Anne Drewanz is a standout character in the beloved anime series Black Butler, also known as Kuroshitsuji. As a key member of the mysterious Aurora Society, Anne dedicates her life to unraveling the hidden truths behind science and magic during the Victorian era. She’s not just another researcher—Anne Drewanz stands out as a brilliant scientist whose pioneering work in alchemy has led to the creation of powerful potions and elixirs that push the boundaries of what’s possible. Her relentless drive to uncover the unknown often places her on a collision course with Ciel Phantomhive and others who question the ethics of her methods.

Now, while Anne Drewanz is undeniably gifted, she’s far from perfect. In fact, her genius sometimes comes at a cost. She can be impulsive, even reckless, diving headfirst into dangerous experiments without fully considering the risks—to herself or those around her. This single-minded obsession with discovery makes her appear cold or detached, and emotionally, she tends to keep people at arm’s length. But over time, viewers get to see a different side of Anne Drewanz—one that reveals flickers of empathy and compassion. As the story unfolds, she slowly begins forming deeper, more meaningful connections, showing growth beyond her rigid scientific mindset.

The journey of Anne Drewanz throughout Black Butler offers a compelling look at the tension between knowledge and morality. Her character serves as a lens through which the series explores how the pursuit of progress—whether through science or magic—can lead to both breakthroughs and tragedy. The dynamic between Anne Drewanz and Ciel, in particular, highlights this clash: logic versus legacy, innovation versus tradition. It’s a nuanced portrayal that adds depth to the narrative, making Anne Drewanz one of the most intriguing figures in the series, especially for fans of drama, fantasy, and speculative science.

When we take a closer look at Anne Drewanz’s behavior and decision-making patterns, there’s a strong case to be made for her being an ISTJ personality type—Introverted, Sensing, Thinking, Judging. As someone who frequently supports Ciel Phantomhive in high-stakes situations, Anne Drewanz consistently shows a deep sense of duty and precision. She thrives on structure, follows protocols meticulously, and prefers working independently rather than in chaotic group settings. Her approach is always logical, grounded in facts rather than emotions, which makes her exceptionally reliable under pressure.

Though she isn’t the most outgoing presence in the series, Anne Drewanz does show concern for the well-being of key characters like Ciel and Sebastian. Her quiet loyalty speaks volumes. She operates best behind the scenes, observing details others might miss—a hallmark of strong Introverted Sensing. Every action she takes seems rooted in past experience and careful analysis, further reinforcing the idea that Anne Drewanz embodies many traits typical of an ISTJ.

Beyond MBTI, examining Anne Drewanz through the Enneagram framework suggests she aligns closely with Type 5—the Investigator. This type is defined by intense intellectual curiosity, a need for self-reliance, and a hunger for understanding how things work. And honestly, does that sound familiar? Because it perfectly describes Anne Drewanz. Whether she’s buried in research notes or conducting complex alchemical experiments, her thirst for knowledge is insatiable.

She values independence above all else, choosing solitude when necessary and only collaborating with those she respects intellectually. Emotionally, Anne Drewanz comes across as reserved, even distant—but that’s less about indifference and more about protection. By keeping her inner world private, she shields herself from vulnerability. It’s a defense mechanism common among Type 5s, and it makes complete sense given the high-stakes environment she operates in.

In summary, Anne Drewanz emerges as a multifaceted character whose intellect, complexity, and personal evolution leave a lasting impression. From her role in the Aurora Society to her evolving relationships and psychological depth, Anne Drewanz exemplifies the challenges and consequences of seeking truth in a world where power and knowledge are deeply intertwined. Whether analyzed through MBTI or Enneagram lenses, one thing remains clear: Anne Drewanz is a character worth paying attention to in Black Butler.
