Is Zenitsu Agatsuma a Pillar? Revealing the truth about whether he becomes the Thunder Pillar in the Demon Slayer ending

In the epic story of "Demon Slayer," fans have witnessed many characters' bloody battles and astonishing growth. Among them, Zenitsu Agatsuma transformed from a cowardly swordsman who only cried and ran away into a strong individual capable of standing on his own. His final strength and status have become a hot topic of discussion among fans. Many are curious: with his remarkable achievement of single-handedly killing an Upper Rank demon, did Zenitsu Agatsuma ultimately ascend to the highest hall of the Demon Slayer Corps and become a member of the "Hashira"? The answer, in fact, lies in the recognition of his strength and the reality of the story's conclusion.

Conditions for Becoming a "Hashira"

First, we must understand the strict conditions for becoming a "Hashira" in the Demon Slayer Corps. According to the story's setting, to be promoted to Hashira, a member must meet one of the following conditions:

1. Successfully defeat any member of the Twelve Kizuki.
2. Accumulate the elimination of fifty or more demons.

These two conditions not only test a swordsman's strength but also their survival rate and experience in countless life-and-death battles.

Zenitsu's Astonishing Achievement: Single-Handedly Killing an Upper Rank Demon

In the final chapter, the "Infinity Castle Battle," Zenitsu Agatsuma reached the climax of his character arc. He faced alone his senior brother, Kaigaku, who had replaced Daki and Gyutaro and was newly promoted to "Upper Rank Six."

In this fateful confrontation, burdened by the painful past of his master's seppuku due to Kaigaku's betrayal, Zenitsu displayed unprecedented determination and rage. He was no longer the boy who needed to fall asleep to fight; in a fully conscious state, he executed his self-created "Thunder Breathing, Seventh Form: Honoikazuchi no Kami," delivering a strike beyond his limits and successfully single-handedly beheading Upper Rank Six, Kaigaku.

Without a doubt, by single-handedly defeating an Upper Rank of the Twelve Kizuki, Zenitsu Agatsuma fully met the conditions for promotion to Hashira. His strength at this point had undoubtedly reached Hashira level.
