So I have mainly been reading on SJ app and its been going fine and i have been enjoying the series. That being said I recently brought the physical volumes and some of the chapters inside them are VASTLY different from the ones available digitally. Like for example Saitama actually meets up with Child emperor in the physical volume after his fight with Phoenix man whereas in the digital they never meet and Saitama just fights orochi. Other differences being Mask's fight with that BDSM girl etc. Also Garou is a absolute beast.
