Kaigaku's abilities in 'Demon Slayer' are a fascinating mix of raw power and tragic backstory. As a former disciple of the Thunder Hashira, Jigoro Kuwajima, he was trained in Thunder Breathing, but after turning into a demon, he twisted those techniques into something darker. His signature move, 'Thunderclap and Flash,' is now corrupted with demonic energy, making it faster and deadlier. He also wields a black Nichirin sword that crackles with electricity, a twisted reminder of his human past.
What really stands out is how his arrogance fuels his combat style—he relies on brute force and speed, dismissing finesse. Unlike Zenitsu, who masters Thunder Breathing's first form with precision, Kaigaku skips fundamentals, thinking raw power is enough. It’s poetic how his downfall mirrors his lack of discipline. The way his lightning turns from golden to black symbolizes his moral decay, and honestly, it’s one of the coolest visual metaphors in the series.

In "Demon Slayer", Kaigaku starts out as a student under Zenitsu's master, Jigoro Kuwajima. Kaigaku's story takes a dark turn, however, when he forsakes his life as a Demon Slayer and goes over to the enemy--becoming one of them instead. It is his pursuit for power and his rejection of weakness that spurs this transition.
Being Upper Rank 6 of the Twelve Kizuki, Kaigaku makes for a formidable foe for Zenitsu and is a constant irritation to him both mentally and physically. His character arc serves as a brutal reminder of what happens when power is chosen over human decency.

Kaigaku's backstory is one of those tragic tales that makes you reevaluate how far desperation can push someone. He was originally an orphan, struggling to survive on the streets before being taken in by the former Thunder Hashira, Jigoro Kuwajima. At first, it seemed like he had a chance—training under a master who genuinely cared, even sharing the dojo with Zenitsu. But Kaigaku had this burning resentment, this hunger for power that never got satisfied. He couldn’t stand being second best, especially to someone he saw as weak like Zenitsu. When Muzan offered him strength, he betrayed everything. What gets me is how his pride twisted him—he could’ve been a hero, but instead, he became a demon just to feel superior.
His downfall mirrors so many villains who could’ve been great if they’d just embraced humility. The way he sneers at Zenitsu during their final fight, clinging to his warped ego even in death, is chilling. It’s like the series is saying: talent means nothing without character. And honestly? That’s a lesson that sticks with me way more than flashy sword techniques.

Kaigaku's transformation into a demon is one of the most tragic arcs in 'Demon Slayer.' He was once a fellow disciple under the same master as Zenitsu, but his path diverged sharply due to his desperation and pride. After failing to master Thunder Breathing techniques as quickly as Zenitsu, Kaigaku grew bitter and resentful. When faced with a life-or-death situation against a demon, he chose survival over principles, betraying his master and accepting Muzan Kibutsuji's offer of power.
What makes his fall particularly heartbreaking is how it contrasts with Zenitsu's growth. While Zenitsu overcame his cowardice through sheer determination, Kaigaku succumbed to his flaws. His demon form even reflects this—twisted and corrupted, yet still wielding a perverted version of Thunder Breathing. The way his story intertwines with Zenitsu's final battle adds such emotional weight to their confrontation. It's a brilliant exploration of how similar beginnings can lead to wildly different fates.

Zenitsu and Tanjiro are such fascinating characters in 'Demon Slayer,' but comparing their strength feels like comparing apples and oranges. Tanjiro's growth is steady and grounded in relentless training, while Zenitsu's power bursts forth in explosive moments when he's unconscious. I love how the series portrays their differences—Tanjiro's resilience and adaptability versus Zenitsu's raw, untapped potential. That said, Zenitsu's Thunder Breathing techniques are insanely powerful, especially when he 'sleep-fights,' but Tanjiro's mastery of multiple forms and his ability to think on his feet give him a broader edge.
Honestly, I don't think Zenitsu ever fully surpasses Tanjiro in overall strength, but he definitely has moments where he outshines him in sheer speed and destructive power. Their dynamic is more about complementary skills than one overtaking the other. Tanjiro's the heart of the team, while Zenitsu is the wildcard—both irreplaceable in their own ways.
