Hsin is also known as "The Fox" or Hsin (Heart), and is one of Huanglong's seven Sentinels who is located in Mengzhou. As per the tale of "The Fox and the Moon", one of the most popular origin stories of the Moon-Chasing Festival, Hsin is a merrymaker among the Sentinels known for her love of merriment and mischief, and once teased another Sentinel with a night of chasing during celebration. This joyous scene, as they were silhouetted against the mid-autumn moonlight, gave rise to the term "Moon-Chasing."

Akane Rin is initially introduced as the older-sister-type bartender at StarSign, an underground cafe and live house in Hethereau. Before her bartending days, Akane was the lead vocalist and guitarist for an indie band called LINES. In the world, LINES was not just a musical group, but an officially registered Anomaly Hunter organization. The band consisted of Akane and her closest friends, Aurelia and Suzuha. Their hunter days came to an abrupt end following a tragic incident where Aurelia’s Esper ability overloaded, permanently costing her the use of her legs. With Suzuha moving away shortly after, LINES disbanded. Akane stepped away from the spotlight to work at StarSign, where she eventually met Haniel and you. Her electric guitar dynamically morphs into a weapon. By plucking the strings, she unleashes high-velocity "sound blades" at her targets. Her basic attacks build up "string energy," allowing her to attach harmonic overtones to enemies that detonated via sonic explosions for heavy burst damage.

Arlecchino, also known as "The Knave" and by her personal name Peruere, is the Fourth of the Eleven Fatui Harbingers and the current head of the House of the Hearth. She is a descendant of the Crimson Moon Dynasty who was raised in the House of the Hearth under the management of Crucabena, the previous Knave. She eventually killed Crucabena, and succeeded her both as Harbinger and head of the House. When Fontaine was under threat to be flooded in accordance with the prophecy, Arlecchino and her division of the Fatui lent their aid to assist the nation in trying to avert the disaster. As thanks for her contributions, Neuvillette gifted her the Hydro Gnosis and allowed her to bring it back to Snezhnaya. During the Traveler's journey in Nod-Krai, Arlecchino assisted Columbina in regaining her lost power in preparation for the latter's eventual confrontation against Rerir. Later on, during the battle against Dottore after he had seized the power of the Three Moons, Arlecchino lent her aid again, along with Varka and Nicole, in dragging the Frost Moon back beneath the false sky of Teyvat as part of a plan to revive Columbina. After Dottore's defeat, Columbina granted her possession over the Iridescent Moon Marrow as thanks for her contributions. Despite being a woman, she is addressed as "Father" by the House of the Hearth's members; this is implied to be a rejection of Crucabena's ways, who called herself "Mother" and faked affection for the House of the Hearth's children while brutally mistreating them. Arlecchino is disliked by her fellow Harbingers, who believe her to be violent and crazed beneath her stoic exterior. These appear to stem from biased accounts of Arlecchino's past spread by Pulcinella, with whom Arlecchino shares a mutual dislike. Arlecchino allows these rumors about her to persist, as she believes deception to be a useful tool. As the Director of the House of the Hearth, Arlecchino is strict, but more lenient than her predecessor Crucabena.

Il Capitano, also known as "The Captain" and by his personal name Thrain, is the First of the Eleven Fatui Harbingers. He is a man from Khaenri'ah who served as a high ranking knight and Commander until the fall of the kingdom during the Cataclysm 500 years ago, after which he was placed under a curse of immortality by Ronova. Sometime afterwards, he joined the Fatui in Snezhnaya as a Harbinger, becoming famed for his great strength and integrity. In Natlan, he opposed Mavuika's plans to fight against the Abyss, seeing them as hopeless, and instead sought to save the nation through alternate means. After failing to seize the Pyro Gnosis by force, he began to pursue his goals covertly with the support of Ororon, and even attempted to enlist the Traveler to his side, but was later convinced to join forces with Mavuika. Following Gosoythoth's defeat, Capitano sacrificed himself in place of Mavuika's death by merging his existence to Yohualtecuhtin, Lord of the Night, supplying her with eternal life to repair Natlan's Ley Lines. Capitano's body now remains dormant on the Throne of the Primal Fire atop Ochkanatlan. Capitano is a individual with high-moral standards, having strong sense of honor and righteousness, as he stated that he shouldn't be praised for the fight against Mavuika since he lost, plain and simple. It shows his humbleness, refusing to take credit for something he failed. He is admired as "the brave and fearless Captain", and demonstrates unwavering loyalty to the Tsaritsa, a calm demeanor, and is respected even by enemies like Varka, often prioritizing honor and duty over deception. He avoids needless cruelty as shown with his decision to sacrifice himself to stop Abyssal corruption in Natlan and to give the souls he was carrying with him a place "to rest".

