Akaza has to go down as one of the best characters of all time, I don't think I have seen so much depth in a character in a long while, and it's not just his backstory too, it's all the details in his design, all the details in his personality contrasting with rengoku, but similar to rengoku too when he was hakuji, the way he stands like his master, the way he talks asking for peoples names, which I think is a callback to keizo asking his name, he has amazing depth if you try to find it
