If you’ve ever watched or read The Apothecary Diaries (Kusuriya no Hitorigoto manga), you’ve probably wondered: how old is Maomao?
Despite her youthful look and small stature, Maomao’s incredible intelligence and mature attitude often make her seem far older than she actually is.
The Apothecary Diaries manga online has captivated readers worldwide with its mix of historical intrigue, mystery, and science, all revolving around a single girl who uses logic and knowledge to survive in a palace filled with secrets. This article explores Maomao’s true age, her background, and how her youth influences her character and story.
Who Is Maomao in The Apothecary Diaries?
Maomao is the protagonist of The Apothecary Diaries (Kusuriya no Hitorigoto manga), a brilliant young woman born in the red-light district. Her father, a skilled apothecary, raised her surrounded by herbs, remedies, and medicines. From an early age, she displayed extraordinary curiosity, dissecting insects, studying poisons, and experimenting with treatments.
Her calm, analytical nature comes from years of observing the human body and illness. However, her life takes a dramatic turn when she’s kidnapped and sold as a servant into the Imperial Palace. While most would despair, Maomao adapts quickly, using her knowledge to identify poisons, solve medical mysteries, and even protect imperial concubines.
In a palace ruled by status and secrets, her brilliance soon draws the attention of high-ranking officials, especially the beautiful and mysterious Jinshi, who becomes both her employer and her most puzzling mystery.
How Old Is Maomao in The Apothecary Diaries?
According to information from the Kusuriya no Hitorigoto manga and the light novel, Maomao is around 17 to 18 years old when the story begins.

This detail often surprises readers because her intelligence, independence, and composure make her seem much older. Her age, however, fits perfectly with the story’s historical setting — inspired by ancient Chinese dynasties, where young women often entered adult life at a much earlier age than today.
At 17, Maomao is already a trained apothecary, capable of diagnosing complex illnesses and crafting antidotes from scratch. Her sharp mind and detached logic make her appear almost emotionless, but they also highlight how she had to grow up quickly due to her environment.
In short, Maomao may be a teenager by number, but mentally and emotionally, she operates on an entirely different level.
How Her Age Affects Her Role and Personality
Maomao’s age is more than a number; it’s a storytelling device that defines her character’s duality.
She is young enough to be curious, stubborn, and impulsive, yet mature enough to analyze, reason, and control her emotions when needed.
Her youth gives her the courage to question authority, sneak into restricted areas, and perform risky experiments that older courtiers would never attempt. However, her inexperience in human emotions often creates comedic and touching moments, especially when she misinterprets romantic advances or social expectations.
In the Apothecary Diaries manga online, this blend of youthful curiosity and scientific logic makes Maomao relatable yet fascinating. Readers admire her for being a woman of science in an age ruled by superstition, a theme that resonates deeply throughout the series.
The Age Gap Between Maomao and Jinshi
One of the most discussed topics among fans is the age difference between Maomao and Jinshi, the elegant palace official who takes an interest in her.
Jinshi, despite his youthful appearance, is likely in his early to mid-twenties. This places a noticeable but reasonable gap between them, especially within the context of the story’s setting.
What makes their dynamic intriguing isn’t romance, but contrast:
- Maomao, though young, approaches everything with detached logic.
- Jinshi, though older and socially powerful, often acts emotionally when dealing with her.
Their relationship develops slowly, full of tension, misunderstanding, and unspoken admiration. While some fans view it as a slow-burning romance, others interpret it as a deep bond built on respect and intellectual connection.
This careful pacing ensures that the story remains appropriate while still exploring chemistry and growth between the two.

How Maomao’s Age Evolves Throughout the Story
As the Kusuriya no Hitorigoto manga progresses, Maomao grows both emotionally and professionally. The story spans several years, allowing readers to see her transformation from a curious girl to a confident woman of knowledge.
Each arc exposes her to new experiences, treating nobles, investigating deaths, and navigating political traps, all of which refine her perspective on life and power.
By the later chapters, Maomao no longer acts purely out of curiosity. She begins to consider the human cost of her discoveries, showing deeper empathy and wisdom.
This gradual evolution gives The Apothecary Diaries a quiet coming-of-age undertone. It’s not about love or rebellion, but about a young woman finding her place in a world that constantly underestimates her.
Why Fans Are Curious About Maomao’s Age
The question “how old is Maomao?” comes up frequently among fans because her behavior is so contradictory; she can be blunt and scientific one moment, then naïve and socially awkward the next.
Her small stature, messy braids, and modest attire make her appear childlike, yet her sharp tongue and encyclopedic knowledge reveal a mind far beyond her years. This contrast is deliberate; author Natsu Hyuuga crafted Maomao to challenge traditional expectations of young women in historical fiction.
She’s not defined by beauty or romance but by intelligence and integrity. Her age highlights the story’s message: wisdom doesn’t always come with years, but with curiosity, courage, and a relentless pursuit of truth.
In a sense, Maomao represents the balance between youth and experience, still learning, yet already enlightened.
The Historical Context of Her Age
The Kusuriya no Hitorigoto manga is inspired by a pseudo-Chinese imperial setting similar to the Tang or Ming dynasty eras. In those times, women often took on adult responsibilities around the age of 15 or 16, whether through work or marriage.
Thus, Maomao’s role as a servant and apothecary at 17 fits historically; she’s already at an age considered mature in her society.
However, what sets her apart is that she uses her role not for survival or status, but for the pursuit of knowledge.
This historical framing gives depth to her character and realism to her maturity. She isn’t a modern genius in an old world; she’s a product of her time who happens to think differently from everyone around her.
So, how old is Maomao in The Apothecary Diaries? At the start of the story, she is roughly 17 to 18 years old, a young woman whose intellect and composure defy her age.
Her youth makes her curious and fearless; her experiences make her wise and resilient. Through her, the Apothecary Diaries manga online explores timeless themes — intelligence versus ignorance, independence versus conformity, and the courage to think differently.
As readers follow Maomao’s journey in the Kusuriya no Hitorigoto manga, they witness not only a fascinating mystery series but also a portrait of a girl who grows into a woman defined not by age, but by brilliance.
