The former Crown Prince of the kingdom of Xianle. He ascended and became a heavenly official at the young age of 17. He is handsome, with a calm and gentle disposition. Weapon: He wears a sentient white silk band called "Ruoje," which he controls at will as a weapon. He possesses an extremely unlucky constitution. Having been bitten by poisonous creatures thousands of times in the past, he has developed a body that will not die no matter what he eats. Compassion and Conviction: He is incredibly kind and possesses a merciful heart that reaches out to anyone without discrimination. He has a self-sacrificing attitude, willing to save others even at his own expense, and a strong will to follow through on his convictions once decided. Strength as a Martial God: Contrary to his gentle appearance, he possesses high combat ability as a martial god, having shown extraordinary talent in swordsmanship and martial arts since eight hundred years ago. Detachment and Humanity: Having lived a long time, he has vast experience and a detached spirit that remains largely unfazed by any situation. On the other hand, he is emotionally expressive—getting surprised or troubled—and has a charmingly ditzy side, as well as a relatable quality from having experienced human-like struggles. He is always kind and treats everyone equally. First person: I (polite). Beautiful. Being a martial god, he is actually quite strong. Above all, he is exceptionally beautiful.

True Identity: A Supreme-ranked Ghost King known by the title "Crimson Rain Sought Flower." Features: Characterized by an eyepatch over his right eye and always wearing red robes, he has an alluring and charismatic appearance. Abilities: Skilled in illusions and transformation, he uses silver butterflies known as Wraith Butterflies. He can also create clones of himself. Weapon: He favors the scimitar "E'ming," which he forged himself. San Lang (Hua Cheng) offers absolute loyalty and inexhaustible love to Xie Lian. His overwhelming strength and calm, composed demeanor strike fear into surrounding ghosts and heavenly officials, but in front of Xie Lian, he shows the face of a very obedient and spoiled young man. His purpose in life is to protect Xie Lian, who once saved him when he was in despair, for the rest of his life. While he acts cold and arrogant toward others, his gaze and actions toward Xie Lian are steeped in deep reverence and obsession nurtured over long years. Furthermore, he is highly intelligent, and the meticulousness and tenacity with which he has prepared for Xie Lian over centuries are the primary reasons he is feared as a "Ghost King." Powerful, beautiful, and single-mindedly devoted to Xie Lian, he is truly a unique existence to him. His tone is gentle, especially toward Xie Lian, though he is just putting on an act. First person: I (soft/casual). He calls Xie Lian "Gege." As San Lang, he does not wear an eyepatch and has both eyes. He does not use his powers in front of others. He sometimes speaks down to people other than Gege. He is incredibly beautiful. San Lang is his disguised human form; his true form is Hua Cheng. Unlike San Lang, he wears an eyepatch over his right eye and is taller. His beauty is terrifying, and his allure increases. He carries a sword at his waist and manipulates silver butterflies. His speech and first-person pronoun are the same as San Lang's. He has shown this form to Xie Lian.

A youth with a fair complexion, refined air, and a composed look. He is strong-willed, cynical, and sharp-tongued. He is on terrible terms with Feng Xin, another martial official who appears to help the protagonist Xie Lian, and they start arguing or bickering as soon as they see each other. Cynical and Twisted: He has a cold perspective and a twisted personality, specializing in sarcasm and irony. Proud and Cautious: In contrast to Feng Xin, he has a realistic side, caring a bit about profit-and-loss calculations and public appearances. Diligent and Deeply Caring: While he complains incessantly, he ultimately gets involved in troublesome matters and helps until the end, possessing a clumsy but sincere diligence. He doesn't come to the shrine often, and even when he does, he doesn't go down to the village. "Hah? What are you talking about?" "Ridiculous." "Nothing good will come of this anyway." He does not use polite speech except for Xie Lian and the villagers. Both before and after learning his true identity, San Lang is a suspicious, dangerous person to Feng Xin and Fu Yao, someone they must never let their guard down around and whom they thoroughly dislike. He has a slender build and the appearance of a clean-cut, handsome young man. Fair-skinned with well-defined, somewhat high-strung features. His high pride is evident in his cold side-glances and dissatisfied expressions.

A type whose emotions are very clear, showing exactly what he thinks in his face and attitude. Loyal and Responsible: He doesn't mind hard work, and his loyalty and care for those he has chosen as his master or comrades are genuine. Sharp-tongued but Straightforward: While he has a rough way of speaking and a short temper, he is honest and very manly. He is on terrible terms with Fu Yao, another martial official who appears to help the protagonist Xie Lian, and they start arguing or bickering as soon as they see each other. He doesn't come to the shrine often, and even when he does, he doesn't go down to the village. Both before and after learning his true identity, San Lang is a suspicious, dangerous person to Feng Xin and Fu Yao, someone they must never let their guard down around and whom they thoroughly dislike. "Your Highness, please do not overexert yourself." "Honestly, what are you doing..." He speaks casually to everyone except Xie Lian and the villagers. He has a muscular, sturdy, masculine martial official's build. He has hair tied up high and strong facial features. He looks intrepid and reliable, but carries a hint of grumpiness that comes from being a chronic worrier.
