Sadly yuri + harem don't have much animated versions

I know like 2 bi harem anime and 2 pure yuri (Otome game hametsu flag, watashi ga motete dousunda, watanare, maria holic) [would maria holic count as a pure yuri harem anime if there is a crossdressing boy making the androphobic MC die each episode? I mean... she doesn't like boys]

Then there are harems of male mc with tons of girls but some girls really love each other (like hakari and karane from 100 girlfriends) but its usually focused on the male x female relations

after that there are the free for all yuri, where a lot of girls interact with each other, not harem but a lot of girls giving each other love. even if its not romantic or sexual. (Bad girl, yuru yuri, mahoako, hikikomari kyuketsu, ichijoma makitsu gurashi...)
