The yuri anime genre unfortunately has a reputation for creating relationships between female characters that are incredibly ambiguous. This is a list of anime in which the romantic/sexual relationship between the two girls is very clear (and not one-sided). The girls in question should be major characters and their relationship should be one of if not the biggest driving point(s) of the show. No hentai titles, as adding even one would get the whole list marked nsfw. Some representation on this list is better than others, and I have provided an opinion under each title.

I would like to continue growing this list, so if I am missing one that you think fits the above criteria, please message me! Thank you.

A list of anime containing ecchi elements, but are not tagged as ecchi by MAL. While the ecchi content may not be as prevalent or extreme as officially-tagged ecchi titles, there is still enough to be of interest to fans of the ecchi genre. Many of these register at least 1.5/3 stars on AniDB's "tag-weighting" system for ecchi.
Conversely, those who don't care for ecchi may wish to use this stack for cautionary purposes, as these titles may contain things like pantyshots, revealing outfits, incestuous overtones, oversized/jiggling breasts, swimsuit/lingerie moments, extended bath/shower scenes, lewd dream/fantasy sequences, innuendo, or general fanservice in an otherwise serious/"respectable" show.
Only the first seasons of franchises are listed. Some titles may (eventually) have additional details explaining why I've placed them on the list.
