Thanks again for the walkthrough. I'm playing the PS3 version and just got my Platinum Trophy
The only trouble I had was with the Mayuri and Moeka episodes since the mail list didn't show the mail for those episodes, even when I finished them. It also might be important to note in the guide that Episode 9 (The one you have to skip a message) is the one where you play as Moeka. (Abbreviated as 'Moe' in episode select) since you can choose between different episodes it might be important to note since I don't think it says the number of the episode in episode select unless I'm somehow missing that.
