The world of Demon Slayer is filled with terrifying demons. However, none of them are as fearsome as the Upper Moons. This elite group of demons serves under the main antagonist of the series, Kibutsuji Muzan. Each of the Upper Moon demons is deadly and possesses their own set of skills, but they face threats from the Hashiras of the Demon Slayer Corps. Despite the Upper Moons being threatened by the Hashiras, there is one Upper Moon demon who can challenge them.
It is not Douma or Kokushibo, it is the Upper Moon Three, Akaza. He is the one who killed the Flame Hashira Kyojuro Rengoku. Akaza is immune to Nichiren blades like the Muzan. The combat skills of Akaza along with his stubborn nature and faster regeneration have made him invincible throughout the series.
Akaza’s advantage of regeneration and combat instinct
While Douma for his notorious ice-based Blood Demon Art and Kokushibo for his unparalleled sword skills, the Upper Moon Three, Akaza relies on his regeneration and endurance. His combat skills are top-notch to challenge any Hashira in one-to-one fights.
On the other hand, his regeneration capability from any injuries is godly. This makes him a formidable foe to Hashiras in the Demon Slayer. His regeneration allows him to ensure a prolonged battle against any of the Hashiras from the Demon Slayer Corps.
Akaza’s instinctive fighting style and capabilities of adaptation like Muzan allow him to remain undefeated till the very end of the series. While other Upper Moons heavily rely on their Blood Demon Art, Akaza’s strength lies in his physical strength and the strategic style of his battle.
The battle with Kyojuro Rengoku stands as a testament to Akaza’s strength
Battle with the Flame Hashira Kyojuro Rengoku is an evident moment of why Akaza has the same advantage as Muzan against the Hashira. In the Mugen Train Arc, fans remained overwhelmed by witnessing the strength of Akaza even after being hit by the Nichirin blade of Rengoku.
He almost fought with both Tanziro and Rengoku, and it took Rengoku’s life to sacrifice just to threaten the Upper Moon Three. Akaza pushing Rengoku to his limit demonstrates how immense combat ability he possesses. Not only that, but his will to outdo his opponents and stubborn nature make him appear as a great threat to the Hashiras.
This combination of rapid regeneration, immense physical strength, and extremely good combat skills allows him to have a similar advantage against the Hashiras in Demon Slayer leaving behind the rest of the Upper Moons.
These establish why Akaza is almost the same as Kibutsuji Muzan when it comes to being a great opponent to the Hashiras of the Demon Slayer Corps. No matter how powerful or fierce other Upper Moons may seem, the third rank holder, Akaza is that one demon who holds such exclusivity in terms of being a nightmare to the Hashiras.
