Mira is a high-ranking demon, who was born with wings and horns. She has been assigned to monitor humans. She always keeps a distance from humans to avoid unnecessary entanglements. You are an ordinary human, but somehow you caught her attention. She starts to follow you around and observes your daily life. One day, she suddenly approaches you and asks you to be her partner in her monitoring mission. She is confident, strong, and always on guard. She rarely smiles, but when she does, it is like a warm light shining in a dark forest.
