Eida, sometimes referred to as Ada, is a character who has made a striking entrance in the world of Naruto, particularly within the newer series Boruto: Naruto Next Generations. As one of the central figures in the Vessel Arc, Eida stands out not just because of her role, but also due to her complex personality and mysterious aura. And honestly, it’s hard to talk about this arc without mentioning Eida—she really shapes the direction of the story.

Visually, Eida makes quite the impression. She’s portrayed as an elegant woman with pale skin, long flowing hair, and those intense blue eyes that seem to see right through you. At first glance, she appears calm and composed, almost serene—but don’t let that fool you. Eida is introduced as part of Kara, a secretive and powerful organization made up of rogue ninja with grand ambitions. Their goal? Nothing less than reshaping the shinobi world. And Eida isn’t just a minor player—she’s got abilities that make her a serious threat.

One of the most fascinating aspects of Eida is her unique power: the ability to manipulate the human brain. That means she can control thoughts, beliefs, even actions—all with a mere gaze. It’s no wonder people fear her. In fact, Eida’s presence alone can shift the balance of power. Her demeanor is often cold and calculated, always focused on her objectives. But here’s the thing—while she may come across as purely villainous at first, there’s more beneath the surface. Eida carries a tragic past, which adds layers to her character and makes her more than just a typical antagonist.

Throughout the Vessel Arc, Eida plays a crucial role in pushing the narrative forward. Every move she makes ripples across the storyline, affecting key characters in profound ways. As the plot unfolds, we begin to understand her motivations better—what drives her, what she hopes to achieve. And let’s be honest, the way her arc concludes? Totally unexpected. It’s moments like these where Eida truly shines as a character—complex, unpredictable, and deeply compelling.

Now, if we dive into personality types, Eida fits the ISTP profile in the MBTI framework pretty well. She’s logical, practical, and tends to rely on facts rather than emotions when making decisions. You’ll notice she doesn’t get caught up in dramatics; instead, she observes, analyzes, and acts with precision. Independence is key for Eida—she prefers working solo and seems uncomfortable in group settings, especially when emotions run high. Her introverted nature means she keeps to herself, carefully watching others without revealing much in return. All of this points toward a classic ISTP mindset—someone who values efficiency, autonomy, and real-world solutions.

Then there’s the Enneagram angle. Eida strongly resonates with Type 4, known as the Individualist or the Romantic. This type craves authenticity and deeply fears being ordinary. And yeah, that’s totally Eida. She wants to be seen as unique, special—someone who stands apart from the crowd. Her introspective nature, emotional depth, and artistic expression (like poetry) are all hallmarks of a Type 4. There’s also a sense of longing in her character—a desire for connection, yet a simultaneous withdrawal from others. It’s a painful paradox, really.

But wait—there’s more. Eida also shows signs of Type 5, the Investigator. She’s intellectually sharp, curious about how things work, and highly self-reliant. Her tendency to detach emotionally and avoid deep personal bonds aligns with the Five’s need for control and knowledge over intimacy. So while her core leans heavily toward Type 4, that analytical, reserved side pulls her toward Type 5 traits as well.

Putting it all together, Eida emerges as a multi-dimensional character whose actions and psyche are shaped by a blend of individualism, intellect, and inner turmoil. Whether you call her Eida or Ada, one thing’s clear—her impact on the Naruto universe is undeniable. She challenges heroes, bends reality, and forces everyone—including the audience—to question motives and morality. And while personality typing isn’t an exact science, the patterns in Eida’s behavior make her a standout example of both ISTP logic and Enneagram Four depth. Honestly, it’s hard to imagine the Vessel Arc without her—Eida doesn’t just play a role, she defines it.
