I am definitely a dedicated Luna fan =D
I think Luna is the best written character in whole game. From there it can be seen as I have a crush on Luna but her reactions are priceless, her sadness and happiness is like really getting me sad or happy =D Her backstory is magnificient. I nearly cried at the "My name is Luna" quest
I dont care there isnt any sex scenes, she is crown jewel of porn games =D
About other girls I think Gracie is a bit scary and in a way nearly non-human, even Cordia says "It is not the danger you would be that worries me, it is the danger you would become" she is intended to be like that way but still a bit scary -especially scary in the scene of "The Blizzard Princess" quest where Gracie says to MC "I will hurt you"-. Isabel is teasing too much without giving a relief and she is married so going after her is a moral dilemma at some point.
