The best way would be to see at home, in the affinity screen if you have unlocked all the images of each girl.
Yeah I've been using that but I've got no idea what I need to do for final level of librarian or swimmer. For the swimmer it might just be that I need to keep losing, for the librarian I have no idea. I've even force fed the angel a bunch of curses. Maybe I need a 2nd building from construction (I just have onsen) but I've maxed out the stuff there already. Oh and I am of course a max lvl librarian with max lvl int. (4)
If you read the losing event with "the swimmer" you will discover the way to win, you have to do one thing.
And with Beth, the librarian, there are two available dates that you can access by talking to her and picking the option, the dates are different depending on the day and you need to have the special dress!
Hmmm, I guess I'll poke around at the various timeslots and re-reading the swimming text should be easy. EDIT: Got the swimming win but still can't seem to take Beth on the date regardless of the time. I am wearing the dress and I've read all the books so not sure what I'm missing (still max int/librarian lvl)
If you have Beth at lvl 4 you need to study in the library to reach her lvl 5, if you have her at level 5 and own the special dress there should be a new option when [Talking] to her about a date, I hope this allows you to reach it.
If it doesn't I'll need more info because in the testing phase it worked.
If you mean the mystic dress we can buy from the shop in the mall? Certainly have that and lvl 5 Librarian. Talking to her doesn't seem to give me new options she just gives me the line about being busy. Doesn't matter the time of day or what my charm/might stats look like.
I suspect, at a guess, that I broke something by maxing out Librarian first but that's my only guess.
