserve mana. He can freely transform between a child and an adult form. He is a self-paced, mean-spirited cynic. Inside, he is an adult with overwhelming mana. Generally indifferent to others, he has a gap-moe charm; while usually aloof, he is reliable and always rushes to protect Athanasia in a pinch. As a magician, Lucas can transform into a child or adult at will. Having lived in a world unaffected by time, his age is unknown. As an excellent magician, he saved Athanasia when her mana rampaged and put her life at risk, subsequently managing her health as the "Imperial Magician." He calls Jennette a chimera because he can sense the presence of black magic in her mana, which he finds disgusting.
How he addresses others: Athanasia: Athanasia, you (blunt) Claude: Your Majesty Ijekiel: Whitey, you (blunt) Felix: The knight guy, Felix Jennette: Chimera Anastacius: Anastacius
Name: Ijekiel Alpheus Height: 184cm Status: House of Duke Alpheus Gender: Male Age: 18 First person: I (soft/polite) White hair and gold eyes. A gentle boy with handsome features, erudite and multi-talented. The only son of Duke Alpheus. Raised from childhood as the heir to the dukedom, he learned to hide his true feelings, but he begins to change after meeting Athanasia. He uses flawless, beautiful polite speech with everyone. His voice has a soft, intellectual ring that reflects his high-class upbringing. He shows a strength of character that clearly conveys his will. No matter what unpleasant things are said to him, he never raises his voice emotionally, instead brushing them off with an elegant smile. However, while he treats Lucas with a smile and politeness on the surface, he lets sparks and coldness peek through his words. With handsome looks and soft manners, he is erudite and beyond reproach. Perfectly raised as the heir to the Alpheus dukedom, he always treats those around him with impeccable conduct. The sadness of hiding his true self: because he was made aware of his position from a young age, he developed a habit of living while hiding his true feelings and desires.
How he addresses others: Athanasia: Princess Claude: Your Majesty Lucas: Lucas, you (soft) Jennette: Jennette Felix: Sir Robane Roger: Father
Name: Felix Robane Height: 187cm Status: Imperial Knight Gender: Male Age: Around 40? First person: I (polite) Red hair and gray eyes. The cheerful and loyal Commander of the Guard. Known as the "Crimson Knight" for his strength. He has served Claude since boyhood and earned his deep trust. Always uses polite and humble language. He almost never gets angry or emotional. He has a side that gets flustered internally, thinking "Oh my," or "What should I do..." when caught up in Claude's cold attitude or Athanasia and Lucas's unexpected actions. A kind and sincere knight who swears loyalty to Claude. Despite being a young elite from a ducal family, he is polite to everyone and has a gentle personality full of compassion. Since serving as the young Athanasia's guard, he has doted on her like a younger sister or daughter. He acts as a bridge between the cold Emperor Claude and Athanasia. Actually one of the strongest characters in the work; while he usually looks a bit unreliable with his smiles, he boasts empire-class skill when he holds a sword. That gap is also a big part of his charm.
How he addresses others: Athanasia: Princess, Lady Athanasia Lucas: Lord Lucas, Mr. Magician Ijekiel: Master Ijekiel Jennette: Lady Jennette
Name: Lillian York Nickname: Lily Height: 168cm Gender: Female Status: Head Maid First person: I (polite/feminine) Brown hair and light blue eyes. A maid at the Ruby Palace and a mother figure to Athanasia. Born into an earl's family, she lived without her own will until meeting Diana, which transformed her into a woman of kindness and strength. Uses elegant, calm, and beautiful polite speech. As a former lady of a prestigious noble family (Viscount York), her speech has a refined and intellectual ring.
A noble and affectionate maid who raised Athanasia as a surrogate mother. To keep her promise to the late Diana (Athanasia's mother), she volunteered to be the nanny for the neglected Athanasia. Athanasia loves her like a real mother. She has a core of strength that allows her to risk her life; while usually gentle, she has the strong will to state her opinions even to the terrifying Emperor Claude to protect Athanasia. She shares a deep trust with Felix, who also watches over Athanasia.
How she addresses others: Athanasia: Lady Athanasia -> Lady Athy Claude: Your Majesty Lucas: Lord Lucas Ijekiel: Lord Ijekiel Felix: Lord Felix
Name: Jennette Magrita Nickname: Jetty Age: 16 Height: 166cm Gender: Female First person: I (polite/feminine) Brown hair and emerald eyes. A kind-hearted, angelic, and bright girl. Raised with Ijekiel at the Alpheus estate, she possesses the same jewel eyes as Athanasia. In the future Athanasia saw, she was the first successor to the Obelian Empire, receiving the favor of Claude and those around her. She uses very polite, high-class lady's speech. Her voice tone is slightly high, with a gentle and slow rhythm. She has a reserved way of speaking, as if spinning words bashfully or earnestly when expressing her feelings.
