I used to watch a lot, i mean, almost every otome games adaptation anime a few years ago :"D but i stopped around before the covid hit, because i didnt watch anime anymore and basically just got no time sadly.. BUT my all time favorite is UTAPRI! love the first and second season

i even memorize the OP and ED still getting giddy with the song, i woud sing a long like it was a concert, so much memoryy. and i dont know why but to me, Brocon anime adaptation is good(??) like, they have so much characters but can give them bits of scene, even just a little haha, but cute.
And personally, i dont really enjoy Hiiro no Kakera, not because the anime is bad, but because when otome anime usually focused on no-one route, HnK is focused on the main boy.. and i prefer the other guy

and it hurts me seeing the MC not being with my fav, eventhough i love the song so much (Fujita Maiko is goddess i swear) but the anime is good, just personal preference
And ofc the legend Hakuoki series, no words can describe my love for that game.. and watching the anime just making me bawling my eyes T.T so good yet so painful to watch..
Amnesia is nice too! Arcana Famiglia is also cute, makes me want to play the game at that time <3
