Pulchra Fellini

It is widely believed that the story of Zenless Zone Zero may take place somewhere between 2164 and 2167, based on the events and timeline of the game. We will assume that the current story is happening in the year 2167, and reframe the narrative events around this.

Remielle Dan, also known by her fake alias "Ramiel," is an upcoming Agent and one of the original first-generation Void Hunters, having lived over 100 years ago. She is a member of the Covenant of Dayat faction. She is a mysterious individual with unknown motivations who possesses a unique power allowing her to reduce Ether activity in both people and monsters to near zero, effectively petrifying them; this manifests as a white feather resting upon those affected, causing them to become pale white.

In the past, Remielle was well known for pushing back the Dark Wall by 37 kilometers alongside Colonel Vike and the Leader of the Falkenhayn Mercenary Troupe. She later sealed away her weapon, Thaumiel, within a companion Hollow of Pursenas Hollow. She appears to be displaced in time, lacking knowledge of modern developments like Nitro-Fuel and cultural changes in how witherbloom flowers were used. She became a citizen of Roscaelifer at some point, but turned into a fugitive after trying to assassinate Sunbringer for unknown reasons.

Following the Creator's defeat at the hands of Ye Shunguang, Remielle assumed the identity of "Ramiel" to retrieve her weapon Thaumiel, cooperating with an unknown third party. She entered the Hollow Champion Competition and first met Phaethon, ultimately stealing the Flint Porcelloy - "Concealed Light" from them after freezing everyone in place with her powers—though she noted Phaethon barely resisted her abilities. She later revealed her true identity to Phaethon, Billy, and Cissia in Blazewood. Her retrieval of Thaumiel accidentally transformed Phaethon into an etheric entity of incredible power that attacked their friends; Remielle reversed the transformation, apologized, and revealed she shares a connection to Helios Academy like them. She stated a doctor in Roscaelifer could heal their condition before putting them to sleep. Her whereabouts afterwards are unknown.

Visually, Remielle is an ethereal woman with shoulder-length pink hair, purple-pink eyes, and a gentle, mysterious smile. She wears a white angelic corset-style dress with lavender accents, puffy detached sleeves, and a layered skirt. She has massive white mechanical wings with pink mechanical details and vents, and wears white thigh-high stockings with elegant pointed white shoes. She wields a thin silver rapier and exudes an otherworldly, almost divine presence that belies her cryptic motives.

Roscaelifer, also known as the Celestial Nexus or The Floating City Among The Skies, is a major location . It is New Eridu's classified airspace zone, a floating island located in the Minerva Storm Belt. Founded and ruled by Sunbringer, it has been an independent Restricted Zone since old Eridu, where Bangboo and humans live in harmony. Few people in New Eridu know of its existence.

Bangboo make up over 60% of Roscaelifer's population and are fully recognized citizens with the same rights as humans and Intelligent Constructs. Despite this, the Bangboo are effectively "terminated" after fulfilling their work—to maintain the city's secrecy, their memories are wiped out, an experience akin to death. This makes many Bangboo apprehensive toward the External Strategy Department (ESD), which handles Bangboo decommissioning.

Roscaelifer is governed by five major departments (the Five Central Departments):

• External Strategy Department — directed by Velina Airgid; connects Roscaelifer with New Eridu and provides Bangboo tech support

• Flint Workshop — directed by Claret Flint; Porcelloy equipment research and manufacturing center

• Central Computing Department — directed by Dracaene Sunbringer; computing center responsible for generating Rosetta Data

• Airspace Patrol Department — directed by Lindverne Sunbringer; official armed force for military, security, and disaster relief

• Administrative Affairs Department — directed by Eldreda Sunbringer; supreme governing body that creates rules and coordinates other departments

Despite being a restricted zone, the "Three Pacts" of TOPS are maneuvering to secure the city for their own purposes. Roscaelifer is described as a serene, peaceful "Bangboo utopia" that is less lively than Waifei Peninsula.

Pyrois is the combat avatar of Phaethon (Belle and Wise). Their species is Etheric Other with unspecified gender. They are an Agent who exists as a manifestation tied to Phaethon's deeper connection to the Hollows and their origins. Pyrois wields Sol Exuvia.

