You guys don't have FES, do you? At least, you don't read my posts.>"The Answer/Episode Aigis" as I've stated before.
You're stuck in the dorm in "The Answer", which is AFTER the main storyline and the MC is DEAD. You can't buy shit (or you can't at the beginning, at least), you're using Aigis and the difficulty is at least Normal, if not hard. You can't set the difficulty.
