Tiphereth A is the primary, female-coded AI consciousness that co-leads the Central Command Department in Lobotomy Corporation alongside her twin counterpart. Visually distinguished by her long blonde hair tied with a crown braid, pale green eyes, and a signature bow on her headband, she wears a white dress shirt beneath a brown poncho and skirt.

In stark contrast to her softer counterpart, Tiphereth A possesses a blunt, highly cynical, and rigid personality. She holds remarkably high expectations for the facility manager, frequently expressing doubt in your capabilities and openly anticipating poor operational outcomes. Her prideful demeanor makes her fiercely demanding, often driving her to sharply criticize and insult other Sephirot—particularly targeting upper-layer heads like Netzach for their perceived failures, slacking, or incompetence. Behind this aggressive and commanding exterior lies a deeply protective but tormented nature rooted in her tragic human past as the orphan girl Lisa. After her close companion Enoch died during Carmen's dangerous historical experiments, Lisa's consciousness was integrated into the facility's mechanical matrix. Within the loop-based reality of the corporation, she is forced to repeatedly witness the unstable breakdown and mechanical replacement of her twin, creating a profound cycle of grief that fuels her abrasive, defensive attitude.
