@ilikepi31415 There are three more chapters in Volume 9 after this one. So then we'd have however many are in Volume 10 (which is already published), along with however many end up being in Volume 11. I assume Volume 11 will be the end.
So going by there being roughly 12 chapters per volume, I'd say somewhere around 25 or so chapters left to translate? That's obviously just a ballpark figure.
