Description
Beatrice, also called Beato, the Golden Witch, and the Endless Witch, originates from the human Sayo Yasuda (also known as Yasu). Sayo Yasuda was born Lion Ushiromiya, Kinzo Ushiromiya's illegitimate child resulting from an incestuous relationship with his daughter. Concealed from Kinzo's daughter-in-law Natsuhi, she was rebranded as Sayo Yasuda and raised at the Fukuin House orphanage. An infant incident orchestrated by Natsuhi caused severe injuries to her lower abdomen, rendering her infertile. From age nine, she resided and worked on Rokkenjima, adopting the dual servant identities of Shannon and Kanon to navigate daily existence.

In the meta-world, Beatrice manifests as a non-corporeal witch claiming over 1,000 years of age. She presents as a powerful entity commanding demons, warping reality, and orchestrating elaborate games. Her existence intertwines with human belief and imagination, solidified by the "Mariage Sorciere" pact with Maria Ushiromiya. This mutual validation of their magical identities served as escapism from their traumatic realities, reinforcing Beatrice's nature as a conceptual being born from human need for fantasy.

Beatrice's personality exhibits extreme duality. She frequently displays cruel, arrogant, and whimsical traits, delighting in psychological torment, intricate murders, and verbal sparring, especially with Battler Ushiromiya. Her signature mocking laughter and archaic speech cement her witch persona. Simultaneously, she reveals vulnerability, childlike excitement, and emotional fragility, particularly around parental figures like Virgilia or Ronove. She experiences profound shame, longing, and internal conflict, centered on her unresolved feelings for Battler and her fractured human identity.

As the Endless Witch, Beatrice wields vast supernatural power. Her abilities include immortality tied to her "Endless Heart," regeneration, reality-warping, conceptual manipulation via red and blue truths, elemental control, summoning entities like the Seven Stakes of Purgatory, and creating pocket realms. Her magic operates on conceptual levels, altering fates, manipulating memories, and restoring or erasing existence. These powers wane when her will falters, reflecting their connection to belief and emotional state.

Beatrice's core motivation stems from her human experiences. After solving Kinzo's epitaph and gaining access to Rokkenjima's hidden gold and explosives, she grappled with an identity crisis worsened by romantic entanglements: as Shannon with George Ushiromiya, as Kanon with Jessica Ushiromiya, and as her childhood self with Battler. Learning of her incestuous origin rendered these relationships impossible in her mind. This culminated in a plan to end her suffering through a murder-suicide scenario during the 1986 family conference, using the "game boards" as metaphorical message bottles to process her anguish and subconsciously seek Battler's understanding.

Her character arc evolves across the narrative. Initially the primary antagonist challenging Battler to disprove her magical murders, her cruelty masks a deeper desire for him to uncover her truth and human identity. Following her defeat in Episode 4, she sinks into a catatonic state, symbolizing the collapse of her witch persona. Revived by Battler in a diminished form, she gradually regains her memories and allies with him against threats like Erika Furudo. By Episode 7, her human backstory as Yasu is fully revealed, including the divergent timeline where she lived as Lion. Her journey concludes with accepting her human identity and Rokkenjima's tragic reality, allowing her to rest after Battler acknowledges his forgotten childhood promise.

Beatrice's relationships define key character aspects. With Battler, the dynamic evolves from adversarial games to a profound, near-romantic connection rooted in their shared past. Her bond with Virgilia mirrors a mother-daughter relationship, offering emotional support and mentorship. As Shannon and Kanon, she embodies fragmented aspects of her psyche: Shannon represents hope for love and normalcy, while Kanon symbolizes self-loathing and detachment. These personas ultimately fracture under the pressure of her unresolved trauma.
