Who Is Kaigaku in Demon Slayer?
Kaigaku is introduced as a former disciple of the Thunder Hashira, and his role as a disciple brings with it high expectations. As a young swordsman under Zenitsu Agatsuma, Kaigaku had the potential to become an incredible warrior. However, unlike his fellow disciples, Kaigaku’s ambitions led him down a dark path.
While Zenitsu continues to struggle with his self-doubt and fears, Kaigaku harbors jealousy and disdain for him. He feels inferior and often expresses resentment towards Zenitsu, believing that he should be the one to inherit the Thunder Breathing techniques, not Zenitsu. His inner turmoil is compounded by the harsh training, and eventually, Kaigaku’s yearning for power leads him to betray his mentor and abandon the Demon Slayer Corps in favor of the demons.
Kaigaku’s fall from grace is both heart-wrenching and infuriating, making him a truly tragic villain. His shift from a disciple of righteousness to an antagonist reveals the dangers of ambition and unchecked desires. His storyline serves as a crucial part of Zenitsu’s character development and understanding of strength.
Reminder: Keep in mind that Kaigaku’s actions are deeply influenced by his insecurities and the environment he was in.
Why Does Kaigaku Betray His Mentor and Become a Demon?
Kaigaku’s betrayal of Zenitsu and the Demon Slayer Corps can be traced back to his internal conflict and desire for power. Unlike Zenitsu, who possesses innate potential but lacks confidence, Kaigaku is driven by a need to prove himself. The pressure of living up to the expectations of his mentor, Zenitsu, and the Demon Slayer Corps ultimately breaks him.
The turning point for Kaigaku is his encounter with the demons. After feeling neglected and overlooked, Kaigaku meets Kokushibo, a high-ranking demon in the Twelve Kizuki, who offers him the power he desperately seeks. The temptation of power is too great for Kaigaku to resist, and he betrays everything he once stood for to become a demon. His transformation into a demon represents not just a physical change but also a deep moral fall.
Once Kaigaku becomes a demon, his personality changes drastically. His desire for power intensifies, and his hatred for Zenitsu grows. In his demon form, Kaigaku becomes more dangerous, fueled by his resentment towards his former comrades and mentor.
| Stage | Characteristic Before Transformation | Characteristic After Transformation |

Note: Remember that Kaigaku’s transformation wasn’t just physical—it was a change in his very essence.
What Is the Impact of Kaigaku on Zenitsu?
One of the most significant impacts Kaigaku has in the series is on Zenitsu. Despite their differences and Kaigaku’s betrayal, Zenitsu plays a crucial role in Kaigaku’s eventual defeat. Zenitsu’s journey of growth is deeply tied to Kaigaku’s betrayal, as Zenitsu grapples with his emotions of anger, disappointment, and ultimately, acceptance.
Zenitsu’s conflict with Kaigaku comes to a head during their battle, where Zenitsu faces his former mentor, now a demon. The fight is not just a physical one but an emotional and psychological one as well. Zenitsu must confront the painful reality that his mentor, who he once looked up to, is now an enemy. Zenitsu’s struggle to overcome his fear and doubt during this battle marks a significant moment in his character development, showing how far he has come from the timid, cowardly figure he once was.
