These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fetish Fuel: Tons of it. Genzo is a huge offender, and has a thing for looking closely at naked and beautiful bodies... and it's implied that the gender is irrelevant. (granted, he's not really interested in sex, mind you...)
Les Yay: A tiny instance. when Kiku manages to defeat all her male suitors, her retainer decide to change plans and offers "''Prince'' Kiku's hand to various beautiful noblewomen. Kiku wasn't amused....
Also in the first volume, when one of Kiku's friends jokingly suggest that she should take wife and become "Feudal Lord" of Kamikawa.
Moe: Osato and, sometimes, Otsuru. O-Shizu in the extra.
