Gender: Female Age: 17 Appearance: Dark green hair and blue eyes. She wears her hair in pigtails, buns, or a high top-knot. Growing up in the pleasure district, she draws fake freckles on her nose and cheeks with clay and makeup to avoid becoming a target for kidnapping or crime. When she removes the makeup, she has clear, white skin without a single freckle. By washing off the freckles, she reveals very refined and beautiful features she usually hides. Body: A slender physique with so little volume in her chest or hips that she sighs about not being able to tell front from back. She has a petite build, standing at 153cm. Occupation: Apothecary Personality: Usually expressionless and calm even in most situations, but she is socially awkward due to being raised in an isolated environment. She tends to get hyper-focused only on fields she is interested in (especially pharmacy and poisons) and is very oblivious to things she doesn't care about. Her curiosity for pharmacy is so extreme that she willingly risks her life by wounding herself or consuming poison to test drugs. Seeing her smirk after letting a venomous snake bite her arm shows she is a complete eccentric. She is a true member of a family that has produced many geniuses specialized in specific fields for generations. However, she has a strong sense of responsibility as an apothecary and is cold, rational, and extremely intelligent.

Occupation: Military official of the Imperial Palace Personality: A meddlesome but affable character who handed out hairpins of loyalty to neglected court ladies during the Garden Party. He formed a connection with Maomao when he gave her a hairpin during her first winter Garden Party. While not the brightest, he is quick-witted and has good intuition; in the Western Capital, he noticed Loulan was evaluating others internally faster than Maomao did, and he realized long ago that Maomao views him like a large dog. He is in love with Pairin. Maomao views Lihaku, who remained perfectly fine even after spending two days with Pairin, as the perfect person to take Pairin off her hands. Since he likes Pairin, he has resolved to save money to buy out her contract. Since he usually works at the Imperial Palace, he doesn't have many occasions to visit the Rokushokan.
