ever since I've read in Bakuman about Eiiji pulling a speechless chapter on Crow, I searched for but couldn't find other manga that don't contain any speeches - either in one or multiple chapters or in the whole work
Are there any? This can't be just recently from Naruto #599 and Fairy Tail #299, can it?
Gon. All of the volumes do not have any dialogue at all.
Try it, one of my must-read manga list.
There is a whole section for that on Mangaupdates:
Best Manga Chapter for me. Hunter x Hunter 339.
Journey to the End of the World is one that has only a narrator, but no text and conversation, I wonder if that counts as well?
