Hiiro no Kakera, Amnesia Recommendations
The female protagonists have a slightly flaky characterization to them in both otome game adaptions, but each seek out some kind of mystery regarding their past. There's also a darker side to the entire plot for each series.
Must point out the similarities in these, even though the storylines are really different. Also, one takes place in an urban city surroundings and the other in a rural japanese village. But as a reverse-harem fan I enjoyed these both. A female main lead is introduced into a confusing new situation where different good-looking guys will start appearing around her, and things that she does are of extreme importance for her whole world or reality, of course along with the company of the guys.
The main character is a girl, who doesn't know what happens around her and there are some pretty boys, which protects her.
It's similar because they are both super natural, romances with bunch of guys and one really important girl, in both stories the girl are th main characters, I recommend this because I have seen some amnesia and a little bit of hiiro no kakera
P.s ( the theme song in both is awesome!!!^^)
