Guessing from the local manga guide pdfs wont work, but it looks like epubs should. I’ve never tried those though… It may only read the images from the epub, if there are any.
Ronin is a classic and Argo is another good one to check out.
Odd… What are the files formatted as? All of mine are cbz’s.
That’s odd that it won’t work with Tachiyomi for you. I followed the Kavita guide to connect it to Tachiyomi and it works fine for me.
+1 for Kavita, though I don’t use it for reading. I use OPDS in Kavita to read books on my phone (using MoonReader+ on Android) and share books with family.
There isn’t any English cast listed on behind the voice cast either, so probably just an error on the listing.
