In the world of Demon Slayer: Kimetsu No Yaiba, each character leaves a lasting impression, thanks to their distinct personalities and combat skills. Among them, Zenitsu Agatsuma stands out for his eccentric fighting style.
Initially portrayed as a timid individual terrified of demons, Zenitsu surprises viewers with his extraordinary ability to engage in combat while asleep. This duality raises questions about the mechanisms behind his remarkable powers—what allows him to fight in an unconscious state?
Unveiling Zenitsu’s Skill of Fighting While Asleep
The Thunder Clap and Flash Technique

In the series, Zenitsu practices the Thunder Breathing technique, which significantly enhances his speed and allows for rapid, powerful strikes. Unlike others who have mastered multiple techniques within their respective styles, Zenitsu has focused intensely on perfecting a single technique: Thunder Clap and Flash.
Despite having only this one technique in his repertoire, Zenitsu’s exceptional mastery makes him a formidable opponent, deploying astonishing speeds that leave his enemies unable to anticipate his attacks. Intriguingly, he can only unleash this power while he is unconscious.
How Does His Technique Operate?


While it may seem absurd for Zenitsu to engage in battle during sleep, there are scientific possibilities at play. Zenitsu often succumbs to panic upon encountering a demon, resulting in fainting—this response may activate his latent abilities. His proficiency in Thunder Clap and Flash likely stems from extensive training, ingraining the technique into his muscle memory.
You might wonder why his abilities seem to materialize only while he’s asleep. The answer lies in his panic. When awake, fear overwhelms him, limiting his performance. Conversely, in a state of unconsciousness, he transcends these fears, accessing his true potential.
“Don’t ever give up. Even if it’s painful, even if it’s agonizing, don’t try to take the easy way out.” – Zenitsu
This instinctual fighting style allows Zenitsu to rely on his innate skills. Additionally, a significant influence on his abilities can be traced back to his mentor, Jigoro Kuwajima, a former Thunder Hashira. Strikingly, his unique approach mirrors real-life sleeping disorders, such as sleepwalking or REM sleep behavior disorder, wherein individuals act out their dreams.
Exceptional Hearing Capabilities



Zenitsu’s extraordinary sense of hearing plays a crucial role in his combat effectiveness during sleep. In his unconscious state, his auditory perception is significantly enhanced, enabling him to detect even the faintest sounds and distinguish between various auditory stimuli.
This heightened ability not only allows Zenitsu to locate demons with precision but also grants him insight into the emotions and thoughts of others. By attuning to subtle sound differences, he can readily differentiate between humans and demons based on the sounds they produce.
Ultimately, Zenitsu’s unconscious fighting style not only serves as a testament to his latent strength but also underscores his role beyond mere comic relief. Anticipating how he will confront formidable demons with his unique method is an exciting prospect for fans going forward.
