Demon Slayer: Kimetsu no Yaiba Swordsmith Village Arc

To explain to Hotaru Haganezuk, the master swordsmith who forged Tanjiro's sword, why his sword was so severely injured, Tanjiro had to travel to a swordsmith village. And at that time the enemy drew near Tanjiro as he awaited the swordsmith to fix his sword... ... On the other hand, Muichiro Tokito, the Mist Hashira, is engaged in a violent struggle with the demon, but things do not seem good and the conflict is escalating. Tanjiro and Genya, another demon slayer, are needed to assist him. Fighting two upper-rank demons at once would be bad enough. Moreover, each of these two demons can split into four new bodies, each of which has the ability to regenerate almost instantaneously. Would Tanjiro and the others be able to beat such a foe?
