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.
Unfortunate Implications: For a series set firmly on the yuri side of things, it is deeply, unpleasantly homophobic. I mean, really, let's take a long, honest look at the implications and outright textual statements in play: Adult lesbians are sexual predators who will throw intelligence and responsible moral conduct to the winds if there's the possibility of having sex with young girls, which leads to: Lesbians in a position of power will abuse that power for the sake of corrupting young girls into being soft, passive sex objects. Lesbian teachers are in it solely so they can corrupt and seduce their students. The lesbian agenda is to sideline men and take away the women. Women who aren't sexual predators cannot effectively resist, and in any case, women cannot rape women, because a properly passive young woman will eventually accept and enjoy unwanted sexual contact, until it ruins men for her. Therefore, homosexuality is a learned behavior akin to The Virus, and should be resisted.
