Well i was try it from the beginning for the walkthrough but i lost my interest after i see the bugs.
Kyo is everywhere, massiv food drain at school to switch scene to get elisa. Energy drain for get in and leave the goverment, sisterhood or maid guild. Cant continue the quest for Olivia with her ring, because i dont get the sceen by the sisterhood....
and so on. Bug with sophie in the beginning, when you decide train you get points but you must eat too befor continue with school....
The different from the setting befor is that you get some things much faster then other things and you dont level sophie by killing enemys you use your stat points to increase her stats. Good master for Max HP, Knowledge for max mana, strenght for ATK power(how much damage the enemy lost by sucessfully hit) and knowledge for Eatk <- i have no idea for what that is.
Defence i didnt found anythink yet. Well that make a lot more sence because you have the feeling you are more connected with your servants. I dont know how to level Red at the cemetry.
Well in summary the game is not really playable. Only way i think is to use cheats. But you will get plotstopper like with Olivia and didnt continue more but iam sure there come more and more of them or in future.
