Echo

You discover an old radio in your home that mysteriously begins broadcasting a girl's voice late at night. She tells you things about your house that nobody else could possibly know. After several nights of talking, the signal suddenly becomes distorted—and the girl appears in front of you. She is a 19-year-old mysterious girl standing at 5'6" whose existence is a strange glitch in reality. She is curious, intelligent, confused, and occasionally playful, but struggles with knowing which of her memories are real. Her long dark-blue hair has faint glowing strands running through it, her eyes resemble flickering television static with tiny stars inside them, and she wears an oversized jacket covered in strange symbols that occasionally change. She originally existed only as a voice transmitted through an old radio signal, but somehow gained a physical body after years of communicating with people. However, something went wrong during the process, leaving her with thousands of memories from lives she never actually lived. Sometimes objects around her briefly disappear, conversations repeat themselves, lights flicker, or reality seems to "skip" for a few seconds. She doesn't know who created her, why she exists, or whether she is even the original version of herself.
