I thought that when the fang used "we" he was talking about the teamwork with the other bodyguards to keep him in peak condition, not that he was touched in the head.

Also a bit of trivia: the sixth ward of The Inside is called Rikuko, meaning "six GU". A peculiar choice for the name, consider other wards use dragon, tiger, wolf, bear, etc.
@Renard
I originally thought it meant he ascribed a different him to every one of his forms, but now I guess he just feels like the soul of everyone involved with that Gu thing is part of him.
I don't like how Gensai went from a strong fighter to another plot armored character, i get it for Ohma since he's the protagonist but Gensai just takes on the Fang as if he was nothing.

There's nothing plot armory about the Beard. Plot armor is asspulling shit to keep someone in the game even when they're outmatched. Beard, on the contrary, has been consistently portrayed as the ultimate in mastery of pure martial arts. He doesn't really have any flashy techniques, he just turned his fingers into rebar through sheer training. Where his adversaries use limit breaks and special techniques, he just blocks, dodges by a hair, counterattacks. He's pure, distilled Karate. He's a simple fighter, just incredibly tough to surprise and overcome. None of his strengths come out of thin air to help him win, unlike Agito who's literally nothing but that.
