The phrase refers to the availability, often unauthorized, of a Japanese comic series about a quartet of powerful warriors connected to a cataclysmic prophecy for no cost. It commonly indicates avenues where individuals seek to access digital scans or downloads of the serialized publication without paying the standard purchase price set by authorized distributors.
The desire to access the series without payment stems from multiple factors, including financial constraints, the appeal of immediate gratification, or the geographic unavailability of officially licensed copies. Historically, the digital distribution of copyrighted material has been a contentious issue, balancing copyright protection with consumer demand for affordable access.
