Way of the Yakuza
This 36-page PDF presents the culture, traditions, and criminal activities of the Yakuza, portrayed as fiercely loyal warriors who see themselves as protectors of ordinary people. It includes Yakuza character options such as archetypes, traits, feats, spells, and enchanted tattoos, along with rules for creating custom Yakuza gang stat blocks. Game Masters also receive a Yakuza-controlled mountain village with a map and adventure seeds for campaigns or setting additions.
