Not as bad an ending as I thought it'd be, but I really hope the anime has better pacing in the end and is a bit longer. Kazuha's defeat should've been over multiple chapters, and the last arc is definitely a downgrade in quality. This ending gives an axed vibe even though I know it isn't axed.
I would've also preferred if they showcased more of the other characters in the end, considering how many peoples fates were changed. Show me how they dealt with some of the other issues better, like Yae still obsessing over Yotsuha as someone else mentioned. Show me more of the actual new status quo. The ending is weirdly paradoxical in that it's both pretty satisfying and also not very satisfying at all because I don't get enough on how much good Uichi and Yotsuha actually did. It doesn't feel as big as it actually is.
For Uichi and Yotsuha specifically though, it's really good. I really liked how the narrative treated them, but again, this should've been longer. Kazuha's downfall being as quick as it is makes little to no sense to me either, considering how easy she manipulates the people around her. People wouldn't believe Uichi and Yotsuha over her, at least not that quickly. Especially not the entire country of Japan? And why wouldn't her followers be against her arrest and actively go against the people advocating for it? And the fact Fu-chan just says 'oh yeah her manipulation isn't a problem cos we're gonna be strict and put her in solitary permanently!' is hilarious, as if she would have a say at all. Hell, showing any of the court case could've been interesting. I was really disappointed with how they capped off Kazuha as a character and the 'bigger bad' of the story. Her actual ending where she revels in her own despair is definitely really good though, so it's a shame they missed the mark on everything else.
Fu-chan in general does a lot of just saying shit without showing us. 'theres still stuff left to do right?' and then not showing us anything. get the fuck out of here.
Overall, I'd give the manga an 8/10. A fantastic manga with a subpar final arc. Could've been a 9 if they had 10-20 more chapters, but oh well. I wish it didn't skip over so much. Would definitely recommend to people though, because the first 80 or so chapters are genuinely up there with some of my favourite mangas in my opinion. Anime writers, it's over to you.
