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.
YMMV: Kemeko Deluxe!
Fetish Fuel: Kemeko forces Izumi through a series of various clothing fetishes in episode seven... including rather disturbing ones.
Les Yay: Whenever Haya-chan is interacting with other girls (except Kemeko), especially Izumi. Ryoko, too, in the manga.
