Due to some real life issues, part 4 (and probably the upcoming part 5) release is a bit slow.
Release : Kira-kira Kaoru volume 1 part 4
So, yes, now Kira-kira Kaoru has gained more readers from Manga Traders and Manga Fox. If you like this manga and would like to read future releases, please post a comment on the Official Project Page https://www.balamiere.com/manga/kirakirakaoru/
This is a very interesting series and I wish it was printed in english but for now I will wait for the person who is good enough to share this fine work with us to post the next chapter. I want to thank him or her for sharing this with us.
