The Demon Slayer Corps is an organization that exists in the anime and manga series, and their task is to get rid of all demons and help humanity survive. Demons wreak havoc, all thanks to Muzan’s ability to turn any human into one of his lackeys. However, there is one person in the organization whose efforts cannot be overstated. That person is none other than Kagaya Ubuyashiki. He was introduced in the first season of the anime series. 

Kagaya Ubuyashiki is the leader of the Demon Slayer Corps, and every member has the utmost respect for him. He is extremely frail in the series, and he is incapable of fighting on the battlefield. He doesn’t even have the strength to swing a sword, let alone decapitate a demon. However, fans who are up to date with the anime will know just how valuable he was to the organization. 

His main task is to assign the demon hunters to areas affected by the presence of demons. He died quite young, and even in his final moments, he showed nothing but strength. The juxtaposition between his strength and his gentle demeanor is why he is so popular among fans. Let’s take a closer look at the character to understand more about him. 

Kagaya Ubuyashiki’s Background in Demon Slayer

Kagaya Ubuyashiki’s appearance is due to his condition. All male members of the bloodline are cursed, and they die quite young. This is because of his connection to Kibutsuji Muzan. The Demon King was born in the same family, and therefore, the Ubuyashiki clan is cursed. Furthermore, this curse would only be lifted when Muzan dies. The priest had selected Amane to be his wife. However, Kagaya refused to marry her unless she did so of her free will. Following their marriage, they gave birth to five children. 

He first encountered Gyomei Himejima when he was just 14 years old. He realized that there was a misunderstanding, and he intervened immediately. Therefore, he freed the blind monk who was accused of killing children. He went on to become the Stone Hashira, the most powerful demon hunter of his generation. 

Following that, one by one, he gathered strong demon hunters. He was an exceptional leader, and he commanded a great deal of respect. Kagaya Ubuyashiki had some of the most elite fighters in the plenty, and they would sacrifice their lives to save him and other human beings. He quite literally built a team of demon hunters who would go on to defeat Muzan towards the end of the manga.

Kagaya Ubuyashiki’s Abilities in Demon Slayer

The leader of the Demon Slayer Corps has an innate ability to mask his true emotions. No matter what the external stimulus is, he has a stoic and gentle demeanor. He doesn’t show any spike in emotions and always keeps a level head. This can be seen when Muzan visits Ubuyashiki in his own mansion. The latter is on his deathbed, and despite meeting the one person he detests, Ubuyashiki maintains a calm demeanor. This shows the level of emotional control he has. Furthermore, he has a very soothing voice that puts people at ease. 

Tanjiro noticed this when he first encountered the leader. However, Kagaya Ubuyashiki’s most impressive ability is his foresight. This ability has quite literally saved thousands of lives because he assigned the right amount of demon hunters to areas where powerful demons would eventually appear.

There were dire consequences if he didn’t assign just the right amount of demon hunters to any mission. Assign more than what’s required, and the organization becomes understaffed should another demon attack break out. If he didn’t send enough demon hunters, it would lead to the deaths of those in the mission while the demon continues to live. His foresight played an important role in minimizing deaths and helping the Corps defeat some of the strongest Upper Moon demons. He laid the foundations for the demon hunters to progress and eventually kill Muzan in the manga series.

He took on the role of a side character who was monumental in the progression of the plot. Kagaya Ubuyashiki worked in the background and ensured that the demon hunters always had the best chance when they were up against demons. He didn’t receive much screen time, and he died quite young. However, he showed just how tough he was in this short time frame. 

As a leader of the Corps, he didn’t even know how to swing a sword. However, he is one of the most important characters who had a profound impact on everyone he worked with, and it ultimately led to Muzan’s death. His children showed incredible amounts of resilience as well. Fans were happy to see that Ubuyashiki spent a short yet fulfilling life and that his wishes came true.

Kagaya Ubuyashiki only had one male child, and he was Kiriya. Since the eldest male members are the successors, Kiriya was forced to take this position after his father’s death. Kiriya had to guide the demon hunters who were scattered in the Infinity Castle. He saw demon hunters die and felt the immense pressure. He realized just how effortless his father made it look. Kiriya was young, and despite the unending pressure, he valiantly carried on. He displayed incredible character and continued despite facing a myriad of setbacks. 

When Muzan finally died, he was filled with joy. It is interesting to note that Kiriya Ubuyashiki went on to become the oldest living human in Japan. In fact, a reporter attempted to interview him. The curse that the Ubuyashiki Clan was afflicted with ceased to exist. 

Conclusion

Kagaya Ubuyashiki is one of the most beloved characters in the series. He is one of those characters who fans unanimously love. He was the leader of the Demon Slayer Corps and led a generation of demon hunters who managed to kill Muzan. His efforts had a lasting impact since humanity prevailed, and they no longer had to worry about dying to demons.
