I never liked when yukkuris referred to themselves or their things as beautiful or cute unless they're referring to their children (and even that can get excessive at times). It just seems so pretentious and egotistic.
City-sect Alice is sort of a canon-wide accepted Alice quirk, but I never really noticed "cute Reimu," and going back it does seem to be used more for Reimu.
Also, round hereabouts Marisa's penipeni is braggable.
