Found a bug, does the dev read this forum? Spoilers ahead:
There's a variable marisa_anita_met and even though in my save Marisa and Anita have swum in a pool together and gone to the beach together, it is set to no. I noticed in Kara's "zero" story an if and the dialog inside didn't happen. A cursory look through the code shows the variable is not set until Anita's story 12 runs. And that make no sense.
