Demon Slayer: Kokushibo's Moon Breathing Technique, Explained

Key Takeaways

  • Kokushibo, Upper Rank 1 demon, wields Moon Breathing & blood demon art for deadly, unpredictable attacks.
  • Kokushibo combines swordsmanship with blood demon art to create a regenerating, flesh katana.
  • Master of Moon Breathing, Kokushibo’s techniques rival all but Muzan’s, making him a formidable force.

As a die-hard fan of the Dark Fantasy series, Demon Slayer, I can’t help but be utterly captivated by the enigmatic figure that is Kokushibo, Upper Rank 1 demon and brother of the legendary Yoriichi Tsugikuni. His life story, much like a Shakespearean tragedy, is one that spins tales of power, betrayal, and unwavering loyalty.


Kokushibo, the individual standing immediately below Muzan in rank and power, was formerly a human named Michikatsu Tsugikuni. He’s also the elder sibling of the renowned demon slayer, Yoriichi Tsugikuni, who was the swordsman that Muzan held in greatest esteem and fear.

Kokushibo employs a breathing method called Moon Breathing, which was originally developed as an expansion of the Sun Breathing technique. In contrast to Sun Breathing, Moon Breathing is dark and turbulent due to the incorporation of Kokushibo’s blood demon art. By merging Moon Breathing with his blood demon art, Kokushibo can release lethal assaults.

In his role as a high-ranking demon, Kokushibo exudes a tranquil yet lethal presence. Loyal to Muzan, Kokushibo boasts an exceptionally advanced level of Blood Demon Art. Before transforming into a demon, Kokushibo was an exceptionally skilled swordsman in his human form. After becoming a demon, not only did he acquire potent Blood Demon Art abilities, but he also significantly enhanced his swordsmanship skills through extensive training over nearly five centuries, reaching the level of strength he currently possesses.

As a devoted admirer, I find myself captivated by Kokushibo’s unique swordsmanship. Most of the techniques he mastered were self-taught, making it doubtful that they’d be passed down to future swordsmen. What sets him apart is his Blood Demon Art, which allows him to craft a katana from his own flesh. This gives him the ability to customize the blade’s length and even attach extensions. Remarkably, this katana can’t be damaged because it naturally regenerates, thanks to his Blood Demon Art.

As a gamer, let me tell you, taking down an opponent as weak as you would be like trying to beat an infant at a game. Once I’ve knocked you out, the remaining battles should be a piece of cake.

Kokushibo can generate potent, curved blades from his flesh katana, thanks to a blend of his swordsmanship and blood demon art. He controls the size, trajectory, and velocity of these blades, making his attacks erratic and tough for adversaries to anticipate. This unpredictability makes it challenging for opponents to counter his assaults, increasing the difficulty of defeating him. With each strike of his katana, Kokushibo produces crescent-shaped blades that are known to be infused with either yellow or blue energy, depending on the type of attack he’s using. Additionally, Kokushibo’s blood demon art and moon breathing technique enable him to lengthen or shorten the reach of his sword thrusts, allowing him to execute long-range or close combat attacks on his enemies.

Through employing the Moon Breathing method, Kokushibo possesses the ability to unleash sixteen lethal attack forms on his adversaries. Among these techniques are:

Kokushibo possesses an extraordinary ability to enhance his already potent moves when his flesh katana undergoes modification. For instance, he can unleash the Eight form: Moon-Dragon Ringtail, where he performs an immense, long-range slash that leaves a trail of crescent-shaped blades in its wake. The Tenth form: Drilling Slashes, Moon Through Bamboo Leaves enables him to generate three layers of spinning slashes, again adorned with numerous crescent cuts. Ultimately, his Sixteenth Form: Moonbow, Half Moon is his deadliest attack, allowing him to execute six curved slashes that slice through opponents who are several meters ahead of him. Unlike other blood demon art techniques, Kokushibo’s Moon Breathing technique outmatches all others except Muzan’s. The fusion of blood demon art and masterful swordsmanship is a formidable force to contend with.
