Ahaha, Orion can get in the way. I understand. If you already know spoilers, there’s a yandere guy as well in Amnesia. And yes, Hakuoki is indeed good.
My favorite otome game is Nameless, developed by Cheritz (you know, Mystic Messenger). Gorgeous art, intriguing story. It requires you to play all routes to know the truth, though, and there’s psychotic guy again that looks nice outside, some messed up backstory, and rather dark bad endings. If you agree with that and about jointed dolls becoming real, you can go ahead and play it, I recommend it. Dandelion, Cheritz’ previous game, is said to be good as well, but I haven’t played it as it has skill points etc I’m too lazy to play. It is said that the antagonist in Nameless exists in Dandelion as well.
I’m currently playing Nightshade which is about ninja and has plenty of action. The heroine is great as well. I have only played one route, but I love it.
If you want a normal one, though, I think Storm Lover Kai is good. It’s a PSP game, though. It doesn’t have much story other than “girl meets boys, choose one, unravel their problems”, but I think it’s pretty cute and funny (especially “baka couple” scene).
Collar x Malice English is coming, and they said it’s good, so let’s wait. And maybe wait for a better translation of Taisho Alice, it seems good.
Also, have you play Hatoful Boyfriend? (laughs) It’s good for a breather, I think.
I guess that’s all. You might want to try Ozmafia, but honestly, I don’t really like it. I’ve never played Toki Meki Memorial Girl’s Side, but I really want to…
