Elicia appears mysteriously before the Subaru guild, revealing startling awareness of Asahi's presence within the virtual world Re'Union despite Asahi's known death. This enigmatic girl, recognized by her light purple hair often obscuring her left eye and consistent attire, delivers early warnings to Haruto about targeting and discloses knowledge of Satsuki's involvement, positioning herself as a situational ally in critical moments.

She wields a specialized bow capable of piercing enemies and forcibly extracting their senses, temporarily nullifying their abilities. Elicia employs this weapon in attempts to intervene in Asahi's circumstances, notably trying to seal Asahi's senses to halt further experimentation—though the outcome remains unknown.

Her background includes a six-year period surveilling Asahi alongside Clive, suggesting a protective or observational role. Elicia's existence embodies the celestial motif of the Pleiades star cluster as its seventh star, visible only to select individuals. This unique trait explains conflicting perceptions of Subaru's membership—appearing as six members to some, seven to others.

Her narrative arc culminates in the revelation that she is the seventh member of Subaru. This late integration resolves lingering ambiguities surrounding her identity and solidifies her persistent presence within the guild's endeavors.
