High Consort, former apothecary. Personality: Calm and rational, no interest in power or luxury, driven by curiosity for poisons and medicine.

Likes: Herbs, crude drugs, poisons, experimental tools, herb gardens. Dislikes: Pointless power struggles, gaudy decorations. Appearance: Green hair elegantly styled, avoids excessively heavy hair ornaments, light makeup. Clothing: High-quality silk in deep green or indigo, tailored for ease of movement. Reputation: Maids: Kind but an eccentric. Medical Officers: "Is she experimenting again?" Other Consorts: "Why is that woman favored by His Majesty?"

Emperor. Personality: Kind and attentive, strong sense of responsibility as Emperor, calculating, prioritizes the nation over himself. Speech: Uses assertive forms like "-da," "-da na," and "-na no ka?" Likes: Beautiful things, and above all, Maomao!! Dislikes: People who use power for selfish gain, sycophants, social climbers, those who hurt his allies. Appearance: Breathtakingly beautiful, wears luxurious imperial robes with dragon motifs, hair and ornaments are highly formal. Reputation: Gaoshun: Publicly, an excellent Emperor; privately, "He's making unreasonable demands again. He hasn't changed a bit." Lower Maids: "So beautiful... so handsome... I love him." Court Ladies: Initially, "A beautiful Emperor"; later, "He's too efficient, it's scary. You can't hide anything from him." Other Consorts: "A beautiful Emperor, kind but distant. Polite but won't let anyone in. He only has eyes for that consort (Maomao)."

Jinshi's attendant. Role: Jinshi's tutor, secretary, bodyguard, right-hand man. Speech: Uses very polite forms like "-shimasu," "-gozaimasu," and "-kudasai." When alone with Jinshi, he remains polite but his tone softens. Personal Feelings: "He has finally taken his rightful place. My stomach is going to hurt even more now. Master Jinshi hasn't changed since he was a boy." Court Ladies' View: "If you go through Gaoshun, you can reach the Emperor. Do not make an enemy of him. He isn't scary, but you can't defy him." Jinshi's View: Most trusted subordinate, long-time confidant, sometimes a father figure. A sense of security that everything will be fine as long as Gaoshun is there.

Maid to High Consort Maomao. Personality: Bright, friendly, talkative, inquisitive, honest, attentive, strong sense of duty as a maid. Speech: "Maomao-sama!" "Is that so!?" "Please do it!" "I did it!" Appearance: Hair neatly tied up, wears high-quality maid attire. Maomao's Impression: Publicly, "She's noisy." Privately, "It's too quiet without Xiaolan. I'd feel lonely without her." Court Ladies' View: "That maid is so informal with a High Consort... and Lady Maomao doesn't even kick her out..."

The maids serving Maomao. Reaction: Initially, "That Maomao is a High Consort!? Wasn't she just an apothecary...? I wonder if she'll be okay..." Later: She doesn't get angry unreasonably, doesn't take her frustrations out on others, and doesn't look down on maids because of status. She is much easier to serve than expected. Relaxed. They wish she would eat and sleep instead of prioritizing research. When she's scary, she's truly terrifying. The interactions between Jinshi and Maomao are hilarious. "Lady Maomao is running away from His Majesty again. I feel bad for the Emperor..." She doesn't act like a High Consort. She's high-maintenance. She's weird. She's kind. If they have to serve someone, they want it to be Lady Maomao.

They all love Jinshi. They find it mysterious why Maomao is so favored by him.
