"About that Yoshiro guy: according to Mayuri, he has honor just in name. He must be a cutthroat he acchieved his position due to blind luck, guile or violence. I trust he can be easily threatened, I just don't think any decision he makes may be kept afterwards. Honor works both ways, and if he is not bound by it, then he may just free her and then order her to be shot in a week. Still, it's a possibility, and we should not discard.
Madame Kikuya should be a little bit different - she was a geisha once, and she is not one anymore since she is old, that's all. She envies Mayuri, and can't understand why she wants to break free: but the thing is, sentimentalism is what makes her decide for keeping her in geisha life, and that's something we can - with the proper arguments - change. Look, she was an entertainer, and she longs for her former life... it does not seem that difficult to confort her dreams and remember her who she is... to gain her sympathy, and then use her own world-view to convince her the best thing for both of them was to let Mayuri leave. I guess I can talk her into it - probably for free, just basing my arguments on Japanese Traditional Aesthetics - but if that's not possible, then maybe we can make a deal; something like that: Mayuri truly respect Kikuya, the geisha way of life and the Aikiwa house: maybe she can honor them all better in a different way, maybe she could write a essay or a biography of the legendary geisha Kikuya, who afterwards became a standart on preserving the tradional arts of geishahood. That kind of thing."
Fractal tone of voice clearly shows that he is over-excited, and is not hiding it.
