Kyojuro Rengoku vs Hairo was a battle that took place in a city within Tōkyō, Japan. It focuses on the battle between Kinoe-ranked Demon Slayer Kyojuro Rengoku against Lower Rank Two Hairo.

Prologue
Kyojuro, Mitsuri Kanroji and a squadron of Demon Slayers are called to arrive at Tōkyō to find the whereabouts of a possible member of the Twelve Kizuki. He orders the squadron to split in a group of 2, with Mitsuri and Kyojuro heading alone.

Battle
A piece of dynamite is shown inside a nearby chapel and goes off, creating an enormous explosion. This greatly confuses Kyojuro, Mitsuri and other Demon Slayers. Mitsuri exclaims that she wants to be some help to Kyojuro and sprints towards the location of the explosion to help any nearby civilians. Before going far, a bullet nearly scraps off her face from the top of a nearby building. Kyojuro looks at the trajectory of the bullet along where the bullet landed and sees the source, an individual sniping on the very top of a building. The individual is shown as a man with a western suit with a black cape-like cloak wielding a M1903 Springfield sniper rifle. The man exclaims in frustration that he didn't get to kill Kyojuro's "subordinate" and tries to calm himself down as he reloads his rifle. He goes for another shot but sees that Kyojuro has disappeared from the frame. Suddenly, the Kinoe-ranked Slayer appears in front of him and uses the Flame Breathing, First Form: Unknowing Fire to try to behead the man but he dodges the attack with only his right arm holding his sniper rifle being cut off. The man calms himself down saying that everything he has done was for this day. He speaks Kyojuro's surname, repeating that everything is for this moment. Kyojuro sees the kanji for Lower and Two on his left iris proving that the man is a member of the Twelve Kizuki.

The Lower Rank tells Kyojuro that he never forgot the shame he felt, and that he swore that he was going to kill him. Kyojuro responds, asking him who he is, the Lower Ranked is stunned, asking if he forgot who he was, but Kyojuro exclaims that he never met him before-hand. Enraged, the Demon shoots himself in his mouth to regain his composure. A large explosion happens behind the Demon Slayer as the Lower Rank announces that he has set up explosives around Tōkyō.

Suddenly a barrage of bullets travel towards the Demon Slayer which blocks all of them. The Lower rank is shown emerging Springfields, Mauser C96's, and a Webley Revolveron his right hand, and unleashes a barrage of bullets, which Kyojuro evades. He takes cover behind a nearby billboard and wonders how to counter against the firearms, but the Lower Rank manifests his Blood Demon Art shadows under Kyojuro which emerges multiple Mauser Model 1893's and Berthier rifles and fires them towards Kyojuro, while the Demon Slayer destroys them an the billboard by using the Flame Breathing, Fourth Form: Blooming Flame Undulation. This shocks the Lower Rank as he fires another bullet with a Gewehr 1888, which manages to graze Kyojuro's left cheek-bone. He then delivers a swift blow to the Lower Ranks' neck but to no avail as his skin appears incredibly dark with multiple eyes with concentric ripples covering their entire eyeballs. This completely negates the attack and prevents Kyojuro from escaping with his Nichirin Sword. After taunting him, the Demon releases a ton of dynamite sticks onto the nearby floor, blowing himself up along with the entire top-half of the building.

Mitsuri heads toward the building, but the Lower Rank quickly gets behind her and regenerates, proceeding to slam her down to the ground by pulling one of her braids of hair. He begins to tell her that Kyojuro is still alive, and that he will suffer extreme pain. He boasts that torturing was his specialty as a human, and continues to taunt and chastise Mitsuri. But suddenly, Kyojuro appears and uses Flame Breathing, Fifth Form: Flame Tiger and stops the Lower Rank from attacking Mitsuri, he delivers a slice to hiss neck, and knocks him back. Kyojuro proclaims that he is a Demon Slayer, and that he will do his duties. Kyojuro orders Mitsuri and the rest of the Demon Slayers to disarm the explosives around Tōkyō. Kyojuro wonders as to why the Lower Rank is fixated on him, but he affirms that he will still defeat him. The Demon scoffs at his announcement, and tells him that a gun is unbeatable to a sword, and that Demons are always stronger than the Demon Slayer Corps. Kyojuro remembers his mother's motivating words about his family.
