Tanjiro Kamado, Nezuko Kamado, Genya Shinazugawa and Mitsuri Kanroji vs Hantengu

Tanjiro Kamado, Nezuko Kamado, Genya Shinazugawa and Mitsuri Kanroji vs Hantengu is a battle that takes place in the Swordsmith Village, between Demon Slayers Tanjiro Kamado and Genya Shinazugawa, Love Hashira Mitsuri Kanroji, and Demon Nezuko Kamado against Upper Rank Four, Hantengu.

Prologue
Muichiro pinches the bridge of Tanjiro's nose to wake him up, asking him if he knew Kanamori, Muichiro's new swordsmith. Tanjiro says he did know the swordsmith, guessing he was with Haganezuka. After a bit of conversation between Tanjiro and Muichiro, Upper Moon 4 shows up. The narrator remarking that his skill at staying hidden was shocking, neither Tanjiro or Muichiro knowing it was a demon until they saw it. Though, they could confirm it was an Upper Rank Demon even without it having a number in his eye.

Battle
In the span of a blink of an eye, Tanjiro and Muichiro assume their battle stances at the Demon. Muichiro attempts to behead the Upper Rank by using the Mist Breathing, Fourth Form: Shifting Flow Slash. Hantengu easily dodges the attack by leaping onto the ceiling still screeching from fear, begging the Demon Slayers to stop jumping him. Tanjiro informs himself that Hantengu is not innocent at all as since he is an Upper Rank, he has consumed a plethora of innocent people in order to increase his power. Tanjiro unsheathes his temporary Nichirin Blade that Haganezuka forged due to him leaving the Swordsmith Village before the latter can finish polishing the ancient blade. Tanjiro then uses the Hinokami Kagura: Sunflower Thrust in order to pin the Upper Rank so Muichiro can behead him but Hantengu dodges again. Tanjiro is heavily confused as to why the Demon isn't retaliating towards them back. Nezuko then comes and hits Hantengu with a rising front kick as she is turning into her demonic form, but Tanjiro tells her to not turn into one as he believes that she'll attack the swordsmiths herself. Muichiro then beheads Hantengu quickly and easily, which shocks the other two.

Tanjiro quickly questions if there is a special condition that it isn't as simple as just decapitating. He shouts at Muichiro to not let his guard down, while Hantengu regenerates from his head and body creating two different bodies. He also shouts that he'll take the one in the back, Muichiro attacks one of the new bodies and they gush him far out the battlefield with one of his fans. Nezuko grabs hold on the rubble of the building keeping her and Tanjiro from flying out of the battlefield, with Tanjiro shouting Muichiro's name in horror. The two Demon Slayers then witness two demons, one wielding a Khakkhara/Shakujō and another with a fan shaped like a Japanese maple leaf.

Even while Aizetsu continues to belittle Genya, the latter chants the Japanese Amida Sutra When in Śrāvastī! In the lonely gardens of Jetavanavihāra.

Aftermath
Tanjiro "sacrifices" Nezuko by exposing her to sunlight in order to behead Hantengu, however Nezuko had survived the sunlight without a scar on her. It was said by Tamayo that Nezuko may be able to survive in sunlight in a matter of time.
