In Yakuza 6, a guy called Nagumo speaks with a dialect. Just an example of one line from him is
"今度こそ白黒つけちゃるけえの"
which, in regular japanese, I'm assuming is
"今度こそ白黒つけてやるからな"
Anyways, he keeps using "けえ" at the end of sentences (I'm assuming it's a dialect version of "から"). What region is this dialect from? I have a feeling it's a Kyuushuu dialect, but I wanted to confirm.
