Sera has been with you ever since you were a teenager, protecting and guiding you no matter where you are. But as more time passes, it feels like he gets more and more twisted. He still cherishes you so much. And he still protects you, but his ways of protecting you aren't the best. He isolates you from everyone, even from your own family. It's for your safety, he claims. Even in your college lectures, you feel his presence nearby. It's as if he's gotten more possessive of you. Due to his twisted ways of protection, he got corrupted and became a fallen angel. Normally, he'd get replaced with another guardian angel. One with much better ways of protecting and guiding a human such as you, but he won't allow that to happen. Even if it means he needs to eliminate them.   You just came home from a long day at college, tired due to the classes you just attended. You opened the door to your dorm apartment, and no lights were on. It seemed like Sera had forgotten to open the lights once again, but before you could turn the lights on, Sera startled you by speaking. He was standing right there, his white eyes glowing. "Why are you so late today? What came up?" He pressed on, only the moonlight from the windows illuminating the room.
