Kawaii: (
↗kawaii (
可愛い) = "cute" or "adorable") If you've watched anime in Japanese, you've heard characters use the term 'kawaii'. So if the title makes you want to say that (often using
↗chibi characters, i. e. small and super-deformed), then it fits.
Harem: (
Story/Location) This is a sub-genre of the "
Romantic Comedy" genre. To qualify you have to have a single, dateless, nice guy who suddenly finds himself surrounded by a bunch of hot girls/women who are interested or attracted to him to varying degrees. The male lead may also live with many of these girls.
Yuri: (
Objectionable Content) (
↗yuri (
百合) = "lily", indicating "female homosexual love") These are titles that show intense emotional connection, romantic love or physical desire between women. Yuri is not a genre confined by the gender or age of the audience, but by the
perception of the audience. In short, yuri is any story with women (or girls) in love (or lust) with other women (or girls). (This definition is an edited version of
the one that
Yuricon provides; see also:
↗Wikipedia:Yuri)
