Jo is one of the main characters in the anime series Burst Angel, originally known in Japan as Bakuretsu Tenshi. As a central figure in the story, Jo stands out not just for her physical prowess but also for her quiet intensity and unwavering resolve. She shares the spotlight with Meg, serving as the second protagonist and often stepping into the role of the team’s powerhouse—both literally and figuratively. When danger arises, it’s usually Jo who steps forward, ready to take on any threat with unmatched strength, agility, and sharp tactical thinking.

Though details about Jo’s past remain somewhat mysterious, there are hints that she spent her early years in an orphanage before enlisting in the military. From there, she rose through the ranks and eventually became part of an elite covert unit called RAPT—the Rapid Armed Police Taskforce. This background helps explain her disciplined combat style and deep understanding of weapons and strategy. Her time in RAPT clearly shaped her into the formidable fighter she is throughout the series.

In terms of personality, Jo comes across as stoic and reserved, rarely showing emotion or indulging in idle conversation. But beneath that calm exterior lies fierce loyalty and a strong protective instinct toward those she considers allies. It’s clear that while Jo may seem distant at first, she deeply values the people she fights alongside. Her weapon of choice? A pair of large, powerful handguns that she wields with incredible precision. Whether using standard rounds or specialized ammunition like explosives, Jo demonstrates mastery over her gear, making her a force to be reckoned with in any battle.

Throughout Burst Angel, Jo consistently proves herself as one of the most capable fighters in the cast. Opponents often fall quickly under her overwhelming skill and confidence. Yet, despite her strength, Jo isn’t without inner conflict. She grapples with memories of her past and the weight of her actions, especially those tied to her military service. Still, what defines Jo most is her sense of justice and dedication to protecting others—qualities that make her not only powerful but also profoundly human.

When looking at personality frameworks, Jo fits well within the ISTP type according to the Myers-Briggs system. He approaches problems logically, thinks quickly under pressure, and prefers to act rather than talk. Independence is key for Jo—he works best alone and only teams up when absolutely necessary. His hands-on expertise with mechanics and technology further supports this classification, highlighting his preference for practical solutions over abstract theories. He avoids unnecessary risks and focuses on what works, which is classic ISTP behavior.

That said, Jo also shows a rebellious side, frequently resisting authority and rejecting societal rules he views as flawed or oppressive. This defiance might reflect a weaker Fe (extraverted feeling) function, common in ISTPs, where emotional expression and social harmony aren’t natural strengths. While he may struggle with connecting emotionally, his actions speak volumes—especially when it comes to defending those he cares about.

From an Enneagram perspective, Jo appears to align closely with Type 8: “The Challenger.” This type thrives on control, autonomy, and direct action—all traits evident in Jo’s demeanor and decisions. He doesn’t wait for permission; instead, he takes charge, especially in high-stakes scenarios. There’s a competitive edge to him, along with a readiness to confront injustice head-on. At times, Jo can come off as aggressive or emotionally guarded, pushing others away to maintain his independence. But again, this toughness often serves as a shield for deeper protective instincts.

Ultimately, Jo’s portrayal in Burst Angel combines raw power with psychological depth. Whether analyzed through MBTI or Enneagram lenses, his character reflects a complex blend of self-reliance, resilience, and quiet devotion. While personality typing isn’t set in stone, both ISTP and Type 8 offer meaningful insights into who Jo is. And even without labels, one thing remains certain: Jo plays a vital role in the series, bringing strength, skill, and emotional gravity to every scene he’s in.
