Kiryu's bucket list side quest in Like a Dragon: Infinite Wealth allows players to reminisce along with the Dragon of Dojima about his adventures throughout the series up to this point, giving this longtime protagonist the swan song he deserves. While players would expect the Memoirs of a Dragon that they uncover during this activity to include the highlights of Kiryu's adventures during the main series of games, some might be surprised to see references to games that were thought to be non-canon spin-off titles. The inclusion of these titles as references in Like a Dragon: Infinite Wealth is a nice nod, but it muddies the waters surrounding the series' canon.
