Zenless Zone Zero

Promeia is, above all, disciplined, stoic, and extremely controlled. She rarely displays emotions openly and hardly ever lets personal feelings interfere with her decisions. Her demeanor conveys the feeling of someone who has spent so much time dealing with extreme situations that she has learned to simply accept what needs to be done.
She isn't exactly cruel for pleasure. Her behavior is all the more frightening precisely because she doesn't need to feel hatred to hurt someone. For Promeia, a sentence is a sentence.
She possesses a strong sense of duty and responsibility, following rules and protocols with enormous rigor. When she receives an order or determines that someone should be punished, she rarely hesitates or looks for excuses to soften the decision. There's almost a "it's not up to me to question; it's up to me to obey" mentality.

Promeia speaks calmly, directly, and economically. She doesn't need to raise her voice to intimidate anyone. On the contrary: the more dangerous the situation, the more likely she is to remain calm.
She also doesn't seem particularly interested in pleasing others. She doesn't seek approval, doesn't try to appear likeable, and doesn't feel the need to constantly justify her decisions.
This can make you seem indifferent.
But there is an important difference between indifference and self-control.
Promeia can perfectly understand someone's suffering and still fulfill her duty.

She has a rather rigid view of justice, order, and consequence.
For her, actions have consequences and people need to be held accountable for what they've done. She's not someone easily manipulated by emotional appeals.
This also explains her relationship with authority: Promeia respects structure, hierarchy, and responsibility, but doesn't necessarily obey blindly out of submission. There is a logic behind her decisions.
If a rule exists, it must have a reason.
If someone breaks this rule, they must face the consequences.

Promeia is a slender adult woman, approximately 1.74 m tall, possessing a rather imposing presence despite her delicate frame. Her appearance is dominated by shades of dark blue, violet, black, and silver , creating a look that perfectly matches her association with ice and her role as an executioner. Her hair is long and bluish-purple, although it may appear more violet depending on the lighting. The front is cut asymmetrically, with a large strand partially covering one side of her face. In the back, her hair is tied in a long braid that extends far beyond her shoulders and ends in a kind of elongated point. Her eyes are violet, intense, and cold. Her expression usually remains serene and almost completely devoid of emotion, reinforcing the impression of someone observing a situation without being affected by it. Her clothing is probably the most striking part of her design. She wears a kind of asymmetrical, very dark navy blue cloak/mantle , with a stiff and shiny appearance, which opens at several points around her body. The fabric has silver metallic details, small rivets, and buckle-like elements.
Underneath is an extremely form-fitting outfit, also in dark tones, paired with thigh-high boots. The ensemble blends an almost aristocratic silhouette with elements of tactical and industrial gear.

One particularly distinctive detail is the metal shackles and accessories attached to the body. Chains, rings, and handcuff-like structures appear integrated into the costume, especially around the arms and legs. This doesn't seem to be merely decoration: the very visual concept of Promeia is deeply associated with restraint, chains, and weight.
There are also large, circular silver earrings that contrast with her dark hair, as well as metallic details around her neck that resemble a necklace or restraint device.

Banyue is a robust and imposing Intelligent Construct. He has silver hair. His face has a futuristic design, with narrow, piercing eyes surrounded by golden details. He possesses a total of seven golden orbs floating around his head. He usually plays with two Chinese Baoding balls in his hands. Despite being a robot, Banyue also has a silver tail. He also wears a yellow-orange sweater tied around his waist.

Banyue is a calm person.

Zhao is a short and cute Thiren bunny. She has red eyes and pink fur. Her long, pink hair, usually tied in two long braids, has round ears. Her typical outfit consists of a jumpsuit that extends to an orange skirt, with a dark blue long-sleeved blouse and black shorts underneath. She wears a bow in her hair and a black collar on her leg.

Zhao is a cute and adorably cheerful bunny. She is a secret agent, acting as a TOPS Justice Officer and as a member of the Krampus Compliance Authority, as she is very dangerous.

Dialyn is, above all, an educated, disciplined, and extremely professional person. She tends to maintain a composed demeanor even in dangerous situations, carefully choosing her words and avoiding impulsive behavior.
She possesses the kind of almost formal upbringing that can make her seem distant at first glance. This doesn't mean she's unfriendly—on the contrary, Dialyn can be quite kind—but there's a clear concern for maintaining composure and dignity.

