Sooo having seen the first season, I've been pondering offering an AU thing with Hiroe (being a young lady of high station herself) as her lady-in-waiting and confidant since they're both very Mask Wearing, each in her own way. Could involve Shisui just knowing Hiroe's good at keeping secrets, or she could know Hiroe's secret as well somehow or other. I'm always open to other ideas, of course, if you've got another direction you'd be interested in taking it, tho I haven't managed to watch s2 yet so I'm not much use with anything from there... orz
