Estelle

Biodata

Power Progression

Background / History

Estelle grew up at Count Bain’s Estate with her parents and younger sister, Elusa. The sisters were close: Elusa followed her around like a shadow and repeatedly called her “big sister” 31.

According to Eros’s recollection, Estelle married Duke Renka at thirteen, gave birth to Wendy at fourteen, and had Eros at sixteen. Her father arranged the marriage in exchange for resources, and she had not even seen her future husband beforehand. She initially resented her father, but the kindness of her new household helped her accept the marriage; she said that resentment lasted only through the first year 24.

Distance and raising her children kept Estelle from returning to her family home for roughly twenty years. During that separation, she continued writing to Elusa, unaware that her sister had disappeared. Their mother arranged substitute replies that became progressively shorter and slower, leading Estelle to believe their relationship had simply grown distant 24 31.

Appearance

Estelle is described as tall and exceptionally beautiful, with a graceful bearing and a normally gentle expression 2 6.

• Hair: Long, platinum-blond hair falling over her shoulders 2.
• Eyes: Clear and gentle, repeatedly compared to water; no eye color is specified 2 8 13.
• Clothing: Wears a billowing white dress at her introduction 2.
• Build: Slender arms and a delicate figure, despite being able to lift Wendy effortlessly with one arm 3 33.

Personality

Estelle is openly affectionate toward Eros, praising him, comforting him after frightening experiences, and singing lullabies at his request even after he reaches adulthood. She accepts his unusual remarks with familiarity and takes pleasure in his enjoyment of her singing 2 13 16 19.

Her gentleness does not prevent her from being strict. She reprimands Wendy for skipping lessons, bullying Eros, and neglecting proper posture, expecting her older daughter to set an example. She treats Duke Renka’s children by other women without cruelty, but maintains an emotional distance from them 2 3 29 30.

Protectiveness sometimes leads her to restrict her children’s choices: she conceals Eros’s early occult memories and refuses to let him accompany her into the Sin Domain. After he injures himself healing her, she tearfully begs him never to take such a risk again 6 32 33.

• The Countess — Her mother, to whom she was especially close before marriage. Their reunion is emotional, though Estelle learns that her mother arranged false replies to her letters to Elusa 24 31.
• Elusa — Her younger sister. Guilt over unknowingly leaving Elusa missing for years drives Estelle to search the Sin Domain herself 31 32.
• Mishuel and Sivier — Duke Renka’s children by another mother. They address Estelle respectfully as “madam”; Mishuel reports the family’s Imperial Capital affairs to her 30.

Story Role / Major Arcs

Eros’s Introduction to the Occult

Estelle initially protects Eros by suppressing his premature knowledge of the supernatural. Once he comes of age, she attends his bloodline baptism and watches proudly alongside Duke Renka. When Eros vanishes from the formation, she tries to approach despite being pushed back by the Silver-White Moon Wheel, stopping only after Renka reassures her 6 8 10.

After the Book of the Night ritual leaves Eros unconscious, Estelle carries him out and watches over him during his seven-day sleep. On waking, he tests Divine Art: Prayer of Life on her, removing her accumulated exhaustion but exhausting his own Spirit and fainting again 12 13.

Journey to the Imperial Capital

When Eros seeks permission to experience the outside world, Estelle volunteers to accompany him, citing her Sequence 6 strength and family connections in the capital. The elders approve and arrange additional companions and sealed artifacts 22 24.

She travels with Eros and Wendy by airship and private steam train to Intiles, where Mishuel and Sivier meet them. The following morning, she takes her children to Count Bain’s Estate for her first family reunion in roughly twenty years 26 29 30 31.

Search for Elusa

At the reunion, Estelle learns that Elusa disappeared in the Mount Matigold Range’s Sin Domain during the third year after her marriage. Church searches found no way to retrieve her, though the family believes she remains alive inside 31.

Estelle persuades her father to let her search, relying on her rank and sealed artifacts. She refuses Eros’s request to join her: the Church’s compensation permits the family to send only one searcher into the domain at a time 32.

She returns pale and barely conscious before collapsing at home. Barbara identifies that one-fifth of her soul has been forcibly erased. Eros repairs it with Divine Art: Hymn of Life, suffering backlash that leaves him bedridden for a month 32 33.

Although Estelle recovers, she cannot remember the events surrounding the injury. She recalls apparently glimpsing Elusa and activating the Spirit World Gate to escape. Recognizing that her current strength is insufficient, she postpones the search without abandoning her sister 33 34.
