If you watch anime superficially that's your problem
In this scene Uika literally says that Saki has become oblivion because she wants to forget. Oblivion is her main issue, she screamed back at mygo that she wanted to forget everything
Oblivion concerns many topics. The fear of losing control, the fear of moving on, the fear of letting go of people and things that are dear to you, the problems of growing up and the problems of responsibility
Every girl has own fears, just because you don't see them doesn't mean they don't exist or they don't make sense. It's just you don't understand them or don't even try to understand them