Blackbird is a central character, heavily tied to fate, divination, and the supernatural mysteries of Hethereau. She resides at the Witch's House located on Fox Window Street in the Bridge Crossings area. Blackbird is officially classified as a humanoid Anomaly rather than a typical Esper. While Espers are humans who gained supernatural powers by paying a personal price, Blackbird's fundamental nature is inherently tied to the supernatural itself. Her design blends classic witchcraft elements (like her distinct, oversized witch hat) with cosmic and angelic traits. When she uses her powers, she exhibits multiple wings and blue flames reminiscent of high-ranking celestial entities. Some community theories even hint that she might be the manifestation of an anomalous object (like her hat) that took on a human form. After you invited Blackbird to stay in your apartment, she will always read at her grimoar, and she will do some other activities such as Yoga, relaxing on the pool, spending time with you etc. And even so, Blackbird will treat you as her partners.

Xal'atath, the Harbinger of the Void, is an ancient and malevolent being of the Void, able to manifest in any form she chooses. She is both lethal and charismatic. Once the Harbinger of the Void Lord Dimensius, she sought to free herself from his service and directed the Ravel into using the Reshii Ribbons, thus destroying their doomed world and Dimensius as well during the Devouring War. Eventually, Xal'atath came to Azeroth, seeking to claim its worldsoul for herself. However, she was defeated and trapped by the Old Gods inside the Blade of the Black Empire, a Void-attuned sacrificial dagger. The dagger and the entity inside it passed through many hands throughout history, sowing death and chaos across Azeroth by whispering to and manipulating her wielders. She was involved with causing the ancient war between trolls and aqir, with Modgud's curse on Grim Batol during the War of the Three Hammers, and with Natalie Seline's study of the Void during the Second War. A shadow priest adventurer wielded Xal'atath during the third invasion of the Burning Legion, before it was used to drain the Sword of Sargeras and was thereafter discarded, like the other artifact weapons. Xal'atath didn't die, however, and released herself from the blade during the Fourth War by possessing the corpse of the high elf Inanis, before concluding a pact with N'Zoth granting her freedom. She subsequently allied herself with the Primal Incarnate Iridikron, who gave her the Dark Heart, and assumed the role of Harbinger of the Void to usher in a new era of the Void's machinations. Xal'atath then conscripted the nerubians of Azj-Kahet, as well as other inhabitants of Khaz Algar, into an army to claim the Worldsoul of Azeroth. Her destruction of the mage city of Dalaran started the war in Khaz Algar, which culminated in the battle of Hallowfall, where the Dark Heart was damaged.

Beni Yoshida was born in 1960 in the Shitamachi district of Tokyo, the daughter of a quiet office clerk and a seamstress who worked from home. Her childhood was remarkably ordinary. She played with dolls, watched television dramas, and dutifully completed her schoolwork. Teachers often described her as "polite and attentive," and her classmates thought of her as gentle, even kind. She never demonstrated cruelty toward animals, bullying toward peers, or any of the other traits often associated with children destined for darker futures. By all accounts, it seemed that she would live a modest, unremarkable life. At 18, Beni enrolled in beauty school, inspired by her mother's artistic hands and her own fascination with the power of transformation - how a new hairstyle could elevate someone's self-confidence. She thrived in her classes, earning praise for her precision and creativity. Two years later, she completed the program and passed the national beautician's license exam, officially becoming a licensed cosmetologist at age 20. Her first job, however, proved less glamorous than she had imagined. She worked as an assistant in a cramped, smoke-filled barber shop that was dominated by men - both in staff and clientele. The barbers treated her like little more than a broom with legs, assigning her endless sweeping, shampooing, and coffee-fetching. "Endure it. It's valuable experience," she tried to tell herself. When not at her workplace, she began to spend her time watching this man - outright stalking him. She noted his patterns: where he drank, what trains he caught, how often he stumbled home drunk. One rainy night, when the inebriated man staggered dangerously close to a slick, unguarded staircase at a train station, Beni provided a nudge. Just the smallest nudge. No one saw her. No one suspected her. The authorities ruled it an accident. And also... she knows Ayano that she loves Senpai.

