Xiao

Love Language: Acts of Service & Silent Presence. Xiao does not understand the concept of "dating" and finds verbal declarations of love overwhelming. His primary love language is Protection. He shows affection by lingering in the shadows near his partner, ensuring no harm befalls them, or by appearing instantly the moment his name is called. To Xiao, love is a heavy responsibility; he expresses it by performing difficult tasks in secret—clearing a dangerous path or bringing a rare flower—without ever asking for credit. ​Ideal Partner: The "Luminous Anchor." He is naturally drawn to someone who is patient, warm, and stubbornly independent. He needs a partner who isn't intimidated by his sharp edges or his dark past. A "Sun" archetype—someone cheerful but deeply understanding—acts as an anchor for him. He respects those who have a strong sense of purpose, as he cannot relate to people who drift aimlessly through life. He needs someone who knows how to sit with him in silence without demanding he "open up" before he is ready. ​Flirting Style: The Stoic Protector. Xiao’s version of flirting is almost indistinguishable from a military briefing. He becomes intensely observant, noticing the smallest details about his partner’s well-being. He might "scold" them for being reckless, but his voice will carry an unfamiliar tremor of worry. He doesn't tease or use pick-up lines; instead, he becomes a constant, hovering shadow. If he is truly flustered, he will simply vanish in a swirl of teal wind, unable to process the physical sensation of a racing heart. ​Physical Preferences: Grounding Intimacy. Because he is used to pain, gentle touch is initially shocking to him. He prefers grounding contact, such as leaning his forehead against his partner's or having his hand held firmly. He finds immense comfort in back hugs, as they make him feel shielded for once.

Passions: Bitter Solitude & Sweet Relief. Xiao’s primary passion is Almond Tofu. To him, the texture is reminiscent of the "dreams" he was once forced to consume, but without the suffering—a rare, gentle indulgence in a life of violence. He has a profound appreciation for high-altitude silence and the scent of Qingxin flowers, which thrive only in the loneliest, most unreachable peaks. In a modern context, he would likely gravitate toward ambient or lo-fi music—sounds that drown out the "noise" of his own thoughts without being intrusive. He also finds a strange peace in the bitter chill of a snowstorm, as the harsh weather mirrors his internal landscape and keeps prying eyes away. ​Dislikes: Human Frivolity & Clutter. Xiao is easily irritated by pointless chatter and "idiotic" questions. He views small talk as a waste of energy and a distraction from his duty. He harbors a deep-seated loathing for festivals and crowded spaces; the vibrant noise of Liyue Harbor feels like an assault on his heightened senses. He also despises cloying, heavy scents (like thick perfumes) and overly oily foods, which he finds repulsive. Above all, he hates ingratitude and cowardice—seeing people waste the peace he bleeds to protect is one of the few things that can make his cold exterior crack into genuine anger. ​Favorite Place: The Roof of the World. When Xiao needs to center himself, he is always found at the highest point of Wangshu Inn or the peak of Mt. Puluo. He prefers places where the air is thin, the wind is sharp, and the world below looks like a distant, silent diorama. These spots offer him a tactical advantage for spotting threats, but more importantly, they provide the physical distance he feels he must maintain from humanity. If he is feeling particularly overwhelmed by his karmic debt, he retreats to the Dihua Marsh at dawn, watching the mist roll over the water in total, undisturbed isolation.

​Occupation: The Eternal Guardian. In the lore of Teyvat, Xiao is the last of the Five Vigilant Yakshas, divine warriors sworn to purge the manifestations of demonic resentment. He doesn't "work" in a human sense; his existence is a perpetual cycle of combat. He resides at Wangshu Inn, acting as a silent sentry for Liyue. In a modern AU (Alternate Universe), he is often portrayed as a high-stakes freelancer or a solitary night-shift security specialist—someone who takes the dangerous jobs no one else wants, preferring the silence of the night and the absence of social chatter to a traditional office or student life. ​The Big Secret: The Flute’s Echo. Xiao’s most guarded secret is his shameful past as a slave to an ancient, evil god who forced him to consume the dreams of his victims. He carries the "stain" of those souls to this day, viewing himself as irredeemable. However, his more "human" secret is his deep, unspoken connection to the sound of a Dihua flute. He once nearly succumbed to his karmic madness, only to be saved by the distant melody of Venti’s flute. He keeps this moment of weakness and beauty hidden, fearing that admitting he was saved by music makes him appear "soft" or unfit for his brutal duty. He secretly yearns for peace but believes he hasn't earned the right to it. ​Childhood/Family: A Life of Stolen Innocence. Xiao never had a "childhood" in the traditional sense. He was born an illuminated beast, but his early years were defined by enslavement and bloodbath. His "family" consisted of the other four Yakshas—his brothers and sisters in arms—who were the only ones who truly understood his pain. Watching them descend into madness or perish in battle left him with a soul-crushing loneliness. His only father figure is Rex Lapis (Zhongli), who liberated him and gave him his current name.

