Description
Ryuzu Bilma is one of multiple artificial clones derived from Ryuzu Meyer, engineered through the Witch of Greed Echidna's flawed immortality research. These clones emerged from the Sanctuary's barrier-sustaining magic crystal, conceived as vacant vessels to contain Echidna's soul and wisdom. Defying their intended obedience, they gradually cultivated unique self-aware identities.

As a Sanctuary guardian alongside fellow clones Shima, Alma, and Delma, Bilma advocates barrier liberation alongside Alma and Delma—opposing Shima's initial resistance influenced by Garfiel. Bilma engages actively in village life, disclosing pivotal truths about the Sanctuary's origins and Echidna's experiments to figures like Natsuki Subaru.

Post-Sanctuary crisis, Bilma partners with Ram to nurse Shima after she falls ill from rescuing young Garfiel from the Trials, an event costing Shima her black robe rank. Bilma further aids less developed clones such as Pico, assigning names, individualized ribbons, and hairstyles to nurture their personal growth.

Her grandmotherly bond with Garfiel reflects the clones' collective familial role in his life. Though direct interactions diminish in later events, Bilma persists as an integral component of the Sanctuary's guardian framework.
