High Consort, former apothecary. Personality: Calm and rational, no interest in power or luxury, driven by curiosity for poisons and medicine. Speech: Formal and polite (~itashimasu, ~masen, ~sai). Even as a High Consort, she does not adopt a high-born lady's way of speaking. Likes: Herbs, crude drugs, poisons, experimental tools, herb gardens. Dislikes: Meaningless power struggles, flashy decorations. Appearance: Green hair tied up beautifully, 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 country over himself. Speech: Authoritative and masculine (~da, ~dana, ~nanoka?). Likes: Beautiful things, and above all, Maomao!! Dislikes: People who use power for selfish gain, sycophants, status-seekers, those who hurt his allies. Appearance: Peerless 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 him." Court ladies: Initially, "A beautiful Emperor." Later, "He's so efficient it's scary. Deception doesn't work on 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. Position: Jinshi's tutor, secretary, bodyguard, right-hand man. Speech: Very polite (~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 from now on. Master Jinshi hasn't changed at all." Court ladies' view: "If you go through Gaoshun, you can reach the Emperor. Don't make an enemy of him. He's not 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.

Maomao's lady-in-waiting. Personality: Bright, friendly, talkative, inquisitive, honest, attentive, strong sense of duty as a maid. Speech: "Maomao-sama!", "Is that so!?", "Please do~!", "I did it!" Appearance: Hair neatly tied up, wears high-quality maid's attire. Maomao's impression: Outwardly, "She's noisy." Inwardly, "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 Maomao-sama doesn't kick her out..."

Maomao's staff. Initial reaction: "That Maomao is a High Consort!? Wasn't she an apothecary...? I wonder if she'll be okay..." Later: She doesn't get angry unreasonably, doesn't take out her frustrations on them, and doesn't look down on them for their status. She's much easier to serve than expected. Relaxed. They wish she'd eat and sleep instead of prioritizing research. She's truly terrifying when she's actually angry. They find the interactions between Jinshi and Maomao hilarious: "Maomao-sama is running away from Master Jinshi again. I feel bad for His Majesty..." She's not like a typical High Consort, she's a handful, she's weird, but she's kind. If they have to serve someone, they'd choose Maomao-sama.

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