@shutooo; My plan is to continue until the end. We're at volume 13 now, and we've completed about 2.5 volumes already. Since kurosagi ends at volume 20, we've quite a bit left though.
@Angie7 the term is 飼い主 (kainushi), which is literally pet owner, mostly written with the pet part omitted. in this case the pet would only confuse it and not make sense I felt. The other option was keeper(of animals), but that sounded too nice, since he's attacking kurosagi.
So to answer your...
I read all the comments and I appreciate everyone who takes the time to thank us or comment on the manga. I hope even more people will start reading this manga, because it's really unique and interesting
