Well, I just googled it when I came home, and... well. (And the fandom isn't a lot better, also.)

Let just say that Kubo send his plot to hell, the man doesn't know what he is doing anymore. Tousen was a character with a build up that came from the end of soul society and was to pair with whathisname, the one who had a thing with Matsumoto. To end him like this, like a random non-recurrent villain who just appeared? Tell you, he doesn't have idea of what he is doing. (But to be fair, I don't know what happened to the rest of the characters, or if that goddamed arc already ended)
