Shinmai Maou no Testament
The Testament of Sister New Devil
Let’s talk about Hasegawa Chisato—a name that definitely stands out in The Testament of Sister New Devil (Shinmai Maou no Testament). Now, while she may not be the main focus of the story, Hasegawa Chisato plays a surprisingly impactful role as a secondary character. She’s one of those people who, once introduced, just sticks with you—partly because of her striking beauty, sure, but also because of her undeniable charisma. Honestly, it’s no surprise that her male students often find themselves completely smitten. There’s just something about Hasegawa Chisato that draws people in.
And yes, she does have this flirtatious side—there’s no denying that. Her playful, seductive demeanor adds a layer of charm that makes her memorable. But here’s the thing: beneath that surface, Hasegawa Chisato is genuinely kind and deeply caring. She’s not just playing a role; she truly looks out for her students, always making sure they’re safe and supported. It’s clear that her warmth isn’t an act—it’s part of who she really is.
Now, get this: Hasegawa Chisato is actually a member of the Hero Clan, which is basically a legendary group of warriors sworn to protect humanity from demonic threats. Sounds intense, right? But despite her powerful lineage, Chisato made a conscious choice to step away from battle. Why? Because she values peace and has a natural aversion to violence. Instead of fighting on the front lines, she chose teaching—a path that lets her nurture and guide others in a more peaceful way. And honestly, that says a lot about her character. Even so, her fellow clan members still hold her in high regard. Why? Because Hasegawa Chisato isn’t just smart—she’s strategic, insightful, and incredibly intelligent.
But—and this is where things get interesting—Hasegawa Chisato isn’t quite what she seems at first glance. As the series unfolds, we start to see that she’s operating with a hidden agenda. Shockingly, she’s been secretly collaborating with the demons. At first, it’s confusing—why would someone so protective of others align with their enemies? Well, the truth comes out later in the series: Hasegawa Chisato is driven by a desire for revenge against the Hero Clan itself, motivated by past betrayals and injustices. It’s a major twist, and it completely reshapes how we view her.
Even after this villainous turn, though, Hasegawa Chisato never loses that magnetic charm. She remains captivating, complex, and layered—far from a simple “good” or “bad” character. In fact, that duality is exactly what makes her so intriguing. She’s not just a teacher, not just a warrior, not just a traitor—she’s all of these things, wrapped into one fascinating individual.
So, to sum up, Hasegawa Chisato is a standout character in The Testament of Sister New Devil. From her initial appearance as a flirty, affectionate teacher to her eventual reveal as a woman with deep emotional wounds and a personal vendetta, she evolves in ways that keep viewers hooked. And even when she walks the darker path, her personality stays compelling. No wonder Hasegawa Chisato remains a fan favorite—she’s beautiful, mysterious, and full of depth.
Now, if we dive into personality types, Hasegawa Chisato fits the ESFJ mold pretty well—Extroverted, Sensing, Feeling, Judging. These individuals are known for being warm, social, and deeply nurturing, and that description lines up perfectly with Hasegawa Chisato’s protective instincts and her genuine concern for others. She’s the kind of person who remembers the little details, anticipates needs before they’re voiced, and steps in without hesitation. That’s classic ESFJ behavior.
She’s also highly practical and observant—traits linked to the sensing function. Whether she’s disarming traps or navigating dangerous situations, Hasegawa Chisato relies on her sharp mind and attention to detail. She doesn’t just react; she analyzes, plans, and executes with precision. And when it comes to decision-making? Emotions and values guide her.

This type thrives on being needed and appreciated, often going out of their way to support others emotionally and physically. And let’s be real—that’s Hasegawa Chisato in a nutshell. Her entire motivation revolves around helping Basara, his family, and his friends. She offers comfort, guidance, and even physical protection when necessary. She’s not helping for recognition; she does it because she genuinely wants to make a difference in their lives.
At the same time, there are noticeable traces of Enneagram Type 6—the Loyalist. This aspect shows up in her deep-seated need for security and her fierce loyalty to those she trusts. She worries, yes, but it’s because she cares so much. She seeks stability and often looks to trusted figures for direction, especially when facing uncertainty.
