[Closed]From which chapter of the manga does the anime pick up from ?

The problem is you can't really answer this question in an easy way, because the anime skipped a bunch of chapters in-between S1 and S2, and also many episodes weren't adapted in the same order as the manga since they had very little relevance to the story

The first season covers up to chapter 48 I believe. Then the OVAs covers some chapters haphazardly, including the important Trouble Quest arc which is chapters 93-98. Then the very first episode of Motto covers both a story from chapter 49 (right after S1 ended) and one from chapters 87-88 in the same episode for example. So really it's pretty hard to say where to start if you're insisting on switching from manga to anime part-way through

I guess if I was to recommend anything then I would personally say read from the beginning up to chapter 92, then watch the OVAs, then proceed with Motto and on into Darkness. It's probably closest to what you're looking for

And no, you should not skip the OVAs if you do that, or at the very least don't skip OVA 4/5/6 because those are pretty important to the future story since they introduce new characters and stuff
Hope that helped somewhat
