Demon Slayer’sTanjiro Kamadois one of anime’s strongest protagonists, with unbreakable motivation and diligence to continue training until his technique and swordsmanship are perfect. Over the course of the series, he has slayed a multitude of demons,reaching nearly Hashira levels of ability and power.In the final arc, the hero even becomes a demon for a brief time.

As a demon, Tanjiro was nearly unstoppable. With sharp fangs, tentacles protruding from his back, and the ability to regenerate seemingly instantaneously,the demon version of Tanjirowas a force to be reckoned with. Had he stayed a demon longer, he could have become one of the best and most deadly inDemon Slayer.

However, he did haveone critical weakness: his uncontrollable demon instincts.Shortly after Muzan transformed him into a demon, Tanjiro flew into a frenzy. The unstoppable demon urges caused Tanjiro to attempt to attack every human in the vicinity indiscriminately, even though they were his loved ones.

Shortly following Tanjiro’s Transformation, he was overcome by his demon instincts and unable to do anything but lash out at his friends. His friends fed him a special medicine to quell his demon instincts, turned him human again, and stopped him from mindlessly slaughtering them, so his time as a demon was short-lived. Other demons inDemon Slayerface this same issue of feeling powerless against the biological urge that pushes them to consume human flesh, even if that means hurting someone they love. For one demon, though,her demon instincts are not all-encompassing, and resisting them is possible.

Demon Slayer’s Nezuko Could Have Been the Series' Strongest Hashira

After being turned into a demi-demon, Nezuko exhibited a skill and fearlessness that belied her youth. It also suggests she is prime Hashira material.

Nezuko Kamado, Tanjiro’s sister who has been a demon since the beginning of the series,has been able to control these demon urges completely, for the most part. There were a few moments where Nezuko lost control of herself briefly, but she was always able to be reasoned with and realized her mistake pretty quickly. Tanjiro does not seem to exhibit this level of self-control, and neither did any other demon in the series. Nezuko’s exceptional willpower to prevent herself from harming others is completely unique to her, and this skill, coupled with her sunlight resistance, makes her the most unique demon to ever live.

Even When Nezuko Faces Temptation, She Stops Herself or Is Stopped by Others Before Causing Serious Harm

Nekuzo is certainly frequently tempted to bite humans, and her brother,Tanjiro helps her tremendously with resisting these urges.Urokodaki, Tanjiro’s teacher who also sometimes watches over Nezuko while Tanjiro is preoccupied with his tasks as a member of the Demon Slayer Corps, also shaped Nezuko’s mindset, hypnotizing her to not see humans as enemies or something that can be eaten. Tanjiro’s assistance combined with Urokodaki’s hypnotization aided Nezuko in developing a determination not to eat humans. She is rarely truly tempted beyond the limits of what she can handle, although there are a few instances that were difficult for her to resist.

Tanjiro also kept Nezuko safely secured in a wooden box on his back most of the time, not just because it protected her from sunlight, but because it prevented her from facing temptation to eat any people they may encounter. She also wore a bamboo muzzle in her mouth at all times, as another preventative measure.Tanjiro and Nezuko took every precaution to stop any unfortunate incidentsfrom occurring and to give Nezuko the best possible chance of success against her demon instincts. In the Entertainment District arc, though, she faced her most powerful urge yet, when she encountered an injured, bleeding woman.

Even the Demon King, Lord Muzan, Does Not Possess the Determination and Sunlight Immunity She Does

The scent of blood was nearly too much for Nezuko to withstand, and she lunged towards the woman hungrily. Tanjiro captured her and placed a wooden stick between her fangs, coaxing her to stop before she made an irreversible mistake. Upon realizing what she was about to do to an innocent human, Nezuko burst into tears of grief. Thus, even when her demon instincts are at their most prominent,Nezuko’s humanity is still present and able to be called upon. For Tanjiro, and other demons who have transformed, there is no stopping them once they reach a feral, hungered state.

Demon Slayer’s Finale Reveals Nezuko’s HUGE Secret

The final episode of Demon Slayer’s Swordsmith Village arc has revealed a new fact about Nezuko that will radically alter events from this point on.

Nezuko also faced people deliberately attempting to cause her to slip up and succumb to her instincts, such as Sanemi Shinazugawa, the Wind Hashira, who waved his blood directly in her face and even physically injured her, stabbing her multiple times. DespiteSanemi’s cruel attempts to unleash Nezuko’s demon side, she proved her shatterproof resolve and did not bite or harm Sanemi in any way. Nezuko is no average demon, and her unmatchable willpower makes this fact abundantly clear. Aside from her determination not to eat humans, her sunlight resistance also sets her apart from every other demon inDemon Slayer.

Nezuko’s Resistance Differentiates Her From the Series’ Other Demons

Her Distinctive Skills and Boundless Determination Prove That Her Humanity Is Still Strong Within Her

At the end of the Swordsmith Village arc,Nezuko shocked everyone by walking freely in the sunlightwithout sustaining a single injury or burn. Sunlight is usually a demon’s kryptonite, so it was significant that Nezuko managed to conquer the natural element. Muzan, the progenitor of all demons, immediately began plotting to steal Nezuko’s newfound immunity for himself, since being able to stand in the sun unscathed is such a rarity among demons. Not only can Nezuko resist her demon instincts, she can also resist the sun itself, making her as close to unstoppable as a demon can get.

Nezuko is no average demon, andher sunlight resistanceand willpower that prevents her from consuming humans prove this fact. Her Blood Demon Art and body are indeed strong, butNezuko’s will is her true weapon. She continued to cling to her humanity adamantly, refusing to succumb to the demon powers taking over her body. Other demons who were transformed by Muzan fell completely under his control, but, frustratingly for the Demon King, Nezuko was not so easy to sway.Nezuko KamadoisDemon Slayer’sstrongest, most unique, and most self-disciplined demon, with unmatched skills no other character can replicate.
