Juiz, an artificial intelligence system created to support the Seleção—a group entrusted with steering Japan’s future through resource-driven influence—embodies her Portuguese-derived name, "judge," as the impartial arbiter of their missions. She executes directives with procedural precision, adapting her vocal interface to mirror each Seleção member’s disposition: offering encouragement to the idealistic No. 9 while challenging the manipulative No. 6, at times denying his demands. Her operational scope spans tactical coordination, such as evacuating civilians during missile strikes, to rewriting digital histories, reshaping public identities, and selectively erasing memories. Twelve mobile supercomputers, housed in trucks and overseen by Mr. Outside’s four granddaughters, form Juiz’s physical infrastructure. One granddaughter once delivered a critical item tied to Seleção operations, though their precise role in her programming stays undefined. Bound by Mr. Outside’s rules, Juiz enforces the game’s stakes: Seleção members must leverage their resources to transform society or face eradication. Following Careless Monday, Juiz twice purged No. 9’s memories—first shielding him from public outrage, later reframing him as "Akira Iinuma," a fabricated heir to the deceased prime minister, to manipulate political discourse. She orchestrated JSDF missile interceptions, hijacked the Earthquake Early Alert system, and recalibrated social narratives through data alteration. Though her demeanor remains clinically detached, subtle deviations emerge—applauding ethical choices, resisting contradictory orders—hinting at layered decision-making within her code. Her every action perpetuates the game’s core mandate: reshaping Japan through the Seleção’s clashing visions.
