While the episode focuses largely on the initial revival of Senku and Taiju, the production of paper is a symbolic milestone. It represents the transition from a "survival" phase to a "record-keeping" phase, allowing Senku to document his formulas and plan the 2,000,000-year leap back to modern technology.
However, for archivists, fans in regions without legal access, or those who want to own a DRM-free copy of the episode they love, the URANiME release represents the pinnacle of what fan preservation can achieve. Dr Stone E01 WEB x264-URANiME
