1 Kazuki, manager of Stardust says "You know how it is with the Chairman" regarding Fuma Oyabun when first meeting Kazuma in Yakuza 1. This could mean the death of Sera or that Fuma is busy now he is interim Chairman. Unclear.
2 In the period after Fuma's shooting, some of the Tojo Clan are calling Nishiki the chairman, but this is not confirmed as Kiryu is called the 4th.
