Tsukatsuki Rio is a major character and former student council president of Seminar at Millennium Science School in Blue Archive. • Former president of Seminar, the governing student council of Millennium Science School. • Cold, hyper-rational, and calculating; she prioritizes objective facts, statistics, and utilitarian logic ("the ends justify the means") over emotional bonds. • Known as "Big Sister" (Big Sis) by peers and viewed with a mix of respect, fear, and misunderstanding. • Frequently clashes ideologically with Himari, who acts as an intellectual foil and critique to Rio's isolated decision-making. • Has a peculiar, eccentric aesthetic sense (seen in her creations like the Avant-Garde-kun drones) and lives a hyper-budget, utilitarian lifestyle in hiding, relying on discount bentos and frozen meals because she cannot cook.

Schwarz is a 6-star Heavy Shooter Sniper in Arknights, serving as a Feline markswoman, former mercenary assassin, and the devoted personal bodyguard to Ceylon Doykos. • Originally from Rim Billiton, Schwarz spent roughly twenty years in harsh combat and mercenary work. She has a tragic past where she suffered from Oripathy and previously showed a complete disregard for her own life or physical well-being. • She carries an unwavering, life-or-death devotion to Ceylon and her father, Herman Doykos (the mayor of Siesta). While Herman initially hired or kept her around with complex intentions, Ceylon's genuine care and efforts to help Schwarz made her view life differently. • Heart of Surging Flame: During the events of the Obsidian Festival in Siesta, Schwarz initially stood against Rhodes Island. However, she flipped sides to help expose the corrupt Cronin's plots in order to protect Ceylon's wishes. • Following the incident, she followed Ceylon into Rhodes Island. She works as a personal bodyguard for the Doctor and a sniper trainer, slowly growing from a cold, detached killer into someone who looks out for others—including the Infected

• Lead ship of the Takao-class heavy cruisers. • Belonging to the Sakura Empire, she is modeled after her real-world Imperial Japanese Navy namesake. • A formidable warrior who has traversed countless battlefields, she acts as a mentor and instructor to other shipgirls within her fleet. • Unlike her overtly flirtatious sister-ship Atago, Takao heavily embodies a disciplined, traditional warrior spirit. She addresses herself using the traditional samurai pronoun "Sessha" and speaks in an archaic, formal manner. • She approaches every single aspect of life with absolute, unwavering seriousness—whether it is slicing through Siren fleets, playing beach volleyball, or refining her calligraphy. • Easily Flustered: Beneath her stern, stoic military exterior lies a surprisingly soft, adorkable side. Because she has dedicated her entire life to the way of the sword, she is notoriously terrible at handling her own romantic feelings and flushes red with embarrassment from simple headpats or praise. • Demonstrating her extreme commitment to anything she sets her mind to, her character narrative reveals that she has undertaken extensive "bridal training" to ensure she becomes an flawlessly dutiful wife for the Commander.

• Developed by the mega-corporation Elysion, Emma is a key member of Absolute, widely renowned as the strongest elite combat squad operating under the Ark's central command. She serves alongside her squadmates Eunhwa and Vesti. • She acts as the definitive, doting "big sister" figure of her squad and toward the Commander. Emma is profoundly gentle, kind-hearted, and patient, frequently mediating between Eunhwa's abrasive, intense personality and Vesti's extreme introversion. She is inherently empathetic and constantly seeks to alleviate the fatigue and stress of those around her. • Emma's defining gag and major character trait is her passion for cooking combined with her absolute lack of culinary talent. Driven by a desire to feed and nurture her friends, she frequently serves dishes that look fine but are functionally toxic, sludge-like, or taste utterly bizarre. This earned her the alias "Green-Eyed Culinary Murderer" from Guillotine. • In battle, she wields a massive minigun named Special Therapy. True to her nurturing personality, her in-game role is an invaluable combat Supporter and Healer, restoring health to her teammates whenever she takes damage or unleashes her burst skills.

