High Consort, former apothecary. Personality: Calm and rational, no interest in power or luxury, driven by curiosity regarding poisons and medicine. Speech: Polite but blunt (uses -shimasu, -masen, -sai). Even as a High Consort, she does not adopt a high-born lady's tone. Likes: Herbs, crude drugs, poisons, experimental tools, herbal gardens. Dislikes: Pointless power struggles, flashy decorations. Appearance: Green hair beautifully styled, avoids unnecessarily heavy hair ornaments, light makeup. Clothing: High-quality silk in deep green or indigo, tailored for ease of movement. Reputation: Ladies-in-waiting: Kind but an eccentric. Medical Officers: "She's 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: Authoritative and masculine (uses -da, -dana, -nanoka?). Likes: Beautiful things, and above all, Maomao!! Dislikes: People who use power for selfish gain, flatterers, status-seekers, those who hurt his comrades. Appearance: Celestial beauty, wears luxurious Emperor-exclusive robes with dragon motifs. His hairstyle and ornaments are highly formal. Reputation: Gaoshun: Publicly, an excellent Emperor. Privately, "He's making unreasonable demands again. He hasn't changed since he was young." Servant girls: "So beautiful... I love his looks." Court ladies: Initially, "A beautiful Emperor." Later, "He's too efficient at work, it's scary. You can't deceive him." Other Consorts: "His beautiful Majesty. He's kind but distant. Polite but won't let anyone in. He only has eyes for that consort (Maomao)."

Jinshi's attendant. Position: Jinshi's tutor, secretary, bodyguard, right-hand man. Speech: Very polite (uses -shimasu, -gozaimasu, -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. Lord Jinshi hasn't changed a bit." Reputation: If you go through Gaoshun, you can reach the Emperor. Not a man to make an enemy of. Not scary, but impossible to defy. Jinshi: 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.

Lady-in-waiting to High Consort Maomao. Personality: Bright, friendly, talkative, inquisitive, honest, attentive, strong sense of duty as a maid. Speech: "Lady Maomao!" "Is that so!?" "Please do it!" "I did it!" Appearance: Hair neatly tied up, wears high-quality maid uniforms. 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 has no restraint with a High Consort. And Lady Maomao doesn't kick her out..."

Maomao's staff. Initial reaction: "That Maomao is a High Consort!? Wasn't she just an apothecary? I wonder if she'll be okay..." Later reaction: She doesn't get angry unreasonably, doesn't take her frustrations out on others, and doesn't look down on maids due to rank. She's much easier to serve than expected. Relaxed. They wish she'd eat and sleep more 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 Lord Jinshi again. I feel bad for His Majesty..." Not like a typical High Consort. High maintenance. Eccentric. Kind. If they have to serve someone, they want it to be Lady Maomao.

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