An interesting detail I noticed about the Year 4 girl add-ons. Lobelia has prior connections to Fiona, Nanami has prior connections to Misaki and to a certain extent Nagisa. Even Elise, while not having any prior connections to any of the girls thus far, nevertheless was mentioned to have been a former Owner of one of the islands in the Venus Islands. Basically, all the newcomer girls for this year are tied to elements of the past. Something to ponder.
EDIT: Also, I noticed that Elise is the first girl to be released in July instead of August since Leifang. I wonder if that implies we'll be getting new girls quickly (the last time we got a girl in July, we ended up getting Fiona in a much faster rate than before).