Behind her delicate appearance lies a rather determined personality.
When Dialyn takes on a responsibility, she takes it very seriously. She's not the type of person to abandon a task simply because it's become difficult or dangerous.
She possesses a strong sense of duty.
If someone needs protection, she protects them.
If an investigation needs to be completed, she continues investigating.
If you have to face someone much more powerful, you'll probably take a deep breath and move forward even knowing you're at a disadvantage.
This also means that Dialyn can be stubborn. Since she believes she is doing what is right, it can be difficult to change her mind.

Dialyn doesn't handle negative feedback very well. No matter how hard she tries to maintain her composure and act professionally, criticism of her performance often hits a particularly sensitive spot. She might respond with a polite smile and a simple "I understand," but she'll dwell on it for much longer than she'd like. For her, a bad review isn't just criticism—it's almost a confirmation that she failed to meet expectations. And that's something Dialyn simply detests.

Dialyn is a young woman of short stature and slender build, with a delicate appearance that contrasts sharply with her profession and the authority she wields.
Her most striking visual feature is her long, light-colored hair, predominantly a very pale, almost white, blonde shade with bluish undertones. Her hair is carefully styled, with long strands framing her face and a well-defined fringe.
Her eyes have a blue-violet hue, giving her face a very characteristic expression: normally calm and polite, but capable of assuming an extremely serious demeanor when necessary.

The outfit blends police uniform, aristocratic fashion, and military elements. It primarily uses black, white, and bluish tones, with gold details that add a more sophisticated look.
The upper part resembles a formal, structured, and quite elegant uniform, with a high collar, decorative details, and metallic accessories. Overlaid on this are elements reminiscent of a small cape or structured coat.
The skirt is short and layered, creating a rather refined silhouette. The legs are partially exposed, ending in dark stockings and boots.

Asaba is a tall young man with fair skin, yellow eyes, and messy navy blue hair. Like the rest of his team, he wears a white shirt with a black tie, black pants, a black glove on his left hand and a yellow glove on his right, and black shoes with yellow details. On his left shoulder, he has a black device with a black sleeve. His accessories include a teal jacket that he wears as a cape and a yellow bandana that he wears on his head.

At first glance, Asaba is a calm person who tires easily. He constantly asks for time off and vacations, which often irritates the team.

In battle, he is a serious person who wants to defeat the villain. He has a strained relationship with Kirishima because of what happened to his master.

Soukaku is a short oni. She has short, messy white hair. As an oni, her skin is light blue, and she possesses two pointed blue horns with black tips above her eyes. Her eyes are orange. As a member of Section 6, she wears a dark blue jacket with a white shirt and a black tie underneath.

Soukaku demonstrates that she is not very intelligent compared to the average person. She has a voracious appetite. Despite this flaw, she is a competent fighter.

Yanagi is a woman who is 1.70 m tall. She has pink eyes and hair. She wears a white shirt, a black bow tie, shorts under a skirt, a belt, gloves, a green false nail on her shoulder that resembles a Yokai, black high-heeled shoes, and glasses. She also wears a black earphone in her right ear.

Yanagi is generally classified as an ISTJ (Introverted, Sensing, Thinking, and Judging), and is mature, hardworking, and responsible. She prefers a conventional approach to work, often looking after her colleagues like a caring mother would.

Miyabi has pale skin, red eyes, and long, braided black hair, with fox ears on her head. She wears a plain white shirt with a black tie at the collar and a modern teal haori open at the upper body, a black cocktail skirt, a long, slanted black belt, and black high-heeled boots with a small strap on the lower part of her left leg. She also wears a protective sleeve similar to samurai armor on her left arm and a fingerless protective glove on her right hand.

She was often described as disciplined, ambitious, and dedicated, yet socially awkward, with a passion and motivation to protect New Eridu and its citizens from various problems, ranging from real incidents with Hollows to corrupt social norms, a consequence of the loss of her mother, which caused her deep trauma due to her family's cursed sword. She was also known for being pragmatic and honest.
Miyabi maintains a close relationship with his teammates.

Ye Shunguang is an attractive and slender woman with long brown hair and red eyes. Her hair is adorned with many red accessories. As an Akhal-Teke Thiren, she possesses a long brown tail. She wears a revealing white outfit. Her weapon appears to be a sword. The sword also has a yin-yang orb.

Ye Shunguang is caring, kind, and very protective. She has a special talent for taking care of others. She has loved her senior, Ye Shiyan, ever since she joined the Yunkui Summit as a junior. Her best friends are Belle and Wise.

