Screw it, I give up.
I'm on Day 20. I've got Fame in the 700s and naughty level in the 1000s, along with a Level in the 30s, all available quests and side-quests completed, and the best equipment.
I can't figure out how to get Fyllia to walk around naked at will.
I can't figure out how to get any reaction from that avatar-having girl in the Slums other than "..."
I can't figure out how to reach that chest in the middle of the moving-path hallway in the demon lord's castle.
I can't figure out how to get into the basement dungeon of the demon lord's castle.
I can't figure out how to unlock these last four H scenes in the reminiscence gallery, and I've tried talking to everyone with different outfits.
*sigh* I wish this game had a guide... Or was in English... -_-
