I tried to upload Kira-kira Kaoru releases to some popular manga sites so more people would be able to enjoy this great story.
After a lot of registrations, so far only 2 sites replied to me :
Kira-kira Kaoru is now also available for download from Manga Traders and available for online reading from Manga Fox.
New releases will be uploaded there 7 days after release. So the first 7 days will be exclusively from those who download directly from Official Project Page : https://www.balamiere.com/manga/kirakirakaoru/
