By the end of this article, you’ll gain a deeper appreciation for Demon Slayer. Let’s dive in together!
Why Zenitsu Didn’t Fall into the Infinity Castle
In the Infinity Castle Arc of Demon Slayer, we see most of the main characters get drawn into the Infinity Castle. However, there’s no scene showing Zenitsu Agatsuma falling in. Unlike the others, he’s treated differently, and many fans have noticed this inconsistency. In this post, we’ll explore why Zenitsu didn’t fall into the castle and what it means for his character.
What stands out about Zenitsu is that while other characters were suddenly sucked into the castle, Zenitsu seemed to act of his own will. This scene’s subtle hint lies in the letter Zenitsu received, which played a significant role in his actions.
The Meaning Behind the Letter Zenitsu Received
In the story, Zenitsu receives a letter from Chuntaro, his sparrow, during his training. This letter was the critical factor that influenced Zenitsu’s actions. It’s clear that his demeanor changed after receiving it.
While the letter’s contents aren’t explicitly shown, it’s clear it had a profound impact on Zenitsu. Fans speculate that it was about his mentor, Jigoro Kuwajima, who was like a father figure to him and taught him Thunder Breathing. This letter likely fueled Zenitsu’s resolve and set him on a new path.
Jigoro Kuwajima and Thunder Breathing
Jigoro Kuwajima was a former Hashira of the Demon Slayer Corps and a master of Thunder Breathing. He was one of the few swordsmen who could use all the forms of Thunder Breathing, and he rigorously trained Zenitsu.
Although Zenitsu could only master the First Form, Jigoro was always watching over his growth. After losing his right leg in battle, Jigoro retired from the Demon Slayer Corps and dedicated himself to training Zenitsu and Kaigaku. To Zenitsu, Jigoro wasn’t just a mentor but also an emotional anchor.
It’s likely that the letter contained news about Jigoro, shaking Zenitsu to his core. This would explain his determination and the decision to head into the Infinity Castle on his own terms.
The Relationship Between Zenitsu and Kaigaku
Zenitsu shared his training with Kaigaku, another disciple of Jigoro. Kaigaku was taught all the forms of Thunder Breathing and, unlike Zenitsu, took his training seriously. While Zenitsu affectionately called Jigoro “Grandpa” and was often running away from training, Kaigaku showed respect, referring to Jigoro as “Master.”
However, Kaigaku’s seriousness was likely driven by pride rather than genuine respect. His motivation was more about proving his strength than truly honoring Jigoro.
This relationship constantly weighed on Zenitsu, pushing him to grow. When Zenitsu received the letter, he clearly understood his role and responsibilities, which ultimately led him to decide to head into the Infinity Castle willingly.
Zenitsu’s Resolve and His Interaction with Tanjiro
After receiving the letter, Zenitsu became uncharacteristically quiet, a sharp contrast to his usual boisterous personality. Noticing this, Tanjiro Kamado asked what had happened, but Zenitsu only replied, “I’ve just made up my mind.” His focus shifted entirely to his mission.
Zenitsu’s expression in that moment was completely different from his usual self—serious and determined. The once noisy, light-hearted Zenitsu had suddenly become quiet, fully committed to his cause. This change clearly reflected the letter’s significance in shaping his mindset.
Why Zenitsu Entered the Infinity Castle of His Own Will
In the end, while other characters were forcibly drawn into the Infinity Castle, Zenitsu entered by his own decision. The letter and his personal resolve seem to be the key reasons for this.
For Zenitsu, entering the Infinity Castle wasn’t just another mission as a Demon Slayer; it was a deeply personal journey driven by his sense of duty to Jigoro Kuwajima and his own self-determination. The letter provided clarity on his mission and set him on this path.
