@SunnyShim Well you're not wrong that it's content dependant but my 50 chapter estiamte is for Manga that has an average of 30 pages per chapter which is about what it is for this one. Some mangas have chapters that are 15-20 pages and others that have 50-60 so in those cases obviusly the rule wont apply, also it depends on whether you count chapters with decimal places
(like 7.1 and 7.2 etc.) as individual chaptes or consider them a single one, a lot of manga will have 2 part chapters and each part is 30 or so pages. If you're gonna apply my esitamete to this then you'd have to count each part as it's own chapter.
Personally I've never seen a 12ep anime that covers only 20 chapters from the manga or as much as 110 so I think that's a bit exaggerated, maybe 35-80 would be more appropriet. Well if you can provide me with an exampe I'd be happy to eat my words on this.
@Cinsyac Yeah, from looking at the official website
(https://www.othersidepicnic.com/ ) it's pretty much certain that the anime will cover up to the ninja cat story, though I'm not sure if it will cover the last chapter of Vol.2 or not, It's not very lenghty but it may be a bit of a stretch. Well presonally I just wanna se Kozakura animated, she cute AF, also Toriko looks kinda wierd in the trailers.
