Belial is one of the most captivating characters in Seven Mortal Sins—also known as Sin: Nanatsu no Taizai—and her presence leaves a lasting impression throughout the series. As one of the Seven Demon Lords of Hell, Belial holds the title of the Demon Lord of Vanity, embodying the deadly sin of pride. Her striking appearance only enhances her aura: long silver hair flows down her back, contrasting with her mesmerizing purple eyes, and she wears a sleek, revealing black outfit adorned with golden embellishments that highlight her status and confidence.

Now, when it comes to personality, Belial truly stands out. She’s not just another powerful demon; she’s cunning, seductive, and incredibly intelligent. Belial thrives on manipulation, using charm and psychological insight to bend others to her will. It’s not just about brute strength with her—it’s strategy, timing, and knowing exactly how to exploit weaknesses. And speaking of power, Belial commands control over space and time itself. She can open portals for instant travel across vast distances, slow down time for her enemies, and move with such speed and strength that few can keep up in battle.

But what really makes Belial so intriguing? Well, beyond her flashy abilities and bold demeanor, there’s mystery surrounding her past. While details remain scarce, hints suggest she wasn’t always a demon. Some believe Belial was once a high-ranking angel who fell from grace and embraced demonhood—but why? That part remains unclear. This hidden history adds depth, making fans constantly wonder about her motivations and inner conflicts.

Then there’s her relationship with Lucifer—one of the other Demon Lords. Their dynamic is complicated, to say the least. There’s tension, rivalry, and occasional clashes, yet despite their friction, Belial remains fiercely loyal to the cause of the Demon Lords. When push comes to shove, she’ll do whatever it takes to secure victory in the war for control of Hell. That kind of dedication speaks volumes about her character.

In terms of personality typing, many fans speculate that Belial fits the ESTP profile—often called “The Entrepreneur.” Why? Because Belial radiates confidence, thrives in chaotic situations, and reacts instinctively rather than planning every step. He’s impulsive, loves taking risks, and lives for the thrill of the moment. Whether it’s diving into combat or manipulating an enemy’s emotions, Belial acts fast and adapts even faster. His charisma is off the charts, allowing him to talk his way out of tight spots or persuade allies and foes alike. Sure, this spontaneity can lead to reckless decisions at times, but more often than not, Belial pulls through thanks to quick thinking and nerves of steel.

Looking deeper, some also see signs of Enneagram Type Eight—the Challenger—in Belial’s behavior. This type is all about strength, control, and independence, and Belial checks nearly every box. He doesn’t wait for permission; he takes charge. He trusts his own judgment above all else and isn’t afraid to stand tall in the face of opposition. But here’s the catch: that same drive for dominance can create friction. His reluctance to rely on others or share power might isolate him at times, and his assertiveness can come across as intimidating—or even aggressive—to those around him.

Still, these traits don’t make Belial any less compelling. If anything, they add layers to his character. The mix of raw power, strategic mind, emotional complexity, and mysterious origins makes Belial a standout figure in Seven Mortal Sins. Whether you admire his confidence or question his motives, one thing’s for sure—Belial commands attention wherever he goes.

So overall, Belial isn’t just another villain or ally—he’s a multifaceted force of nature. From his dramatic design to his psychological depth, Belial continues to fascinate fans across the world. And while we may never learn everything about his past, one truth remains: Belial is, without a doubt, one of the most memorable characters in the series.
