Got around to cracking open Yakuza 7 (Like a Dragon). Yakuza's often toyed with having multiple protagonists, but also a slight awkwardness about having to have Kiryu playable in every game. In LAD, I think they addressed this really well by having Ichiban team up with a bunch of party members so that he doesn't have to carry the entire story by himself.
In fact, powerwise he _can't_ carry the game by himself because he's not a monster like Majima, Saejima, or Akiyama! (Though I do miss being able to wander anywhere in the city without having to worry about party wipes.)
My favorite so far is Adachi, an old ex-cop who lets it all hang out. The scene of him laughing his ass off at Ichiban's haircut was perfect. He also has the coolest jacket.
