Kyojuro Rengoku vs Hairo

Kojuro 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 Tokyo to find the whereabouts of Hairo. 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.

Hairo 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 Moon is stunned, asking if he forgot who he was, but the Slayer exclaims that he never met him before-hand. Stressed, Hairo shoots himself to regain his composure. More bombs explode as he announces that he has set up explosives around Tokyo.

Hairo generates an artillery of fire-arms, and unleashes a barrage of bullets, which Kyojuro evades. He hides behind a wall, but Hairo generates more rifles and aims it at the Slayer. Kyojuro proceeds to cut the wall behind him, with Flame Breathing: Fourth Form - Blooming Flame Undulation, Hairo aims his rifle but the bullet grazes the Flame User. Kyojuro lands a hit on the Moon's neck, but he taunts him, and deploys sticks of dynamites around him, blowing up his surroundings.
