Sorry, the next chapter will be out June 28th.
On April 28th Finder Volume 11 was published, which contains all the chapters up until now, plus the pudding extra.
There was also one small extra with Asami's birthday. But nothing containing the plot.
So it's June 28th when the plot will continue. When something will show up here, no one can tell. The scanlators don't upload their work here themselves.
And Sensei just embarked on a new arc, which would go completely into Finder Volume 12 (maybe even 13... 14). I don't see an end coming very soon with two new characters introduced, Asami's backstory coming up, we having to find out what happened with Akihito, and what Sakazaki, Sudou and possibly Aaron are up to, not to mention that she is obviously taking Mikhail and Fei Long further.
I'd say: There's still a loooooong run coming for us. YEAH!
Ok so I did a bit more research and I believe that the next chapter was released on April 28. However, it won’t be translated right away, as we already know since it’s May. I also think that the Finder Series is coming to an end soon, but that’s just my hope. I read somewhere that someone thinks its Finder is NOT even close to ending. As to where I got this info... on chapter 89, the last page gives a website, https://www.b-boy.jp/ special/finder/ , and this has all the info I just listed. You will have to translate it though. Hope that helps(⌒▽⌒)