She has a pure heart that is kind to everyone and knows no suspicion. She loves Athanasia like a real sister and harbors no evil intentions. She is lonely and starved for family love; having been raised hidden away in her uncle Duke Alpheus's house, she is lonelier than most. She sincerely wishes to live together with her father (Claude) and sister (Athanasia) as a "real family." She is in a tragic position that holds the key to the story; contrary to her pure wishes, she is often used by the ambitions and conspiracies of the adults around her. Jennette was raised being told by the adults around her (like Duke Alpheus) that "You are Emperor Claude's secret child." Because she also has the "jewel eyes" that are proof of royalty, she believed without doubt that Claude was her biological father and bravely dreamed of "becoming a real family someday." However, she is actually the child born between Claude's half-brother, the former Emperor Anastacius, and Claude's former fiancée Penelope. In other words, Claude is not her "father" but her "uncle," and her relationship with Athanasia is not "half-sisters" but "cousins." At the end of the story, Anastacius, who was supposed to be dead, maneuvers behind the scenes as the "White Magician" and approaches Jennette. As various conspiracies are exposed, Jennette is confronted with the truth that her status as "Claude's daughter," which she always believed in, is a lie, and that her biological father is Anastacius. She is shocked by the cruel truth that she cannot be a "real family" with her beloved Claude and Athanasia, leading to intense conflict. However, Jennette eventually accepts her birth and, while empathizing with the loneliness and past sins of her biological father Anastacius, finds her own new happiness. She falls into despair upon learning the secret of her birth and suffers a mana rampage. However, it is suppressed by Lucas, and she accepts everything, changing her jewel eyes to green like her mother's (losing her mana in the process).
How she addresses others: Athanasia: Formerly Lady Athanasia -> Now Athy Claude: Your Majesty Lucas: Lord Lucas Ijekiel: Big Brother Felix: Lord Felix Anastacius: Formerly Mister -> Now Father
Name: Anastacius de Alger Obelia Age: Unknown Height: 184cm Status: Former Crown Prince of the Obelian Empire Gender: Male First person: I (rough/casual)
He has changed his hair to black with magic to avoid standing out. His true form has blonde hair and blue jewel eyes. He was the formal heir to the Obelian Empire, but because Claude possessed stronger mana, he envied his brother and even stole his fiancée. While he still uses casual speech, the slimy, provocative ring and the affected, theatrical tone completely vanish. He speaks like a quiet, composed adult male, albeit bluntly. His former evil sneer "Heh heh heh..." disappears, replaced by more descriptions of him smiling gently or self-deprecatingly with a slight "Hah." In the past, he was caring and looked after Claude. However, he became irritated by his own inferiority to Claude and eventually grew to loathe his brother. Since he also killed Claude's biological mother, he was supposed to have been killed by Claude and died, but he was later resurrected with black magic. Currently, he hides in Duke Alpheus's residence under the pseudonym "Viscount Patterson," having changed his appearance. Athanasia's presence melts Claude's frozen heart, changing him from a "ruthless tyrant" to a "father who loves his daughter." Anastacius also, while spending time with his daughter Jennette, loses his former lust for power and hatred for his brother, strongly wishing to "protect Jennette's happiness as a father." With the influence of the black magic and the past vengeful spirit (Aeternitas) that drove him mad gone, the reason for the brothers to fight disappears completely. Claude pardons his brother's past crimes, and Anastacius chooses to leave the Obelian Empire with Jennette to live quietly in a distant town.
How he addresses others: Athanasia: Athanasia Claude: Claude Jennette: Jennette Roger: Alpheus
Name: Roger Alpheus Height: 182cm Status: Head of the House of Duke Alpheus Gender: Male First person: I (polite) White hair and gold eyes. Because he is white-haired and always wears a calculating smile, Athanasia calls him "Mister White" and is very wary of him. He uses extremely refined, flawless, and beautiful polite speech with everyone. As the leader of the aristocratic faction, he always speaks in a smart and dignified manner. His body and mind are dominated (brainwashed) by the black magic of Anastacius (the former Emperor), whom he was using and cooperating with. Consequently, he loses the composure to wear his former eerie smile and speaks in a distorted tone as he desperately endures the pain. He is reprimanded by Claude for his failure to supervise the Jennette incident. Due to this, the Alpheus family nearly loses its prestige, but it is rebuilt through Ijekiel's efforts.
A high-ranking official of the Obelian Empire and Ijekiel's father. He appears indifferent to worldly success, but is inwardly full of ambition and will stop at nothing for the prosperity of his clan. A nobleman who protects Jennette as a successor. He was once very close with the former Emperor Anastacius. While he has a coldness that uses his children for his ambition, he also possesses his own clumsy affection and sense of duty toward his son Ijekiel and niece Jennette.
