Theory 1/example
Based on how Sabitsuki never leaves her room unless she accesses her computer, she may be known as a shut in. some of the NPCs she accouters may be some of the only friends she is able to have or access. Hating reality, she goes onto her computer and tries to escape responsibilities in her life. In the School, she gets chased by the Red Demons at a certain point. This could mean she was bullied or even harassed. While you see countless demons trying to get her while she runs, this could mean she is a target in her school. Knowing how Smile never seems to be a nuisance by trying to kill her in anyway, could be a friend to her as well as some of the other NPCs. However, you see Smile the most around the dream world, possibly for support. Another example is how she can get possible revenge on a certain NPC Kaibutsu. How she tries to stand up to him when you select the Pipe effect. When you try to hit it, it automatically turns around and kills Sabi.
