Avalon's is pretty great too. If I don't get either of those story chapters done before the deadline, I'll probably grab hers. I liked Nito's as well, but no way am I gonna get LB7 clear before the exchange period ends.
I did "most" of Ooku when it first released, but didn't finish the main story. I've had the permanent version unlocked for a while now, and I was hoping it saved my progress from the original run, but nope, it's making me start at the beginning. Is Heian Kyo the one where we get the 2nd plugsuit mystic code (the other one with the character swap skill)? I know we get a Kintoki costume, but I can't remember which one gives the Mystic Code. I'd like to get that sooner than later.
I haven't checked those yet, but for 100 SQ, I might throw my hat in at them.
