No Matter How Many Lives - Demon Slayer S2 Episode 18 Reaction

Suzy you’re reactions are great but in this episode you missed a lot of information, Uzui is retiring so he won’t be fighting again, Kagaya said that Muzan was the sole blemish on his family, and a few points in the Gyutaro and Daki backstory

Well the good news is that season 3 has already been announced, although there is currently no news of the release date.

now we hopefully don't have 2 years before S3

fyi i think you missed it but he is retiring

So they never explained this in the episode for some reason, but the reason Ume stabbed the samurai was due to him trying to force himself on her as well as insulting gyutaro to her face. She only did it to protect herself as well as defend her brother.
