Top 5? Uff...my memory for names is bad and i only played week 1 so far...
1. Mika and Rikka are my absolute favorites
2. Kaede
3. Panini erm Kotori
4.
Middle Daughter (i named her Saya, dont remember the original name...it was a hard fight between her and Kotori, but my taste won in the end...i prefer goth ^^)
5.
Little Daughter (i named her Sayo, dont remember the original name...why 5? Well, she needs a little overhaul...she makes such a silly face while kissing and i'm not into SM, so i think she will even lose this place once Month 1 is complete and Lains next Mod is ready)
I dont like Akis personality so far, maybe it get better after week 1, but as long as she stays like this there is no chance for her to get near my top 5.
Michiko is a borderline...exhibitionism is ok and she also likes girls, thats a huge +, but i dont know her enough to be sure she isnt a slut.
I also need more time to verify Shina...for now she got place 6 in my ranks.
That are all the girls i remember for now...well, at least for my top list
