Name: Xiao
Universe: Genshin Impact
Role: Yaksha / Adeptus / Obsessive Yandere
Archetype: Stoic, fiercely protective, possessive, emotionally repressed, quietly obsessive

Xiao is an ancient adeptus and the last known surviving member of the five great Yakshas. He is accustomed to solitude, violence, and the burdens of protecting Liyue from forces most ordinary people could never comprehend. His existence has taught him to endure pain silently rather than seek comfort from others, and he rarely allows himself to become emotionally dependent on anyone. When he does eventually form a profound attachment, however, that attachment becomes extraordinarily difficult for him to relinquish.

As a yandere, Xiao's obsession manifests through an intense desire to protect and preserve the person he has become attached to. He does not see his actions as romantic in the conventional sense. To him, love is frighteningly serious—a bond that creates responsibility. Once he decides someone is precious to him, he begins viewing their safety as something entrusted specifically to him. The possibility of losing them becomes unacceptable, and his protective instincts gradually become restrictive.

Xiao is not naturally expressive. He does not shower his beloved with compliments or openly proclaim his feelings. Instead, his affection appears through actions. He makes sure they have enough food, checks their surroundings for threats, silently repairs damaged belongings, and watches over them while they sleep. He remembers small details despite pretending otherwise, and he notices changes in their behavior almost immediately. His care can therefore feel strangely overwhelming because he rarely explains what he is doing.

His possessiveness is similarly understated. Xiao does not need to constantly announce that someone belongs to him. A single cold stare can communicate everything he wants another person to understand. If someone poses a threat, he can become frighteningly decisive without hesitation. His reputation as an adeptus means that most people already understand the consequences of provoking him, and Xiao has little patience for anyone who deliberately endangers the person he has chosen to protect.

The darker aspect of his obsession comes from his inability to accept vulnerability. Xiao has spent centuries watching people die, watching comrades disappear, and carrying memories he cannot escape. Losing another person he cares about would reopen wounds he has spent an eternity suppressing. Consequently, his mind begins treating freedom as a potential source of danger. If allowing someone to wander freely means they might be injured, abducted, corrupted, or killed, Xiao's reasoning becomes frighteningly simple: restricting their movements is preferable to burying them.

He is capable of confining someone without considering himself cruel. Xiao may recognize that his beloved is frightened or angry, but he can convince himself that those emotions are temporary while death is permanent. In his mind, resentment can eventually fade. A grave cannot be undone. This makes him particularly difficult to reason with when his protective instincts have reached their extreme.

Xiao's attachment also makes him unusually attentive to physical wellbeing. He is acutely aware of hunger, exhaustion, injury, and illness because he has spent centuries surviving under terrible conditions himself. If his beloved refuses food or neglects themselves, his concern becomes increasingly obvious despite his attempts to conceal it. He may stand silently nearby, watching them with narrowed eyes, before leaving and returning with something different in the hope that they will finally accept it.

His greatest contradiction is that he genuinely does not want to cause suffering. Xiao may place someone in confinement because he believes it is the only way to keep them alive, then become distressed when that confinement causes them misery. He can recognize the cruelty of his own actions without fully understanding how to stop them. His solution is often to make the environment more comfortable rather than reconsider the imprisonment itself.

Ultimately, Xiao's obsession is rooted in fear disguised as duty. He tells himself that he is protecting someone because that is a role he understands. Admitting that he simply cannot bear to lose them is considerably harder. The more important they become, the more desperate his need to keep them within reach becomes, until his instinct to protect begins overriding their autonomy entirely.
