• Samurai Demon shouted at Scribe and fled into the darkness, warning the others not to come near him.

Scribe defeated the demons holding a group of geisha and learned that Warabihime had attacked Kyogoku House, where Nezuko and Koume were last seen fighting her. He began piecing together the whereabouts of Zenitsu and Tengen Uzui’s missing wives, then called the Dog-headed Demon over for information.

• The Samurai Demon fled, and Scribe silently killed the other demons, leaving the Ape Demon alive to plead for his life.
• The Ape Demon and Dog-headed Demon argued over who would be more useful to Scribe, while Scribe freed the captured geisha.
• A geisha from Hagimoto House told Scribe that Warabihime had revealed herself as a demon and slaughtered people at Kyogoku House.
• The geisha said Nezuko and the others had been suppressed by Warabihime when she last saw them, but she did not know what happened afterward.
• Scribe assessed the group’s likely whereabouts and wondered what had happened to Zenitsu and Tengen Uzui’s three missing wives.
• Scribe called the Dog-headed Demon over, hoping he could provide a clue.

Scribe learned that Dichai had ordered demons to capture people on a list, while Tengen Uzui rescued Hinatsuru from a demon’s trap. After hearing what happened, Tengen went to Kyogoku House to find Warabihime and protect those still there.

• Scribe questioned the Dog-headed Demon and learned that Dichai had a list of people to capture, including Hinatsuru and Agatsuma Zenitsu.
• Tengen Uzui found Hinatsuru bound in a pool of crimson liquid at Kirimise and rescued her when the liquid fled.
• Hinatsuru told Tengen that Warabihime had noticed her investigation and that the crimson liquid had captured her after she drank poison and pretended to take Warabihime’s medicine.

• Tengen arrived at Kyogoku House and was shocked by the tragic scene before him.

Tengen Uzui investigated the devastated Kyogoku House and chose to hunt the demons himself, while Scribe gathered survivors and searched the burning Yoshiwara Flower District. The two met after hearing a battle beneath the ground and prepared to investigate the vast hollow below.

• Tengen Uzui found the wreckage of Warabihime's room and concluded that Nezuko may have fought two demons, one of whom later protected her.
• Tengen Uzui found no sign that Koume or Nezuko had died and decided to search for the demons rather than meet Tanjiro and Inosuke or rescue his other wives.
• Scribe brought two groups of survivors together, killed the Dog-headed Demon when it tried to attack him, and led the survivors through the district.
• Scribe rescued people and killed demons as he crossed Yoshiwara, but noticed that several demons he had encountered earlier were missing and that the demons were less numerous than expected.
• Scribe met Tengen Uzui, exchanged information about the demons, and learned that a large hollow beneath them held the sounds of battle, though its entrance was too narrow to enter.

Scribe and Tengen Uzui uncovered a demon lair beneath the streets, while Inosuke found Tonryoku and other demons gathering around a blood pool and cocoons. Tonryoku sent Tengen Uzui’s missing wives, Suma and Makio, to attack Inosuke.

• Tengen Uzui used Sound Breathing: First Form to blast open a hole in the ground, and Scribe sensed a foul stench rising from below.
• Scribe and Tengen Uzui faced a group of demons pursuing people they had rescued, then rushed to deal with them.
• Inosuke smashed through the floor at Hagimoto House, squeezed through a narrow passage, and emerged in a cavern filled with a blood pool and red cocoons.
• Inosuke found Tonryoku, Mitsu, Rokuya, and other demons gathered around the cocoons, which were drawing from the blood pool.
• Tonryoku revealed Suma and Makio, who had emerged from cocoons with patterned bodies and lifeless eyes, and ordered them to attack Inosuke.

Inosuke fought Makio and Suma while Tonryoku’s group argued over Mitsu’s failed search for Koinatsu. As reinforcements broke into the demons’ hideout and a familiar human presence approached from above, the demons realized their position was in danger.

• Makio and Suma attacked Inosuke, and Tonryoku used blood threads to make them resume fighting after they paused at Tengen Uzui’s name.
• Rokuya taunted Mitsu for failing to capture Koinatsu, but Tonryoku ended their dispute and ordered them to focus on securing the hideout.
• Inosuke broke open Zenitsu’s red cocoon, but Zenitsu remained asleep in his arms.
• Tonryoku realized that several sounds came from attackers breaking through the stone, and Anze pointed out the wall where the digging was loudest.
• A burly figure, a woman emerging from a ribbon, and another attacker blasted open the hideout from different directions.
• Tonryoku sensed a familiar human approaching from above, and the demons wondered how Lord Dichai, Lord Imamura, and Lord Kamihito Ichi could have failed.

Tonryoku and the demons faced Shiragiku and Gyutaro, then Tanjiro and Nezuko arrived to join Inosuke and Zenitsu. Scribe and Tengen Uzui followed, and Uzui rushed toward his demon-controlled wives, Suma and Makio.

• Tonryoku slapped Rokuya and ordered the demons to stop panicking as Shiragiku and Gyutaro confronted them.
• Tonryoku realized Shiragiku and Gyutaro were demons with Upper Rank strength, while Mitsu recognized Gyutaro’s sickles and recoiled.

• Gyutaro glared at Nezuko, but Shiragiku stopped him and said they should wait for Scribe.
• Scribe and Tengen Uzui arrived, and Scribe’s sword aura struck the wall as the demons scattered.
• Scribe pointed out Suma and Makio to Tengen, who recognized his wives and charged toward them.