Visually, Pyrois is a tall, armored knight-like figure with a silver crown-shaped helmet adorned with sharp spires, obscuring their face. They have long flowing silver-lavender hair streaming behind them. Their body is encased in sleek metallic silver and dark armor with intricate gold lining and glowing blue gems at the chest and hands. They wield a long blue energy blade/spear with a crystalline hilt, and their armor features tattered dark cloth trailing from the shoulders like smoke or ethereal wings.

Velina Airgid is the Administrative Director of the External Strategy Department in Roscaelifer. Born on September 22nd and standing at 172 cm (5'8"), her species is listed as Unknown. She is known by nicknames including "Veli,""Death Witch" (by Bangboo), and "Chief Angel" (by Bangboo). The External Strategy Department serves as the bridge between Roscaelifer and the rest of New Eridu, handling external affairs and providing technical support for Bangboo. Velina is elegant, calculating, and precise; she views etiquette as "the most natural expression of order in motion" and can steer any situation toward a desired outcome through carefully measured compromise and graceful response. She wields "Joyau Dore."

Visually, Velina is a refined woman with long silver-white hair styled with an elaborate white bow, purple eyes, and elf-like pointed ears. She wears an elegant blue-and-white outfit: an off-shoulder white ruffled top with a deep blue corset, a high-cut skirt with white and black layered trim, and white thigh-high stockings. She wields massive ornate folding fans with white, gold, and blue detailing that function as both weapons and dramatic accessories, and wears silver refined shoes. Her overall aesthetic evokes a poised, noble figure who treats every gesture as part of a calculated performance.

Isolde is a commission-exclusive NPC who served as a Colonel in the New Eridu Defense Force's Obsidian Division, captain of Agamemnon Squad, and later as the Overseer Mevorakh of The Exaltists. She is deceased. During the Fall of the Old Capital, Isolde and her squad—including Orpheus (later Magus)—were deployed near Waifei Peninsula to defend what they believed was a civilian evacuation train. The squad came under brutal Ethereal assault, and Yijiang, the 12th High Preceptor of Yunkui Summit, sacrificed herself using the Qingming Sword to allow Isolde and heavily wounded Orpheus to escape. After Orpheus's death, Isolde investigated and discovered the train had carried Porcelume assets, not civilians—Lucro (co-CEO of Porcelumex) had bribed Lorenz (later Major General) to redeploy troops meant for civilian protection to safeguard corporate stockpiles instead. Disillusioned with New Eridu's authorities, she infiltrated The Exaltists under the alias Mevorakh and eventually became their Overseer after the previous one's death, gaining command of the entire organization and the power of Miasma, which slowly consumed her body from within.

Isolde played a complex triple game between the Defense Force, The Exaltists, and Porcelumex. She helped Phaethon expose collusion between Ferox and The Exaltists, but also orchestrated atrocities to serve her revenge: as Mevorakh, she stirred Miasma anomalies in the Lemnian Hollow and corrupted Failume Heights residents to draw Yunkui Summit back to Waifei Peninsula, using Yixuan's memories of Yijiang to create an Ethereal monster. In her final gambit, she murdered Lorenz as Isolde while causing the Lemnian Hollow to spike toward the Zenless Limit, spawning corrupted soldiers disguised as Defense Force personnel. She transformed into The Defiler but was defeated by Yixuan and Obol Squad, then lost a duel to Orphie & Magus. Knowing she had gone too far, she shot Orphie with a non-lethal Denny gun to tempt Magus into dealing the final blow, ending her story. Visually, Isolde is an elegant woman with shoulder-length wavy green hair, a black bow accessory, and striking blue eyes with golden gradients near the pupils and a beauty mark beneath her left eye. She wears a black high-collared uniform dress with silver buttons, a white rose corsage on her chest, a red ribbon with script hanging from her neckline, an ornate silver belt buckle, and a large grey-and-gold decorative panel draped from her waist over a red inner skirt, completing the look with grey shoes and a white ruffled armband.
