Mack is an Afro-American Japanese who is travelling the world in search of the "perfect shot". He trains Kiryu to improve his running performance on the Kamurocho Hills site, and introduces Kiryu and later Akiyama to Revelations.

Yakuza 3 Edit

His encounter with Kiryu results in two things:

  • Chase training at the Kamurocho Hills construction site
  • Blogging as means to obtain Revelations

Yakuza 4 Edit

Akiyama encountered him at the rooftops of Kamurocho. Encountering him enables Akiyama to take certain photos at certain spots and obtain Revelation by e-mailing them to Mack.

Yakuza 5 Edit

Kiryu and Mack meet again in Nagasugai when Kiryu agrees to take over the rest of Mack's taxi ride in Wada's place. During the ride, Mack reminds Kiryu about Perfect Shots & Revelations which are then available afterwards.  Mack also sends emails to Saejima, Haruka, Akiyama and Shinada about sharing their Revelations on his website called MacSiv.
