After many years, the Demon Slayer Corps is about to face off against the infamous Muzan Kibutsuji once again, a confrontation that the Hashira – the elite members of the Corps – have been preparing for a long time. Kimetsu no Yaiba: Infinity Castle will showcase the high-stakes battle between Muzan’s forces and the Demon Slayers as humanity’s survival hangs in the balance.
In the final episode of Kimetsu no Yaiba Season 4, Muzan recalls the tragic past of Tamayo, reminding viewers of the horrific acts she committed, including the massacre of her own family after becoming a demon. All these events transpired during Japan’s Heian period, which lasted from approximately 794 to 1185.
Interestingly, this period also coincides with the timeline of Jujutsu Kaisen, where Sukuna is actively operating. As these powerful beings engage in a battle between Muzan and Sukuna, how will their interactions unfold?


One fan expressed their thoughts: “I forgot about Muzan during the Heian era. Could he team up with Sukuna, or would they despise each other? A clash between these two powerful beings would be truly spectacular.”
“If Muzan maintains a neutral stance and avoids Sukuna, there might be no reason for them to pay attention to each other, or they could even interact cooperatively,” replied another fan.
Both Muzan and Sukuna are formidable entities bound by different goals and rules. Sukuna is a curse seeking to exterminate Jujutsu sorcerers, thriving on chaos and destruction, while Muzan aims to consolidate power and control as much as possible.
However, these objectives do not necessarily conflict or create animosity between them. Their approaches could function within different frameworks. Nevertheless, Sukuna has the potential to eradicate Muzan, as the level of strength in Jujutsu Kaisen far surpasses that in Kimetsu no Yaiba.

Ultimately, there is only one method to resolve this matter definitively. That is for the creators, Gege Akutami and Koyoharu Gotouge, to establish a crossover between their two respective universes. In the end, who will emerge victorious, as this collaboration would certainly generate significant buzz and capture the fervent interest of fans everywhere.
