Who Made Me a Princess Characters: Athy, Claude, and Cast

Who Made Me a Princess characters split into two groups that rarely overlap cleanly: the people Athanasia is related to by blood, and the people orbiting her because of a novel neither she nor they asked to be trapped inside. Knowing which is which changes how most scenes read.

TL;DR: Who Made Me a Princess characters, sourced from the character wiki's episode data: Athanasia (the reincarnated protagonist), Claude (her biological father, not just a cold guardian), Lucas (the Black Tower magician who becomes her husband), and Jennette Margarita (her cousin, not her sister, despite how the story frames it early on). The full Obelian cast below covers where each name actually comes from.

Who Made Me a Princess Character Guide: Key Takeaways

• Athanasia de Alger Obelia is the reincarnated protagonist; Claude is her biological father, not an adoptive or step-relationship
• Jennette Margarita is Athanasia's first cousin, daughter of Claude's half-brother Anastacius, not Claude's second daughter
• Lucas, the Black Tower's magician, starts as Athanasia's stabilizing companion and becomes the story's romantic lead
• Anastacius de Alger Obelia, Claude's ousted half-brother, is the series' main antagonist, operating under disguise for most of the story
• Diana, Athanasia's late mother, and Penelope Judith, Jennette's late mother, both died before the current timeline begins, and their history explains most of the cast's present-day grudges

Overview: Why This Cast Needs Untangling

The premise sounds simple: a woman who read a novel called "The Lovely Princess" wakes up as its tragic first princess, Athanasia, and has to avoid the execution her father orders in the original story. What makes the cast confusing is that almost everyone significant is connected to that novel's plot in a way that isn't obvious from a first read.

Claude, the emperor, is Athanasia's real father, full stop, but the series spends its early chapters making him read as distant enough that some readers assume otherwise. Jennette, introduced as "the beloved princess" of the novel-within-the-story, gets described early on in ways that make her sound like Claude's other daughter. She isn't. Her actual father is Anastacius, Claude's half-brother and the man who used to sit on the throne before Claude took it from him. That single correction, Jennette is a cousin, not a sibling, resolves more confusion about this cast than anything else in it.

Who Made Me a Princess Characters: The Obelian Royal Family

Athanasia de Alger Obelia is the protagonist and current Crown Princess. A modern woman who dies and wakes up as infant Athanasia inside the novel she read, she knows her fate: in the original story, her own father executes her after she's falsely accused of poisoning her cousin Jennette. Her actual goal across all 135 chapters isn't romance, it's making Claude genuinely love her before that fate can repeat. She develops real magic later in the story, tied to time and mana, powerful enough to have reset Claude's memory once already.

Claude de Alger Obelia is the reigning Emperor of Obelia and Athanasia's biological father. He took the throne from his half-brother Anastacius and used black magic to strip away his own emotions after the woman he loved, Diana, died giving birth to their daughter. His coldness toward Athanasia in the early chapters is grief redirected, not indifference to the relationship itself; the character wiki's own relationships data confirms Diana is listed as Athanasia's mother and Claude's lover, not a rumor the story leaves ambiguous.

Jennette Margarita is Athanasia's first cousin and the protagonist of the novel-within-the-story, "The Lovely Princess." Her biological father is Anastacius; her mother, Penelope Judith, died giving birth to her. Raised in hiding from her real parentage, Jennette believes for most of the story that family means unconditional love, a belief the plot uses against her repeatedly. She isn't cruel or a schemer; she's naive in a way the actual schemers around her exploit.

Anastacius de Alger Obelia is Claude's older half-brother, the empire's former emperor, and the series' main antagonist. Ousted from the throne and left for dead, he returns disguised, using a stolen appearance to move through the empire undetected while working to reclaim power. He's Jennette's biological father, though he keeps that fact from her for most of the story, and his relationship with his own daughter is the closest thing his character has to a soft spot.

Who Made Me a Princess Characters: The Magicians

Lucas is the Magician of the Black Tower, a two-thousand-plus-year-old sorcerer who first appears stabilizing Athanasia's dangerously overflowing magic. Outwardly composed and well-mannered in public, he's privately ruthless, vain, and detached from ordinary human values in a way that tracks with having lived for centuries. He starts the story as Athanasia's assigned companion and becomes her romantic lead as the series continues; the character wiki lists him as her eventual husband in its relationships data, which is about as far as a manhwa fan wiki commits to spoiling an ending.

Lucas's arc is the single most divisive element of the fandom's reaction to the back half of the series. Readers who came for the Athanasia/Claude relationship sometimes find his introduction shifts the story's center of gravity; readers who wanted a clear romantic lead often consider his arc the payoff the earlier chapters were building toward.