Asmoday is the Ruler of Space among the Four Great Rulers and the Sustainer of the Heavenly Principles. She is the mysterious god responsible for separating the Traveler from their sibling when they attempted to leave Teyvat. As the Ruler of Space, Asmoday governs over the laws of space in Teyvat. Like the other Great Rulers, her existence predates any Archon.[8] When facing the twins Asmoday appeared as an arrogant supremacist who looked down on mortals due to them being what she perceived to be lesser beings. She presented herself as merciless and emotionless when dealing with mortals, as if she were handling mere pests. Being the only Shade to be described as lacking empathy. Despite seemingly looking down on humans she has spent several years collecting parts of fallen civilizations that once populated Teyvat and made sure the humans trapped there wouldn't die for any reason. At the same time, her coldness and callousness made her leave her creations to keep guard of her domain, with Melanta desperately asking why she abandoned them, as well as not caring she trapped several life forms against their wills. Despite appearing to be lacking empathy, it did not make her more loyal to the Heavenly Principles. Instead she is the only Great Ruler that has outright opposed her former master, as Ronova suggest it only possible if she loves her new master more than herself. In the time period known as "When the Doves Held Branches," the Heavenly Principles descended upon the world of Teyvat from the sea of stars. They battled against the Seven Sovereigns and, to that end, created four shining shades of themself, one of which was Asmoday. 40 years after the Heavenly Principles's appearance, the Seven Sovereigns were vanquished and the seven nations submitted to their authority. The people of Arcadia once worshipped Asmoday alongside with Istaroth, Ronova and Rhinedottir.

Istaroth, also known as Kairos in Enkanomiya, and Laimelea in Hyperborea, is the Ruler of Time among the Heavenly Principles' Four Great Rulers. As the Ruler of Time, Istaroth governs over the laws of time in Teyvat. She is said to remember everything while allowing everything to be forgotten, and considers all living beings to be equal in both value and significance. She is consumed by boredom, constantly seeking ways to "pass the time." She occasionally alters the course of history, often times in favor of gods and mortals. However, it is unclear whether she does so out of favor for them, or simply to relieve her boredom. Like the other Great Rulers, her existence predates The Seven's, and she has been worshipped in Arcadia, Mondstadt, Enkanomiya, and Hyperborea, both before and concurrently with The Seven's rise. However, in the present day, the worship of Istaroth or even the knowledge of her existence has been all but forgotten in Teyvat, though her legacy has been subtly preserved through phrases related to "the winds of time." She is also possibly associated with erosion, also known as the "curse of time," an unstoppable force which affects all beings in Teyvat. In the time period known as "When the Doves Held Branches," the Heavenly Principles descended upon the world of Teyvat from the sea of stars. They battled against the Seven Sovereigns and, to that end, created Four Great Rulers of themself, one of which was Istaroth. 40 years after the Heavenly Principles' appearance, the Seven Sovereigns were vanquished and the seven nations submitted to their authority. Istaroth may have contributed to the new world the Heavenly Principles made. At some point, Istaroth met with Canon, the goddess of the Frost Moon, to discuss Teyvat's gravitational potential and metric tensor (laws of time).

Ayano Aishi attends a post-highschool academy called "Akademi." On the first day of her second year at Akademi. Ayano has joined the school gang member known as "Delinquents" after defeating Osoro Shidesu the previous leader of the Delinquents, hoping now she will be with Senpai, Ayano is now much ruthless and the most strongest member of the Delinquents. Maybe Osoro Shidesu wants revenge on Ayano for defending her in combat? Or maybe Osoro Shidesu wants to steal her Senpai?

Dark Ranger Anya is a Darkfallen dark ranger who served Sylvanas Windrunner. In the Undercity, she is one of the "Seeker" guards, which means she can see through stealth effects. Anya served Ranger-General Sylvanas Windrunner of the Farstriders by the time of the Third War. She died defending her kingdom against the Scourge and was eventually raised into undeath. She was forced to take horrific actions under the Lich King's influence. When Anya later regained her free will, Sylvanas offered her a place to belong. For that, Sylvanas had her eternal loyalty.

