A group of adults discuss a special child, gifted with intelligence but cursed with a skin disease that makes him unable to go outside, who they hope to find a cure for. The boy marks his spot in the book he is reading, going to return it to the shelf as Akaza appears to make his report, addressing the youth as Muzan-sama. The disguised Demon asks the Upper Moon if he has found what they discussed, to which Akaza replies that he has not, as he could not find any reliable information about the existence of the Blue Spider Lily.
The Upper Moon goes on to assure his leader that he will try his hardest to live up to his expectations, noting that he killed one of the Pillars as ordered. Muzan is unimpressed and proceeds to punish his subordinate, stating that he wishes the entirety of the Demon Hunters to be purged, something that Akaza failed to do when he left the three other Demon Hunters present with the Pillar alive. Muzan further expresses his disappoint in the Upper Moon for taking a blow from a swordsman who wasn't even a Pillar, and dismisses him. Akaza does as commanded, venting his frustration on Kamado Tanjirou's Nichirin Blade and promising to kill the youth the next time they meet.
Back at the Butterfly Estate, Zenitsu mulls over Tanjirou and Inosuke's sadness due to Kyoujurou Rengoku's death, bringing the former some buns to cheer him up. A distraught Kiyo accidentally bashes her head into Zenitsu's, crying out that Tanjirou is missing. An apologetic Kiyo further explains to the disoriented Zenitsu that Shinobu had gotten angry at Tanjirou for training while still injured and he had been instructed to rest. Remembering the extent of his friend's injuries, Zenitsu questions his intelligence.
Elsewhere, Tanjirou thanks Kyoujurou's crow for guiding him to the latter's home to fulfill his final wishes, noticing Senjurou Rengoku shortly thereafter. Addressing the surprised youth, Tanjirou asks him if he has heard about his brother's death, and tells him that he was given messages from his brother to relay to him and his father. Senjurou relates that he already knew about the former piece of information and asks Tanjirou if he is alright, as he looks pale. Before any further discussion can unfold, Rengoku Sr. angrily tells Tanjirou to stop, as he has come to tell them "useless crap". He goes on to say that Kyoujurou died because he became a swordsman without having any great talent, and that he was a pathetic fool of a son, to Tanjirou's astonishment.
