I don't think they're ending next month or anything, but I don't see Neverland or Kimetsu lasting beyond 2020.
Did TPN sell more than Toriko?
No, not yet. Toriko had 20 million copies in circulation in June 2014 already, dunno how much it sold after that.
Muzan seems very unpopular. You guys that still read KnY think the villain is a weakness of the series? (I dropped it around the Love Pillar introduction)
I might not be the best person to answer, since I'm don't really like Kimetsu very much overall, but I would say so. It's not story-breaking, but he's just not very interesting and the series is suffering currently because of that, imo.
He's not terrible for a battle manga villain, but compared to many of the other villains in manga now, he's definitely a tad weak.
Muzan is very threatening, but I like villains which get development through the story. So far, the rest of the villains in KNY have had flashbacks that developed them, but Muzan's wasn't as well done as many others (particularly I like Akaza the best) so in my opinion Muzan pales in comparison to other villains in KNY and in other series.
He started as a great big villain, very intimidating and stuff but just ended up being a lot underwhelming, ofc because Gotouge wasn't able to make a better final battle with him, to be honest i think that this is the result of Gotouge rushing things for whatever reason, instead of developing the story more and making Tanjiro get stronger, he/she just rushed to the final arc with Muzan being way too strong for the current Tanjiro and cia and he/she had to find a way to make the Hashiras and Tanjiro be able to hold Muzan, which means, nerfing him.
MHA. Shigaraki got 6th, Toga 9th.
If you mean with known numbers just from the Oricon yearly charts, then yes. But atm Toriko does have 3 million more copies in circulation than Neverland
Depends a lot of what series you talking about because series like Naruto, Bleach, Toriko, Reborn and others had many really popular villains, Reborn used to have like half of the top 10 composed of villains (or ex-villains)
TPN is 18 Mil now.
That's more because almost of Reborn's cast outside of Tsuna's crew were antagonists (and Mukuro was as well).
Interesting take. I thought they would do well, but I checked some other polls and even some villains very popular in the West, like Aizen, did poorly on their series polls. I guess the love for villains is a western thing?
Or because they were just really popular with the fanbase? doesn't really matter if you have "so many villains" if they're not charismatic or popular with the fanbase, My Hero Academia only having Shigaraki or Toga appearing sometimes being a example.