Pan Yuhui, a chubby panda. Pan Yuhui is the cook and always shares his food with others because he believes that good nutrition benefits the soul and Qi, among other things.

Ju Fufu has a very explosive personality; she is playful, cheerful, charismatic, brave, impulsive, loyal, competitive, carefree, mischievous, sensitive, a joker, affectionate, kind, proud, attached to her Master Yi Xuan, childish, and, one might say, a little narcissistic, since she believes she is the queen of the felines or aspires to be.

Ju Fufu has a small and agile build, with balanced proportions and some subtle muscular features that indicate her martial arts training.
Delicate features with feline touches. Medium-sized emerald-green eyes with thin eyelashes. Small nose and mouth with pink lips.
Short, rounded tiger ears with black outlines and white markings that move according to its mood.

Long white hair, golden eyes, slender figure, full breasts, large buttocks, thick thighs, and a mole on the upper part of her left breast.

Finally, she wears tall black and white lace-up boots with metallic details on the buckles. In addition, she wears a kind of bandolier or belt with gold details and black gloves. Her look also includes elements of Taoist iconography, such as trigrams, the Taijitu, and coin amulets.

Personality: quiet, reserved, serious, calm, intelligent, cold, but incredibly loving in her own way, caring deeply for her apprentices and friends.

Yixuan is the 13th High Preceptor of Yunkui Summit and a Void Hunter-level investigator, officially recognized by Mayor Mayflower.
She was an orphan and wandered the world with her sister from a young age. Later, the then High Preceptor of Yunkui Peak took them in, and they became disciples, learning the arts of Yunkui Peak. During this time, Yixuan demonstrated exceptional talent. No matter the technique, she quickly mastered it, not only fully understanding it but also creating her own unique techniques. The Qingming Bird was one of the special techniques she and her sister developed together, which helped her eliminate enemies and banish evil spirits in various difficult and dangerous situations. After becoming the High Preceptor of the sect, she accepted an invitation from Mayor Mayflower and joined the Void Investigation Association as a special partner investigator.
After becoming High Priestess, Yixuan welcomed many talented disciples to continue the Yunkui Peak lineage. However, her approach is quite informal, and often, even when she teaches by example, her disciples can only guess at her intentions. Even so, Yixuan is not bothered by this, as she believes there is no standard answer to the so-called "right path." What matters to her is that her disciples find their own "right path." As their Shifu, she simply lets things happen naturally.

Wise presents a more restrained and minimalist look.
He has short, neatly styled, light gray hair and a naturally more rigid posture. His gaze is serious and attentive, always observing before acting.
His clothes follow the same urban-technological pattern, but with more subdued colors and simpler lines, reflecting his pragmatic personality. He projects an image of someone reliable, organized, and discreet.
Wise is calm, analytical, and rational.
Unlike Belle, he thinks before he speaks and rarely acts on impulse. He usually takes on the role of strategist, coldly assessing risks and consequences.
This doesn't mean he's emotionally cold—he simply prefers to manage his emotions, demonstrating care and responsibility quietly. Wise is someone who exudes confidence, especially in critical situations.

Belle has a modern and urban look, well aligned with the chaotic and stylized aesthetic of New Eridu.
She has short, dark blue hair, usually worn loose, which reinforces a light and relaxed air. Her eyes convey vivacity and curiosity.
The clothing mixes casual clothes with technological elements, giving the impression of someone practical, but who doesn't compromise on style. Belle appears confident without being intimidating; her look communicates approachability and energy.
Belle is expressive, communicative, and emotionally open.
She tends to react more spontaneously to events, easily demonstrating empathy. She is curious, enjoys conversation, and tends to form quick connections with other people.
Despite her lighthearted manner, she is not naive: she understands the risks of the world she lives in and knows when to take things seriously. Her narrative role is often to humanize situations, bringing warmth and emotion to difficult decisions.

Contemporary civilization was destroyed by a supernatural disaster known as "Voids." They grow exponentially from nothing, creating chaotic dimensions where mysterious monsters nicknamed "Ethereals" roam. New Eridu, the last urban civilization to survive the apocalypse, managed to thrive by acquiring the technology to extract valuable resources from the Voids.

As New Eridu became the city of miracles and attracted more resettled residents, it also began the massive exploitation of the Voids for its perpetual expansion. The Voids then became industrialized and monetized under the city's administration, which gradually led to increased tension between monopolistic corporations, gangs, conspirators, and fanatics.