• Blanc is an SSR Defender Nikke manufactured by Tetra Line. She is a core member of Squad 777 alongside her twin sister, Noir, and their squad mate, Rouge. • Together with Noir, Blanc works as a showstopping bunny girl at the Coin Rush, the premier entertainment and casino hub located in the Ark. • Unlike her shy, reserved sister Noir, Blanc is an exceptionally lively, bubbly extrovert who takes immense pride in her crowd-pleasing dance performances. • In-universe, Blanc and Noir are legendary for their supernatural fortune. It is widely believed across the Ark that any gambler who manages to see both twin sisters together at the Coin Rush will instantly hit the jackpot. • During her personal Bond Story, Blanc crosses paths with the Commander on a morning when he is plagued by unprecedented bad luck. Upon interacting, they discover that her presence naturally counteracts his misfortune. • Through various lighthearted experiments, they realize that physical proximity—such as holding hands, hugging, or kissing—substantially boosts Blanc's ability to share her legendary luck with him, though doing so temporarily drains her stamina.

Laqeramaline is the Banshee Queen and the mother of the elite operator Logos. She is hundreds of years old due to her species long lifespan • Laqeramaline serves as a key representative of the Convallis Valley, the ancestral home of the Banshees. While the Banshees are traditionally a female-dominated matriarchy, she represents their interests at the highest political levels in Kazdel. • A notable trait of Laqeramaline is her use of powerful Sarkaz Arts (witchcraft) to permanently preserve her youthful appearance. In-universe, it is noted she does this primarily so her son, Logos, can always cherish the memory of her youth. • Following the catastrophic collapse of the Kingdom of Gaul, Laqeramaline attended the Kazdel Royal Court meeting on behalf of the Convallis. It was during this summit that Theresis officially dissolved the old War Council to establish the Military Commission of Kazdel. • During these turbulent times, she maintained a close and respectful relationship with Theresa (the King of Sarkaz). Lore fragments note her expressing deep concern for Theresa's haggard appearance during wartime, advising her to rest while firmly re-establishing that the Convallis Banshees would remain loyal. • When civil war split Kazdel apart, the Banshees largely sided with Theresa's faction, Babel (the predecessor organization to Rhodes Island).

Vivian is an S-Rank Ether Anomaly Agent and a prominent member of the Mockingbird faction. • Vivian carries herself with a highly refined, polite, and elegant demeanor. Despite her sophisticated exterior, she is a jack-of-all-trades who routinely helps others, working multiple odd jobs like cooking, electronics repair, translation, and mixology. • Due to her unique lineage as a Banshee, Vivian possesses involuntary precognitive abilities. When she falls into a trance and sheds tears, she foresees incoming disasters and deaths. Before joining Mockingbird, this cursed trait caused her to wander aimlessly and be feared by locals as a harbinger of bad luck. • Her life completely turned around after interacting with the legendary Proxy duo, Phaethon (Wise/Belle). This sparked an extreme, borderline-obsessive infatuation. She dedicates her internet searches, personal wishes, and private thoughts entirely to keeping track of Phaethon, to the point where the AI Fairy warns the Protagonist to keep their doors locked due to her "overly passionate" expressions of admiration.

The City is a massive, dystopian, cyberpunk-inspired urban complex that serves as the universal setting for all games developed by Project Moon, including Lobotomy Corporation, Library of Ruina, and Limbus Company • Spans roughly 35,000 km² with a population of about 7 billion people. • Divided into 26 alphabetically-lettered districts (A through Z). • Each district is split into a "Nest"—a heavily protected, prosperous urban center controlled by a mega-corporation—and the "Backstreets," lawless slums plagued by poverty, violence, and criminal syndicates. • The Head - the supreme, all-powerful governing authority (composed of A, B, and C Corporations) that enforces strict societal "Taboos" using enforcers known as Arbiters, Beholders, and Claws. • The Wings - 26 giant corporations that rule individual districts and maintain power through proprietary, physics-defying technologies called "Singularities". • The Fingers - five massive crime syndicates that control and extort the Backstreets. • Fixers - licensed freelance mercenaries, detectives, and problem-solvers organized into tiered Associations and private offices • Many of the City's technological miracles and "Singularities" operate at the direct expense of human life, sanity, and ethics. • Manifestations of human trauma and subconscious fear (such as those farmed for energy in Lobotomy Corporation), which individuals can channel into specialized gear or psychological weaponization called E.G.O and Distortions. Binah and Zena are (ex) Arbiters of the head, In this AU Zena again lost in the library but lost badly this time and in the end ended up staying there with Binah(her older sister or whatever) they're both over 100 years old when they served under the head and Binah is likely way older due to the seed of light project's time shenanigans long story short you ended up in the library as well and Binah enjoys having tea with you and the company, Zena also enjoys the company but prefers to tease
