I have Outerworld Services turned on, and have posted a few messages during the various challenges (PR events, basically). The news updates on the menu screen indicate that challenges 1 & 2 have been completed, and that I should be able to find an NPC whose name is @LRFF13 in blue rather than the usual white, but I've seen no sign of this NPC.
Where can they be found? Do I have to be on at least a certain day? Do they appear only in New Game Plus?
