So, let’s talk about Arjuna—a central figure in the anime Problem Children Are Coming from Another World, Aren’t They?—and really dive into what makes him such a compelling character. Arjuna is one of the three so-called “problem children” brought from Earth to the fantastical realm known as Little Garden, and right from the start, he stands out. He’s quiet, composed, and carries himself with a kind of calm intensity that immediately draws attention. Physically, Arjuna is incredibly strong—his background in martial arts gives him an edge—but what truly sets him apart is his ability to control fire, a power that’s both awe-inspiring and deeply personal.

Now, at first glance, Arjuna might come across as distant or even cold. He doesn’t open up easily and tends to keep others at arm’s length, especially early on. But over time—and this is where things get interesting—Arjuna begins to show more of himself. As he spends more time in Little Garden and bonds with his fellow problem children, You Kasukabe and Izayoi Sakamaki, he slowly starts to lower his guard. And honestly, it’s pretty rewarding to watch that transformation unfold.

Digging deeper into his past, we learn that Arjuna comes from a long line of martial artists, which explains his discipline and physical prowess. But there’s also a tragic layer to his story: the loss of his sister in a fire during his childhood. That event has clearly left a deep mark on him. It’s no wonder, then, that his flame-manipulating abilities stir up such complex emotions—fascination mixed with fear, power shadowed by guilt. Arjuna constantly wrestles with how to wield his gift responsibly, always mindful not to hurt anyone the way he was hurt.

Throughout the series, Arjuna proves himself again and again as a dependable and courageous ally. Whether it’s stepping into a dangerous battle to protect innocent people or standing firm against corrupt authority, he consistently acts on his principles. His actions speak volumes about who he is—not just as a fighter, but as a person. And speaking of personality, many fans and analysts alike have noted that Arjuna fits the INFJ type remarkably well.

INFJs are known for their depth, empathy, and strong moral compass—all traits that Arjuna embodies. He may not wear his heart on his sleeve, but his concern for others runs deep. He’s introspective, often reflecting on his choices and the weight of his power. And when conflicts arise, Arjuna doesn’t just rely on strength; he listens, understands, and seeks solutions that protect the vulnerable. That emotional intelligence, combined with his quiet determination, is classic INFJ behavior.

Moreover, Arjuna’s relationships highlight another side of his personality. While he starts off reserved, his loyalty to You and Izayoi grows stronger with each challenge they face together. He doesn’t say much, but when Arjuna shows up—whether it’s shielding a friend from danger or making a tough call in battle—you know it comes from a place of genuine care and conviction.

From an Enneagram perspective, Arjuna strongly aligns with Type 8: “The Challenger.” This makes a lot of sense when you think about it. Type 8s are assertive, protective, and driven by a need for autonomy and justice—exactly the kind of energy Arjuna brings. He doesn’t back down from threats, he challenges unfair systems, and he takes charge when leadership is needed. At the same time, like many Type 8s, he struggles with vulnerability. Expressing emotions isn’t easy for him, and he’d rather shoulder burdens alone than appear weak.

Still, despite his tough exterior, Arjuna’s core motivation is protection—of his friends, of the innocent, of what’s right. That protective instinct, paired with his internal battles and gradual emotional growth, paints a rich and nuanced portrait of a young man learning to balance strength with compassion.

In the end, Arjuna from Problem Children Are Coming from Another World, Aren’t They? stands out not just because of his powers, but because of who he is beneath them. His journey—from isolation to connection, from self-doubt to purpose—is one of the most compelling arcs in the series. Whether you’re analyzing him through the lens of MBTI or Enneagram, one thing remains clear: Arjuna is a character defined by integrity, resilience, and a quiet kind of heroism that leaves a lasting impression.
