Atsushi Sendo, better known as “Akkun,” is a standout character in the popular anime and manga series Tokyo Revengers. He’s a core member of the Tokyo Manji Gang—a group of delinquent youths that the main protagonist, Takemichi Hanagaki, becomes deeply involved with over time. Now, when you first meet Akkun, you might notice how quiet and intense he comes across. But don’t let that silence fool you—Akkun has a fearsome reputation, both for his combat skills and his no-nonsense attitude.

Over the course of the series, Atsushi Sendo “Akkun” proves himself to be one of the most dependable members of the gang. You’ll often catch him hanging around with other key figures, especially Ken Ryuguji—better known as Draken—who happens to be his closest friend. Their bond is strong, and Akkun’s loyalty runs deep. Sure, on the outside, he looks tough, maybe even intimidating, but beneath that hardened shell is someone who genuinely cares about his comrades. In fact, Akkun will go to great lengths to protect the people he values, even if it means putting himself on the line.

And speaking of protection, Akkun doesn’t just rely on brute strength—he’s got serious fighting chops. His weapon of choice? A trusty baseball bat, which he wields with precision and power. It’s not just about aggression, though. There’s a method to his actions. Whether he’s assessing a threat or stepping in during a fight, Akkun thinks things through. This makes him not only a skilled fighter but also a strategic presence within the Tokyo Manji Gang.

Now, looking at Akkun’s personality more closely, it’s clear that Atsushi Sendo embodies many traits associated with the ISTJ personality type. He’s practical, disciplined, and highly detail-oriented. While others might get caught up in emotions or abstract ideas, Akkun stays grounded in reality, focusing on what needs to be done. He’s not one to speak unless necessary, but when he does, his words carry weight. That quiet reliability? It’s part of what makes Akkun such a trusted figure among his peers.

His ISTJ nature also shows in how he approaches responsibilities. Whether it’s watching out for potential dangers or supporting Draken in leadership decisions, Akkun never shirks his duties. He observes carefully, plans ahead, and sticks to proven methods rather than taking unnecessary risks. Tradition and structure matter to him, and this consistency helps anchor the group during turbulent times.

Then there’s the Enneagram angle—many fans believe Atsushi Sendo “Akkun” fits the profile of Type 8, the Challenger. And honestly, it makes a lot of sense. Akkun has a strong need for control, especially when it comes to protecting those close to him. He doesn’t back down from confrontation and isn’t afraid to challenge authority when he feels something’s wrong. This rebellious streak can make him seem hot-headed at times, and yes, he can act impulsively—especially when provoked.

But here’s the thing: behind that aggressive front lies a deeper fear of vulnerability. Akkun keeps his softer emotions under wraps, revealing them only to a select few. That emotional guardedness is classic Type 8 behavior. He’d rather come off as tough than risk being hurt or controlled by others. Yet, paradoxically, this same drive fuels his fierce protectiveness toward friends like Draken and the rest of the gang.

So, putting it all together, Atsushi Sendo “Akkun” emerges as a layered, compelling character whose actions are rooted in loyalty, duty, and a desire for autonomy. From his role in the Tokyo Manji Gang to his psychological profile, Akkun consistently demonstrates strength—not just physically, but emotionally and mentally too. Whether you’re analyzing his ISTJ tendencies or his Enneagram Type 8 traits, one thing remains clear: Akkun is far more than just a silent enforcer. He’s a crucial pillar in Tokyo Revengers, and characters like Atsushi Sendo help elevate the story’s depth and intensity.