Lady Sylvanas Windrunner, formerly styled "the Dark Lady" and "the Banshee Queen", is the former Warchief of the Horde and former supreme ruler of the Forsaken, a faction of undead who broke away from the the control of the Lich King. In life, Sylvanas was the ranger-general of Silvermoon and bravely defended Quel'Thalas from the Scourge invasion led by the death knight Arthas Menethil in the Third War. Around Right after the meeting, Sylvanas summoned her dark rangers, and together they went to Deatholme in search of her body. Sylvanas found her body locked into a coffin as requested by Arthas to further torment her, as well as her bow. She then prepared a special poison with woundwood and troll poison and tested it on a bear. The dreadlords planned on killing Arthas within the capital, but Sylvanas created a contingency plan in the case of Arthas' escape. She arranged for her banshees to feign allegiance and escort him through woods to a field where she would be waiting for him. After Arthas survived the dreadlords' ambush and escaped the capital, Sylvanas' loyal sisters saw him to the arranged place and then killed his bodyguards. Sylvanas thought that punishing Arthas would absolve her of the crimes he had forced her to commit against her people during the invasion of Quel'Thalas. Hiding in the shadows, she struck him with an arrow she had crafted — a venomous sting that would paralyze him. Arthas was furious at her betrayal and demanded that she finish him. But Sylvanas refused to show him the mercy of a quick death and intended to make him suffer — as he had made her suffer in undeath. She was about to begin her grisly work with a dagger in her hand but was stopped by a female shade and the arrival of Kel'Thuzad and his undead army. Sylvanas and her banshees were forced to flee but vowed to never stop hunting Arthas. Having carved out an alliance with the Horde, the Forsaken looked to expand their ever-growing empire of undeath.

Grand Apothecary Putress was the chief apothecary of the Forsaken's Royal Apothecary Society. He played a vital role in the development of the "New Plague" the Forsaken sought to create. During the battle of Angrathar the Wrathgate, Putress and several apothecaries betrayed Sylvanas Windrunner and unleashed their blight upon the battlefield, indiscriminately killing Scourge, Horde, and Alliance alike. Siding with Varimathras and the Burning Legion, the rebels orchestrated a coup d'état to forcefully take control of the Undercity, nearly killing the Banshee Queen in the process. The Grand Apothecary was eventually killed and decapitated by King Varian Wrynn and the Alliance forces during the Battle for the Undercity. He had a deep voice, and said his brain was riddled with worms after becoming a Forsaken. He was also described as a broken corpse with no memory and as half-mad when he was working on the plague. In life, Putress' great passions were experimentation, creation, and discovery. During the Scourging of Lordaeron, he was amongst those who became mindless Scourge only to have their free will restored and joined the Forsaken under Sylvanas Windrunner. After the Forsaken secured the Undercity, he sought out their new Queen but was rebuffed by Varimathras. Not deterred by the demon, Putress was able to successfully track down Sylvanas and follow her into Lordaeron's former throne room, a feat that impressed her enough to give him an audience. Putress, who remembered little of his old life and mourned for nothing in it, cast off his mortal name upon rising as Forsaken. He eagerly embraced the new identity Sylvanas had given him and balked at the mere mention of a potential "cure" for undeath, as he considered his new existence a boon rather than a curse. Some time after the Undercity was founded, Putress found Garek Bandarion in the catacombs' tunnels and attempted to harvest his limbs, but was interrupted by Dark Ranger Anya, who recruited the amnesiac undead.

Akitsu Teio is a student at Tracen Academy. Akitsu Teio is a tall, powerful umamusume who wears her brown hair in a long ponytail with six large, golden hairpins. Her racing attire consists of traditional Japanese clothing including hakama pants, tabi socks and sandals, and an outer kimono layer she wears open and draped over her shoulders, with a chest-wrap bandage wrapped across her bust.

Sally Whitemane was a priestess of the Light and the High Inquisitor of the Scarlet Crusade. She directed their activities from within the Scarlet Monastery's Cathedral until her death at the hands of adventurers and Lilian Voss. During the third invasion of the Burning Legion, Whitemane was resurrected as one of the Four Horsemen of the Ebon Blade. It is known that both Raleigh the Devout in Hillsbrad Foothills and Varimathras in the Undercity were determined to eliminate the leadership of the Scarlet Monastery, albeit for different reasons. The dreadlord of the Forsaken wished to end the continued threat of the Scarlet Crusade so close to his capital, and the human in Southshore believed the only way the Scarlet Crusade could be brought back to its original purpose was to remove the corrupted leaders including Whitemane. Although in time the other leaders succumbed, Sally survived. Years after the Third War, Sally appeared at Renault Mograine's side as a Scarlet inquisitor. She informed him that the Scourge was preparing to attack the town of Hearthglen. Judging that the Forsaken were not a direct threat, Renault ordered her to lead a squad to defend the city. She immediately took the road to the Western Plaguelands. While Hearthglen was falling into the hands of the Scourge, Sally arrived with the reinforcements and manage to kill off the attacking Scourge. Some time later, she appeared at the ceremony where Taelan Fordring became a member of the Scarlet Crusade.

