I literally don't have enough for words for how awesome this movie is
Spoilers ahead!!
I watched the movie already knowing Rengoku was gonna died (due to someone spoiling it to me) but regardless I still cried. Demon slayer is the only anime that has EVER made me cry when I am not even attached to a character, it was really hard to hold back tears and when i did cry, I quickly regained myself but was back to square one. There's something about this anime that is just so emotional, the speeches Rengoku gives, their expressions not even My hero or Attack on Titan can evoke this feelings out of me.
Truly, the best anime of this century.