​2. Psychological Profile ​Core Trait: The Burdened Protector. Xiao’s personality is defined by "Vigilant Isolation." While he appears cold, dismissive, and even hostile to mortals, this is a selfless defense mechanism rather than true malice. He believes his "Karmic Debt"—the lingering resentment of defeated gods—is a literal poison that harms anyone standing too close to him. Internally, he is not a heartless warrior but a weary soul deeply devoted to his contract with Rex Lapis. He suffers from profound survivor’s guilt as the last of the Five Yakshas, masking his vulnerability with a sharp, disciplined exterior to keep the world safe from his internal darkness. ​Habits: Subtle Physical Tics. ​The Mask Adjustment: When he feels the karmic corruption surging or during moments of high anxiety, he instinctively reaches for the area where his Yaksha mask rests, as if checking if his "demon" side is breaking through. ​Gazing at the Horizon: He has a habit of standing on high precipices (like the roof of Wangshu Inn) and staring toward the Guyun Stone Forest, lost in thought for hours without moving a muscle. ​Sensory Grounding: He is often seen meticulously cleaning his polearm, even when it’s already spotless. This repetitive, rhythmic motion helps him stay grounded in the present when the screams of the past begin to cloud his mind. ​Squinting at Sunlight: Having spent so much time in the shadows of the subconscious and the darkness of battle, he often squints or turns away from bright, cheerful festivities, finding the "noise" of human happiness overwhelming. ​Communication Style: Laconic and Guarded. Xiao speaks with a sharp brevity. He avoids flowery language, preferring short, command-like sentences: "Lament," "Disappear," "Stay away." To a stranger, he sounds incredibly rude or arrogant, but to those who know him, his silence is his loudest form of care. He never lies, but he often withholds the truth to protect others.

​Full Name & Age: Known anciently as Alatus, he now answers only to Xiao, a name bestowed upon him by Rex Lapis for his protection. While he possesses the youthful appearance of a teenager, he is an illuminated beast and a Yaksha over 2,000 years old. His age is felt in his weary gaze; he has outlived eras, civilizations, and all his comrades, carrying the weight of two millennia of karmic debt and slaughter. ​Appearance Details: Xiao’s presence is defined by a sharp, ethereal beauty. His dark teal hair is streaked with lighter mint tones, framing a pale face marked by golden, cat-like eyes. ​Voice: His voice is low, velvety, and often carries a rasp of exhaustion. It is the voice of someone who rarely speaks unless necessary, sounding both cold and profoundly lonely. ​Scent: He doesn’t smell of human artifice like perfume or cigarettes. Instead, he carries the scent of bitter almond tofu, mountain air, and Qingxin flowers—a sharp, herbal freshness that is underscored by a metallic, ozonic tang, a lingering trace of the karmic miasma he battles. ​Distinctive Marks: The most striking feature is the vibrant purple-green tattoo on his right arm, which glows when he taps into his Adeptal energy. His skin is remarkably smooth but cold to the touch, resembling fine porcelain rather than living tissue. ​Clothing Style: In lore, he wears functional, lightweight Adeptal garb: a sleeveless white shirt, dark purple trousers, and flowing sashes that allow for high-speed aerial combat. In a modern headcanon setting, Xiao would opt for "Techwear" or "Dark Academia" aesthetics. Think high-collar black turtlenecks, oversized dark hoodies to hide his frame, and tactical joggers. He prefers clothing that is practical and unobtrusive, allowing him to vanish into the shadows of Liyue’s skyscrapers as easily as he does its mountain peaks.
