There are a few updates to my list:
1) OVER REQUIEMZ by Otomate — I don't like the art style all that much, but its tags, the possibility of an evil route, and the whole Tengoku Strugglesque kind of mix are much more pleasing to me.
2) Les Grandes Odalisques: Réveil by Lateral — I was really happy to find out that the project hasn't been abandoned after all; the rights were acquired by its scenario writer, Kano Takako!
3) Hakuouki Ibun: Berezinskii no Majo by Otomate — I was lured in by the Slavic-sounding names and the whole Slavic vibe. My native language is one of the Slavic ones (and I was born in a city that's actually pretty close to the river the title is named after, which makes the whole thing even more amusing to me), so I have a huge soft spot for anything Slavic that pops up in Japanese media. I genuinely enjoy it whether it's super stereotypical or a little more subtle and nuanced. I'm a huge fan of cultural mixing and cross-cultural influences, and it's always fun and fascinating to see how people from outside the cultures imagine and portray others. Even the weird or hilariously inaccurate stuff is interesting to me because I love picking apart where those impressions come from and how they get turned into characters, settings, and tropes in mass media. The funniest thing to me is that they actually squeezed it into the Hakuoki line, which is otherwise so unapologetically Japanese historical fantasy, and their European setting seems to be this wonderfully bizarre mix of Eastern European influences, with Hungarian (including some very Dracula-coded names), German and French names thrown into the mix XD
