Azurite terms of address?

[Katuko]

And I'm the one who told you about the title. As they say on the Straight Dope MB, "ignorance fought".

BTW, I remember where I first heard the title: reading Shogun

I learned the meaning of shogun from video games, but I'd never encountered daimyo before so I didn't think it would be a title rather than a name. Thanks for enlightening me, I always like learning new stuff. :P

Speaking of family, is Kubota his given name or his family name? Or perhaps it is both, as he is the current head of family anyways? I must admit I know little about how this works in other cultures.
