>Speculation/Headcanon
I think Corbeau is based on Kazuo Taoka, I've been doing some reading.
>The Rust Syndicates crest looks quite close to the Yamaguchi-gumi.
>Yamaguchi-gumi are the ones who helped out with disaster relief
>Kazuo grew up as an orphan, a street fighter
>Took over the Yamaguchi-gumi from his mentor Noboru Yamaguchi
>Took over at 33
>Nicknamed 'the bear' because he clawed his enemies eyes
>Wary of other yakuza, didn't join the Kanto-kai

So, thoughts:
>Corbeau is his nickname
I wonder how he earned it, wonder what his actual name is.
>He's an honorable yakuza, so he follows the Ninkyo-do (pic related)
So he might not be submissive for sure, he could go either way but he will be a gentleman
>Rust Syndicate won't trust Team Rocket
>His age is 33
