I think MC's name should be open to change. Also MC must meet all the three characters during the party or he will not understand why the tanuki is talking about people he doesn't know on the following day.

originally, I had it set in the demo that the MC talks to all four characters at the party in any order but we just couldn't get that to work in this build. since you can now only choose one & get the Rufus scene regardless after that. Maybe I can see about letting players change the MC's name. All four still do happen but the other two happen off screen.