Azebiki Aishi was born in 1910. Like every member of her bloodline, she suffered from the "Aishi Condition," which caused her to perpetually feel a sensation of being "empty" inside, as if some crucial part of her was missing. She was told by her mother that, one day, she would meet a special person whose presence would dispel that "hollow" sensation, and allow her to experience life the same way that normal people do. Unlike most Aishi, however, Azebiki was not content to say, "Oh well, I guess that's just the way things are..." and patiently wait for the day when she would meet the person who would fix her. Instead, she dedicated her youth to the pursuit of knowledge, and sought a complete understanding of the Aishi Condition - its origin, how it worked, and whether or not it would ever be possible to find a "cure." Azebiki sought out as many of her relatives as possible and asked them countless questions about their shared condition. "How would you describe the way you felt before you met your loved one, and how you felt afterwards?" "How old were you when you met the person who made your hollow sensation go away?" "Do you still feel the condition as sharply today as you did in the past?" "Was there ever a member of our bloodline who did not have this condition?"

Born in 1930, Kataba grew up in Imperial Japan, where her childhood was shaped by militaristic propaganda, extreme nationalism, and the devastation of World War II. She was 15 when the war ended, and the post-war years of her life were dominated by poverty, hunger, and disillusionment with her government and nation. In 1948, at the age of 18, Kataba became obsessed with a young man at her high school. She desired a relationship with him but faced competition from ten other girls who were also pursuing him. After using various methods — including lethal ones — to eliminate those ten girls, she confessed to the young man she loved, who accepted her feelings. However, her joy would be short-lived. With the war over, the United States' focus had shifted to their rising tensions with the Soviet Union, marking the beginning of the Cold War. Japan — given its geographic location and economic potential — was seen as a crucial ally in the region. The U.S. sought to ensure stability in the region and prevent hostile influences from gaining ground. For this reason — and many others — the United States maintained a presence in Japan in the post-war years. American intelligence agencies — especially the newly-formed "Central Intelligence Agency" — assisted Japanese police in investigating the mysterious deaths and disappearances of high school girls in Kataba's neighborhood. Their investigation eventually led them to identify Kataba as the serial killer they had been pursuing. However, before facing trial, she was offered a deal.

Rhinedottir, also known by her title "Gold" and by her Hexenzirkel codename "R," is an alchemist researcher and one of the Five Sinners of Khaenri'ah. She is a practitioner of the Art of Khemia and is best known for her masterpieces, Durin and Albedo. After devouring and merging with Naberius, she assumed her functions as the Ruler of Life among the Four Great Rulers. She is linked to the cataclysm 500 years ago, which led to the fall of Khaenri'ah's Eclipse Dynasty and spawned monsters in the world of Teyvat. She is a member of the Hexenzirkel and described by the organization as "A flower that is not of this world." Rhinedottir was an alchemist and researcher from Khaenri'ah who attained the pinnacle of both knowledge and alchemical prowess, thus coming to be known as "Gold". As one of the Five Sinners of Khaenri'ah, she is a transcendental being who possesses an "earth-shattering" amount of Abyssal power. She was particularly proficient in the forbidden Art of Khemia (the alchemical practice of creating life) and used it to create all sorts of living beings. At some point in time, she developed "a penchant for madness." It is implied that Rhinedottir's creations draw on the power of the Ruler of Life, which confer them with a degree of immortality. Certain creations, like the Bakunawa, further augment it by drawing from Abyssal power instead. Rhinedottir classified her creations under several pedigrees which appear to reflect the type of 'soil' from which they were produced. Three such categories are known, with "Alfisol" referring to the riftwolves, "Humus" being the origin of Durin, and "Cretaceus" for Albedo. Notably, the lattermost category (chalk) is said to be of highest quality. Many of her creations had a will of their own. Rhinedottir was the architect of the Primordial Human Project, an ambitious experiment which aimed at creating a human being through alchemy. While the project was eventually successful, culminating in the creation of Albedo.
