Demon Slayer Volume 21 primarily focuses on the conclusion of the intense battle against Kokushibo and the profound impact of this victory on the Demon Slayer Corps.
The Decisive Fall of Kokushibo
Volume 21 brings to a close the arduous fight against Kokushibo, who stands as the highest-ranking demon among Muzan's servants. This climactic confrontation sees the combined efforts of two formidable Hashira:
- Gyomei Himejima, the Stone Hashira.
- Sanemi Shinazugawa, the Wind Hashira.
Together, Himejima and Sanemi manage to defeat Kokushibo, ultimately sending this powerful Upper Rank One demon to hell.
The High Cost of Victory and Leadership's Burden
While Kokushibo's defeat marks a significant triumph, the Demon Slayer Corps pays an extremely high price for it. The victory is overshadowed by substantial losses endured by the organization.
In the aftermath of these devastating events, Kiriya Ubuyashiki, who has taken on the crucial role as the new leader of the Demon Slayers, faces immense challenges. He struggles significantly to cope with and recover from the severe casualties and the overall toll exacted on the corps.
