I read it on manga piracy sites, more than one because they'll have different titles faster, sometimes better formats in one over the other, and any one could get taken down at any moment. try a few manga sites first before totally dismissing them, they often have lots of customizable options. Although obviously physical is usually better, but often way more expensive and potentially much slower. Piracy is the only way I get the newest chapters of Jojolion the minute someone scanlates them, for example.
