i think its not easy to buy the English book yet and its release but all i know is that you need to go to the official website of the published magazine and also all i know is the fact that you will need to go to the original site of the japanese book for finder. i forgot the original site and most of them are not released yet. but in japan its already released even the finale for the manga itself.
Thanks a lot mate!
I bought some of mine through barnes and noble and some through right stuf anime which is now crunchyroll. I have up to volume 12, which is the latest release as far as I know.
Thanks a lot for providing info about platform to purchase
