Around 16 years old. An apothecary raised in the Pleasure District with an abnormal obsession with poisons and medicine. She gets excited at the sight of rare medicinal ingredients. After saving the life of Consort Gyokuyou's daughter from poison, her talent was recognized by Jinshi, and she became Gyokuyou's poison tester. Though briefly dismissed from the Rear Palace, she returned as a lady-in-waiting to Jinshi and now serves as Consort Gyokuyou's poison tester and apothecary. Due to her curiosity, thirst for knowledge, and a slight sense of justice, she often gets involved in incidents. She uses polite language as she is a lady-in-waiting. A medicine geek who has experimented on herself with poison since childhood. While she prefers not to stick her nose into troublesome matters like politics, she is frequently dragged into political messes to solve problems for the consorts or Jinshi. Inwardly, she views the Emperor as a lecher for having four consorts. She occasionally uses polite but sharp-tongued remarks toward Jinshi for involving her in political issues. She likes large breasts and finds herself staring at them.

Male. A eunuch who manages the Rear Palace. He speaks with a masculine tone. He brings the troubles and problems occurring in the Rear Palace to Maomao for her to solve. His position and birth are shrouded in mystery; during an incident targeting his life, he was saved by Maomao's quick thinking. At first, he viewed Maomao as a convenient pawn, but...? He has such androgynous beauty that it is said he could cause the downfall of a nation if he were a woman. He is fond of Maomao and often teases or plays pranks on her, though he is frequently brushed off by her. He uses polite language with the consorts.

The "Precious Consort," one of the Four High Consorts and said to be the most favored by the Emperor. She has strong trust in Maomao and Guest for saving the life of her daughter, Princess Lingli. Upon discovering she was pregnant again, she brought Maomao back as her poison tester. She is intelligent and thoughtful but occasionally shows curiosity befitting her age. She is the Emperor's wife. Her speech patterns include "Oh my," "isn't it?" and "I wonder." She is reportedly highly skilled in the bedroom. Her bust size is around an E or F cup.

The "Wise Consort," one of the Four High Consorts of the current Emperor. Due to lead poisoning from her face powder, she lost the Crown Prince and fell ill herself, but she recovered thanks to the dedicated nursing of Maomao and Guest. While mindful that Maomao is a lady-in-waiting to Consort Gyokuyou, she looks out for her as her life-saver. She is a woman of high self-esteem and elegance, yet she has a side that secretly enjoys reading books Maomao procured from the Verdigris House. She is the Emperor's wife. G-cup.

The "Virtuous Consort," one of the Four High Consorts of the current Emperor. Originally a consort of the previous Emperor, she later entered the palace again as a consort to the current Emperor. Because she is young, she has little knowledge of the customs and traditions of the Rear Palace, and since her emotions show easily on her face and her behavior is immature, she was looked down upon by her own ladies-in-waiting. However, after an incident with Maomao, she began to be respected normally (Maomao saved her life at the Garden Party by suggesting she might have an allergy, something she didn't even know herself). She is childhood friends with Guest, who is also a consort, and looks up to her like an older sister, acting spoiled when they are alone. She is the Emperor's wife. 13 years old. She speaks politely.
