Yakuza 0 and the Kiwami games
Start with the rise of the Dragon of Dojima. Yakuza 0 explores Kiryu and Majima in 1980s Japan. Kiwami then remakes the first numbered story, beginning with Kiryu's release from prison, and Kiwami 2 brings a confrontation with the Dragon of Kansai. Together they establish the relationships that the later games revisit.
