Important note: This article contains spoilers pertaining to the Demon Slayer manga series.

Kokushibo's background in Demon Slayer

Before his transformation into the infamous demon Kokushibo, he bore the name Michikatsu Tsugikuni. Michikatsu was the older twin brother of Yoriichi Tsugikuni, a renowned figure in the series' universe celebrated for his unparalleled talents and the creation of the Sun Breathing technique. Michikatsu's transformation into a demon was rooted in his profound feelings of inadequacy and jealousy directed towards his younger brother, Yoriichi.

While Michikatsu himself possessed impressive swordsmanship skills, he perpetually found himself in the shadows of Yoriichi's innate abilities and natural brilliance. This envy reached its peak when he witnessed Yoriichi age gracefully, even after awakening the mark of a demon slayer, a mark commonly believed to limit an individual's lifespan to a mere 25 years. This mark symbolized immense power, but at the expense of a shortened life. Nevertheless, Yoriichi defied this fate, further amplifying Michikatsu's sense of inferiority.

One of Michikatsu's primary fears was the notion of perishing at a young age, specifically when he reached 25, due to the curse bestowed upon him through the mark of the demon slayer. This apprehension, paired with his longing for Yoriichi's extended lifespan and exceptional abilities, compelled Michikatsu to actively seek an avenue for evading this seemingly unavoidable destiny. This quest ultimately brought him face to face with Muzan Kibutsuji, the original and most formidable demon.

By transforming into a demon, Michikatsu aimed to not only hone his swordsmanship skills but also evade the dreaded curse of the demon slayer mark and its inherent untimely demise. As Kokushibo, the name he assumed as a demon, he ascended to the prestigious position of Upper-Rank One within the Twelve Kizuki, outranking all but Muzan in terms of sheer power.

The final battle against four Demon Slayers

Kokushibo faced a daunting challenge as he came face to face with four powerful Demon Slayers: Muichiro Tokito, Genya Shinazugawa, Sanemi Shinazugawa, and Gyomei Himejima. The final assault of the Demon Slayer Corps on Muzan and the Kizuki was in full swing.

The conflict arose when Kokushibo and Muichiro Tokito were brought together in the same room within the Infinity Castle. Demonstrating his exceptional skills, Kokushibo successfully severed Muichiro's arm. Despite this setback, Muichiro impressively managed to stop the bleeding. Kokushibo, wanting to intensify the conflict, then impaled Muichiro with his own sword.

With Muichiro in a dire situation, Kokushibo presented him with the option to join Muzan as a loyal demon. Before Muichiro could make a decision, Genya interrupted by firing his firearm. Kokushibo swiftly evaded the gunshot, but not without severely injuring Genya by severing his arms and torso. Right when Kokushibo was about to deliver a final blow to Genya, Sanemi, Genya's brother, stepped in.

The battle between Sanemi and Kokushibo turned into a fierce confrontation. With his extensive expertise, Kokushibo initially had the advantage. However, the tide of the battle shifted dramatically when Gyomei Himejima, the Rock Hashira, arrived. Gyomei, renowned for his extraordinary physical strength, presented a formidable challenge to Kokushibo. Their clash intensified, and in a stunning twist, Gyomei unveiled his secret weapon, the Demon Slayer Mark, which he had saved for his ultimate battle against Muzan.

During the intense battle, Sanemi and Gyomei demonstrated impressive teamwork, delivering powerful strikes to Kokushibo. However, the formidable Upper-Rank One demon proved to be a formidable opponent. Utilizing his extraordinary blade, capable of extending and transforming, Kokushibo successfully wounded both Sanemi and Gyomei.

In a surprising turn of events, Muichiro disregarded his injuries and rejoined the fight, providing crucial assistance to his fellow Hashira. The collective efforts of the Demon Slayers began to overwhelm Kokushibo. Gyomei, wielding his flail, shattered Kokushibo's head, while Genya, utilizing his unique bloodthirsty power, restrained the demon. Muichiro, with his blade now crimson with determination, set his sights on Kokushibo's vital organs.

However, in a desperate attempt, Kokushibo unleashed a barrage of blades from his body, causing severe injuries to Muichiro and Genya and also hurting Sanemi and Gyomei. Despite this, the Demon Slayers pressed on. Genya, utilizing another Blood Power, managed to anchor another tree into Kokushibo’s back, further restraining him. Gyomei and Sanemi continued their assault, with Muichiro delivering a critical blow that rendered Kokushibo immobile.

In his final moments, Kokushibo reminisced about his past encounter with his younger brother, Yoriichi. Overwhelmed with remorse and deep self-reflection, Kokushibo questioned the life choices he had made and the path he had taken. Collapsing to the ground, he came to the realization that his desire was not to become a monster, but rather to emulate Yoriichi. Marking a poignant conclusion to the battle, Kokushibo's last thoughts centered around his brother, leaving behind nothing but his shattered flute.

Conclusion

In conclusion, Kokushibo's character in Demon Slayer illustrates the intricate nature of human emotions and the extreme measures that can be taken because of envy and ambition. His transformation from an ambitious human to one of the most formidable demons highlights the series' exploration of the blurred boundaries between good and evil. Ultimately, his defeat at the hands of the Demon Slayers serves as a powerful reminder of the collective strength that can be found in unity and unwavering determination.
