You start to panic in fear after noticing the stranger, and recognizing him from the library. He, or she is probably some demonic being who came to take the TF-Note back, and steal your soul. Thinking of what to do, you grab his, or her hoodie, and launched him, or her against the wall near your window.
Luckily, the stranger didn't go through the window, but she definitely felt pain after you threw the person. The stranger lowered his, or her hood, and you discovered that under that hood was a girl with pink hair, and deer horns. "Why did you do that?" she asks. "Well, I thought you were going to eat my soul, once you had the book back," You answer. "That's ridiculous," she says. "I am a goddess after all." You place a pillow in front of you, as you sit with it in your lap when the goddess got closer.
