Good Cop, Bad Cop

Uzui and Tanjiro defeat an Upper Rank Demon.

An Upper Rank Demon has been defeated after a hundred years, disturbing Muzan Kibutsuji. A recovering Tanjiro discovers he has upset the swordsmith Haganezuka by chipping his sword and decides to head to the village where the swordsmiths live to talk.

Tanjiro encounters Mist Hashira Muichiro Tokito and Kotetsu, a boy from the village arguing over a "key." Tanjiro speaks on behalf of Kotetsu, but Muichiro refuses to listen. The key is used to operate a battle-type Mechanical Doll, Yoriichi Type Zero!

Yoriichi Type Zero is destroyed, but a sword from 300 years ago appears from inside. It is badly rusted, and Haganezuka appears, ready to perform a grueling whetting process handed down within his family line while demons inch closer to the village.
