This chapter was pretty depressing. Even if Kokushibou brought it all himself, its sad to see how he wasted both his life, his happiness and his legacy due the envy and grudge he felt for his brother, combined with a series of bad choices through his long life. Even if he was very unsympathethic, Gotouge somehow managed to make me pity him, and seeing how he regretted all his decissions as he dies for good, while not having anyone comforting him in his travel to the afterlife (have in mind that even Douma of all people had Shinobu telling him farewell before he died) only made this the more sad.
I really liked Kokushibou. He had a cool (if creepy) design, had an awesome fight (one of the best from the manga), needed four strong oponents to be taken down, and his backstory was pretty solid. Again, he was worthy of having the title of Upper Moon 1, and I think he's one of the best villains of the manga.
Other than that, I have clear that Yoriichi is basically Japanese Jesus. I really want to see how the fight where he almost killed Muzan went.
