In the seventh episode of the TV anime ” Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train, ” the fierce battle between “Flame Pillar” Rengoku Kyojuro
Akaza has respect for the strong, even though they are demons, and enjoys the fight itself. Kyojuro was able to fight on equal terms with Akaza, but as a human, he has his limits. While Kyojuro’s damage was piling up, Akaza, a demon with incredible recovery abilities, was in top form.
Akaza was hit head-on by Kyojuro’s “Fire Breathing Secret Technique Ninth Form: Purgatory,” but instead inflicted a fatal wound with his “Destruction Killing: Annihilation Style.” In essence, “Destruction Killing: Annihilation Style” is nothing more than a bare-handed thrust, but when used by Akaza, who combines the physical abilities unique to a demon with refined martial arts, it is more than enough to take a human life.
Many viewers seemed shocked by the sight of Kyojuro’s torso being pierced by Akaza’s chop, with screams of “Rengoku-san…! Rengoku-san…!” “If you don’t like it, then stop!!!!” and “Aaaaaaaah…” erupting in screams.