Scribe freed Suma and Makio from Dichai's technique and uncovered the blood pool's purpose. Tonryoku activated a final plan by feeding a concentrated mass of human blood to the pool, strengthening the demons inside the cocoons as battle approached.

• Scribe knocked out Suma and Makio with a controlled strike, and Sun Breathing purged the patterns from their bodies so they could recover.
• Scribe deduced that the blood pool could turn captured humans into beings between humans and demons, and Rokuya inadvertently confirmed his guess.
• Tonryoku ordered the final plan and tore out his heart to reveal a blood clot made from the blood of hundreds or thousands of people.
• Tonryoku threw the blood clot into the pool and leapt in, causing the cocoons to absorb blood and their occupants' auras to grow stronger.
• Scribe realized the cocoons contained demons and warned the others to prepare for battle.

Scribe realized the blood pool was awakening demons and turning them into Dichai’s backups, then stopped the others from reaching it. He had Gyutaro capture Mitsu alive and discovered that she could return to being human, though she still needed treatment.

• Scribe watched red cocoons hatch into demons, including three with Upper Rank-level strength, and saw a human transform into a demon as mission progress increased.
• Scribe ordered the others stopped from entering the blood pool, and Gyutaro attacked Mitsu while Rokuya kicked her aside and entered the pool with Anze, Shiragi, and Iryu.
• Gyutaro shattered Mitsu’s Blood Demon Art and broke her limbs, but followed Scribe’s order not to cut off her head.
• Scribe suspected Mitsu was still between human and demon, then struck her with his Nichirin Blade, causing her to expel strange blood and begin returning to an ordinary human state.
• Scribe realized Mitsu might be saved but noted that she needed treatment to keep from bleeding to death.

Nezuko revealed that Koume and Gyutaro were demons, while Scribe and the others faced an army of newly hatched demons. Scribe severed the Stone Demon's hand after it grabbed him, and two Upper Rank demons charged at him together.

• Nezuko told Tanjiro that the two demons were Koume and her brother, and Koume changed back to her familiar form.
• Koume pulled Gyutaro away, while Nezuko tended Mitsu's wounds and Scribe urged everyone to deal with the newly hatched demons.
• The demons targeted the humans, and the Stone Demon claimed Scribe as his meal before trapping him in its enormous hand.
• Scribe burned through the Stone Demon's grip and severed its right hand, sending the demon crashing into the others.
• The Cat-eared Octopus Demon and the long-nosed, elephant-faced demon agreed to attack Scribe together, and the Cat-eared Octopus Demon struck at his back.

Scribe and the Demon Slayers fought the demons in the cave while Gyutaro defended Scribe and Obanai Iguro joined the battle. The Hashira gained the upper hand, but Scribe remained focused on the blood pool, which had gone still after Tonryoku and the others entered it.

• Gyutaro stopped the Cat-eared Octopus Demon's attack on Scribe and fought alongside Tengen Uzui against the two Upper Rank demons.
• The Stone Demon ordered the remaining demons to attack Tanjiro and the others, while Nezuko joined the fight and Koume called out guidance to help them.
• The Stone Demon burrowed underground and tried to ambush Scribe, but Obanai Iguro appeared and struck him with Serpent Breathing: Third Form: Coil Choke.
• The Stone Demon recovered and attacked Obanai, who exploited gaps in his rocky armor and gained the advantage.
• Scribe assessed the battles and watched the blood pool grow calm after Tonryoku and the others had jumped into it.

Scribe broke the blood pool wall to stop Tonryoku from absorbing its nutrients, but Tonryoku consumed Anze and two other demons and emerged in a powerful new form. After Scribe tricked Tonryoku into revealing that his strength came from his own ability, the system warned that an unknown cause had changed the world's progression, and Black Feather arrived.

• Scribe attacked the blood pool until its wall broke and the blood drained out.
• Tonryoku absorbed Anze and the other two demons, then leaped from the pool in a transformed form.
• Scribe questioned Tonryoku and tricked him into revealing that his power-up came from his own ability, not the blood pool.
• The system told Scribe that an unknown cause had changed the world's progression and that he needed to investigate.
• Black Feather swooped down and landed on Scribe's shoulder.

Scribe learned that the Emperor’s people were approaching the Entertainment District and tried to end the battle before they arrived. Tonryoku self-destructed, and Scribe sheltered the others in a pit; the blast erupted into a towering pillar of fire as the arriving samurai watched.

• Black Feather told Scribe that people under the Emperor were heading toward the cave.
• Scribe warned Tanjiro and the others that the authorities had arrived, and Tengen Uzui and Obanai Iguro attacked the demons with renewed force.
• Tonryoku fled, then swelled with energy to self-destruct; Scribe chose to protect the others instead of pursuing him.
• Scribe beheaded the Stone Demon, the Cat-eared Octopus Demon, and the Elephant Trunk Demon, then dug a pit and placed the others inside before covering it with a fragment of rock.
• Tonryoku’s explosion engulfed the cave, and a pillar of fire rose into the sky as the survivors and arriving samurai watched.

Mr. Jing investigated the enormous crater while Mister Scribe and his companions escaped the ruins and rescued survivors. Mister Scribe later dug toward Tanjiro’s group and finally reached Tengen Uzui and Obanai.

• Mr. Jing ordered his warriors to search for survivors and dig beneath the crater, suspecting the explosion had originated underground.
