Hajime Arisu is the main protagonist of the popular Japanese manga and anime series Alice in Borderland, a gripping story set in a mysterious, alternate version of Tokyo. In this intense world, a group of teenagers suddenly find themselves thrust into life-or-death games where survival depends on wit, courage, and strategy. Hajime Arisu—often called Arisu by those close to him—is a passionate gamer who ends up navigating this dangerous new reality alongside his loyal friends Karube and Segawa. Right from the start, Hajime Arisu stands out as someone deeply connected to virtual challenges, but when real stakes replace digital ones, he’s forced to adapt in ways he never imagined.

At first glance, Hajime Arisu comes across as laid-back, even a bit reckless, enjoying the thrill of games without much concern for consequences. But as the series unfolds, we see a significant transformation in Hajime Arisu. He gradually evolves into a more responsible and resolute individual, driven not just by the desire to survive, but to find a way back home. What really defines Hajime Arisu, though, is his unwavering loyalty. He consistently puts himself on the line to protect his friends, showing emotional depth and moral strength that grow stronger with each trial.

One of the key reasons Hajime Arisu manages to endure the deadly trials of the Borderland is his sharp mind and gaming expertise. His deep understanding of game mechanics and strategic thinking gives him an edge in high-pressure situations. Yet, it’s not all about logic and reflexes—Hajime Arisu also faces intense internal struggles. As the brutal realities of the Borderland sink in, he begins questioning his own values, confronting the darker aspects of human nature, including his own. This inner conflict adds layers to Hajime Arisu’s character, making his journey not just physically demanding, but emotionally profound.

All in all, Hajime Arisu is a compelling and multi-dimensional protagonist whose evolution throughout Alice in Borderland keeps viewers deeply engaged. From a carefree gamer to a courageous survivor, Hajime Arisu embodies resilience, intelligence, and heart—qualities that make fans root for him every step of the way. His experiences highlight themes of friendship, morality, and personal growth, solidifying Hajime Arisu as a standout character in modern anime storytelling.

When it comes to personality typing, Hajime Arisu fits the ISTP (Introverted-Sensing-Thinking-Perceiving) profile quite well. ISTPs are typically practical, observant, and highly independent—traits that resonate strongly with Hajime Arisu. He relies on real-time analysis and hands-on experience rather than abstract theories, which allows him to react swiftly in unpredictable scenarios. Whether it’s dodging traps or outsmarting opponents, Hajime Arisu consistently demonstrates the calm, logical mindset characteristic of an ISTP.

Moreover, ISTPs often thrive in action-driven environments, and Hajime Arisu is no exception. He doesn’t shy away from danger; in fact, he seems to excel under pressure. His willingness to take risks and dive headfirst into perilous games reflects the adventurous spirit typical of this type. Even in chaotic battles, Hajime Arisu remains focused, using his keen senses and quick reflexes to gain the upper hand.

Another hallmark of the ISTP type is a reserved social demeanor, and Hajime Arisu clearly exhibits this. He tends to stay quiet during group discussions, carefully observing others before making his move. Rather than seeking attention, Hajime Arisu prefers to act decisively when the moment calls for it. This thoughtful, behind-the-scenes approach reinforces his image as a quiet strategist—one who leads through actions, not words.

Looking at the Enneagram, Hajime Arisu strongly aligns with Type 8, known as the “Challenger.” These individuals are assertive, confident, and driven by a need for autonomy and control. Hajime Arisu consistently takes initiative in crises, stepping up as a natural leader when others hesitate. He doesn’t wait for permission—he assesses the situation and acts, often putting himself at risk to shield his companions.

His strong sense of justice and protective instincts further support the Type 8 classification. While Hajime Arisu may come off as tough or even confrontational at times, his aggression usually stems from a place of defense—especially when those he cares about are threatened. That said, his desire for control can occasionally lead to friction, particularly when others challenge his decisions. This stubborn streak, while sometimes problematic, underscores his determination and unwillingness to back down.

In summary, Hajime Arisu emerges as a complex blend of traits that reflect both the ISTP personality type and Enneagram Type 8. His analytical mind, bold decision-making, and quiet leadership define his role in Alice in Borderland. Whether he’s solving puzzles, facing down enemies, or grappling with moral dilemmas, Hajime Arisu remains a central figure whose journey captivates audiences. Through every challenge, Hajime Arisu proves time and again why he’s not just a survivor—but a hero shaped by fire.
