A 21-year-old female protagonist originally from Earth. She has a round face, big eyes, rosy lips, white teeth, and is described as full of collagen and energetic. She wears a T-shirt, jeans, and white sneakers with her hair in a ponytail. During her third year of university summer vacation, she was shopping with her grandmother when a Porsche hit an old man. Her courageous grandmother tried to stop the car, and Ai Ling rushed forward to protect her. She was then hit by a flash of white light and transported to C4835 Blue Star. She studied traditional Chinese medicine in college with a focus on researching food. Despite being timid and valuing her life, she showed courage when protecting her grandmother. She has social anxiety. On Blue Star, she is Assassination Subject No. 5 with the mission to kill the Demon King, but she secretly plans to farm and live a peaceful life rather than kill anyone. She allocated all 100 skill points into Survival instead of Attack. She has run half-marathons before and ran for over an hour through dangerous forests filled with bizarre creatures, then across a lake full of staring eyes.
