Shinobu Kochō notes that Tanjirō is on trial, for which Kyōjurō sees no need for as he was protecting a Demon, which is a clear violation of conduct, he states that it was matter they could deal with themselves.

### Mugen Train Arc

Kyōjurō is sent to ride the infinity train after a number of Demon Slayers who where sent there to investigate it fell silent.

As he sits on the train, waiting for for to take off and devouring his eleventh bento bog while shouting "Tasty", Tanjirō, who'd heard that he was going to be there and consequently followed him along with Inosuke Hashibira, Zenitsu Agatsuma and Nezuko in order to ask him about the Hinokami Kagura, comes up behind Kyōjurō. After the Hashira finishes his food and Tanjiro explains his question, Kyōjurō energetically answers that he doesn't know what the Hinokami Kagura is and that this is his first time hearing about it. He says that he's delighted that Tanjirō applied his father's dance to his fighting style, then swiftly changes the subject and tells Tanjirō that he should become his Tsuguko. Tanjirō tells him to slow down and ask if he can at least try and help a little more to answer his question.

Kyojuro says that Flame Flame Breathing has a long story, and says that there has always been a Hashira in evey age who uses Water Breathing and one who uses Flame Breathing. He explains that the other Breathing Styles were derived from either those two or Wind Breathing, Sone or Thunder. Kyojuro then asks Tanjiro what color his Nirichin Blade is, to which latter responds that it's black, and KYojuro laughs out and says that that must be unfortunate. Tanjiro asks why that is, and, as the train starts to take off, Lyojuro explains that he's simply never seen a swordsman with a black blace become a Hashira before, and that he's heard people whose blades turn black don't even know which Breathing Style to master. Seeing Tanjro's face, he tells him not to worry and that he'll train him up back at his house.

Inosuke sticks his head out the train's window, and Zenitsu tells him to get back inside beacuse it's dangerous for him, and Kyojuro agrees, since he doesn't know when the Demon is going to appear. Zenitsu shocked by this, and Kyojuro explains the situation and he disappearances of the Demon Slayers sent investigate the train. Zenitsu starts screaming that he wants to get off the train.

The conductor then comes over to the four of them to stamp their tickets. Tanjiro smells something bad, and Kyojuro appears to sense it too as he asks the conductor to step aside as he draws his sword. A large Demon appears at the other end of the carriage, and Kyojuro asks it if it was hiding its Blood Demon Arts as he found it hard to notice it's presence, before darting forward to behead it with his **Flame Breathing: First Form - Unknowing Fire**. The Demon's body falls to the floor, and Tanjiro, Inosuke and Zenitsu all crowd Kyojuro, praising his swordsmanship and pestering him to let them become his disciple. The Hashira enthusiastically agrees and says that he'll look after all of them.

Sometime later, when the four are all asleep, Kyojuro dreams thart he's back at his house, telling his father, Shinjuro, about his promotion to Hashira. Shinjuro dismisses him, saying it's pointless and doesn't matter because neither Kyojuro or himself will ever become great people anyway. Kyojuro gets up and walks out of the house, out into the garden, his little borther, Senjuro coming to gree him and asking if their father was happy about the news and wondering if he would acknowledge him too if he also becomes a Hashira. Kyojuro remembers how his father used to be, a happy man who was passionate about training his children as swordsmen, and how he changed after their mother's death.

He admits to his brother that Shinjuro wasn't happy to hear the news, but enthusiastically adds that Kyojuro's passion won't dire because of that and that he'll never be disheartened. Senjuro's not like him because he has an older to look out for him. He reassures him that whatever path he takes, he'll be a wonderful person, and; as Kyojuro hugs his brother, he tells him to do his best and keep on living no matter what.

Still within the dream, Kyojuro begins to tutor Senjuro in his sword skills. In reality, a young girl, who's working for Enmu, ties her wrist to his uncounscious body with a special piece of rope that was made by the sleep Demon, allowing her to enter Kyojuro's dream. Enmu has sent her in to destroy Kyojuro's spiritual core, which, when destroyed, would render him a lifeless shell unable to put up a fight against the Demon. The spiritual core lies in the area of uncounsciouness just outside of Kyojuro's dream realm, and she quickly slips past him and Senjuro whithout him noticing. She finds his unconsciousness, which lies past the wall surrounding his garden, and breaks into it, finding herself in an unsually hit and flame-covered unconscious area.

The girl locates his spiritual core, but, as she goes to break it, in reality, Kyojuro grabs her by the neck and lifts her off the floor, causing the version off her inside his dream to fall still because he is suffering stress in the real world. Kyojuro does this on instinct because he would be unable to fight if she destroyed his spiritual core, and is therefores unable to cause her any more harl because ha has no reason to kill another human. Kyojuro and the girl are stuck in a deadlock, both unable to move.