Who Made Me a Princess Characters: House Alpheus and the Nobility

Ijekiel Alpheus is the oldest son of House Alpheus and, in the original novel, the male lead who ends up engaged to Jennette. In the manhwa's actual timeline, he's a gentle, composed young noble who falls for Athanasia in both versions of events. He's popular in high society, nicknamed the "Lord of Soft Charisma," and turns out to be sharper than his easygoing manner suggests when the plot needs him to solve a problem.

Roger Alpheus is Ijekiel's father, the head of House Alpheus, and an imperial advisor with real political ambition. He's patient and calculating rather than openly scheming, and his household ends up sheltering more of the story's hidden relationships than he initially realizes.

Penelope Judith is Jennette's late biological mother. Once engaged to Claude, she broke off that engagement to pursue Anastacius, the man she believed would actually inherit the throne. Ambitious and self-interested by the wiki's own character summary, she died giving birth to Jennette after Anastacius's fall from power forced her into hiding at House Alpheus.

Who Made Me a Princess Characters: The Obelian Commoners

Diana is Athanasia's late biological mother, a dancer from the province of Siodonna who caught Claude's attention at an imperial banquet. Free-spirited and direct in a way the rest of the imperial court isn't, she chose to carry Athanasia to term despite the medical risk, and named her daughter "Athanasia" (meaning immortality) in defiance of a royal naming tradition reserved for official heirs. Her death is the specific wound Claude's early coldness comes from.

Step-by-Step

The character wiki's episode-debut data lines up into the order this cast actually appears on the page, which is a useful check against assuming everyone shows up in chapter 1 together.

1. Athanasia and Claude: Episode 1. Both open the story together, though Claude's introduction happens through Athanasia's memory of the novel before he appears in the present timeline.

2. Ijekiel Alpheus: mentioned Episode 1, first full appearance Episode 21. He's referenced early as the novel's male lead before the manhwa actually brings him on-page.

3. Roger Alpheus: Episode 3. Ijekiel's father appears early, establishing House Alpheus as a recurring location.

4. Jennette Margarita: mentioned Episode 1, first full appearance Episode 22. Like Ijekiel, she's referenced through the novel's plot before the manhwa gives her a present-timeline scene.

5. Lucas: Episode 17. He's introduced stabilizing Athanasia's overflowing magic, the event that puts him in her life permanently.

6. Anastacius de Alger Obelia and Penelope Judith: both Episode 23. Their shared backstory episode is where the manhwa reveals Jennette's real parentage.

7. Diana: mentioned from Episode 2, full appearance in flashback at Episode 99. Athanasia's mother is present in memory long before the story shows her directly.

Tips for Keeping This Cast Straight

1. Track "cousin," not "sister," for Jennette. The novel-within-the-story frames Jennette as Athanasia's sister-coded rival. The manhwa's actual family tree makes her Athanasia's first cousin through Anastacius. Holding onto that one correction clears up most of the early-chapter confusion.

2. Remember Claude and Anastacius are brothers, not father and son. Their age gap and formal titles (Emperor, former Emperor) can read like a generational relationship. They're half-brothers.

3. Watch which characters are already dead when the story starts. Diana and Penelope Judith are both deceased before the current timeline opens; everything about them arrives through flashback and other characters' memories, not present-tense scenes.

4. Don't assume Lucas is comic relief because of his child-sized disguise form. His actual age and power level are enormous; the youthful appearance is a mana-conservation choice, not a reflection of his role in the plot.

Frequently Asked Questions

Who are the main characters in Who Made Me a Princess?

Athanasia (the protagonist), Claude (her father), Lucas (the magician who becomes her husband), and Jennette Margarita (her cousin and the novel's original heroine) form the core cast the rest of the story orbits.

Is Claude really Athanasia's biological father?

Yes. Confirmed directly in the character wiki's relationships data: Diana is listed as Athanasia's mother and Claude's lover. His early distance from Athanasia is grief, not doubt about the relationship.

No. Jennette's biological father is Anastacius, Claude's half-brother. She's Athanasia's first cousin, not a second daughter of Claude's, even though the novel-within-the-story's framing makes that mix-up an easy one to make.

Who is Lucas to Athanasia?

The Black Tower's magician, initially assigned to stabilize her magic, who becomes the series' romantic lead and, per the character wiki, her eventual husband.

Who is the villain in Who Made Me a Princess?

Anastacius de Alger Obelia, the ousted former emperor and Claude's half-brother, working in disguise to reclaim the throne he lost.
