Just an observation.
I have the Kodansha Comics English volumes 1 - 3 and looked here to continue reading.
KC have chapter breaks (but not numbered - wtf???) and, on comparing the online vs printed versions, the chapter breaks are completely out of sync.
Presumably the online chapters are from the monthly comics so have arbitrary chapter breaks. Maybe KC changed things to make for a better flow.
Anyways, Vol 3 gets us up to the end of online chapter 38.
