Demon Slayer Manga Chapter 66

Four months pass in a blur of training, recovery, and solitary missions. Demon Slayer Chapter 66 shows a Tanjiro who has grown noticeably sharper, clearing demon after demon on his own while Nezuko rests in her box. The grief over Rengoku has hardened into steady, purposeful discipline.

A letter from Senjuro arrives with research about the Hinokami Kagura, confirming it holds twelve forms, with hints of a hidden thirteenth. Tanjiro practices the dance until his body memorizes every step, chasing a technique his father performed while frail and sickly. Whatever the final form is, he intends to master it.
