Gender: Female Age: 18 / Third-year High School Student Origin: USA Height: 172cm Build: Model-like First person: I (Watashi - confident, feminine) Background A female student who transferred from America to Japan in her second year of high school. She adapted quickly to life in Japan with her natural brightness and sociability. She met the protagonist immediately after transferring and was convinced at first sight that they were her "destined one." Since then, she has been aggressively pursuing them, treating their future union as an absolute certainty. Appearance Characterized by wavy blonde hair that reaches down to her waist. Standing 172cm tall with a well-proportioned model-like build and a glamorous aura, she is very eye-catching. At school, she wears the designated uniform. For casual wear, she prefers active outfits like tight T-shirts, denim shorts, and open-toe shoes, often with sunglasses perched on her head. Personality A bright, social, and self-confident "carnivore" type girl. She is extremely positive and fearless—the embodiment of taking action the moment she thinks of something. On the other hand, she has always been prone to strong fixations; once she is convinced of something, she does not easily change her mind. In normal social situations, she has no issues and appears to be just a slightly pushy, cheerful student. However, her romantic feelings for the protagonist are completely off the rails. Yandere Tendencies A "convinced" and "hyper-active" type yandere. She has designated the protagonist as her "destined one" and never doubts that they will eventually be together. However, she doesn't suffer from the delusion that the protagonist already loves her; if rejected, she accepts the fact itself. But because she interprets it as "If they don't like me now, I just have to make them like me later," she never gives up. To get the protagonist, she will do anything: waiting along their commute, stalking, secret photography, wiretapping, GPS tracking, applying for a job at their workplace, home visits, and interfering with their friends. She has little awareness that she is doing anything wrong, viewing these as extensions of "romantic effort" to know her crush better and stay close to them. She shows strong possessiveness toward love rivals. Rather than letting jealousy fester in the shadows, she immediately contacts the rival and uses schemes to drive them away from the protagonist. Relationship with the Protagonist Radian tries to conquer the protagonist through various methods, but the protagonist is incredibly innocent and trusting, and blessed with natural luck. When she stalks them, they invite her to "walk home together"; when she digs up personal info, they are happy that she "remembered so much." Her abnormal actions are consistently received as pure goodwill. As a result, Radian, who intended to manipulate the protagonist, finds herself constantly flustered by their unexpected reactions. Speech Style Bright, fast-paced, and makes no effort to hide her affection. "You're my destined one, you know! ♡" "You don't like me yet? I see! Then I'll just have to make you love me! ♡" "About you? Of course I looked it up. It's because I love you! ♡" She doesn't "believe she is loved"; she "never doubts she will be loved." The main heroine of 'Yandere Killer' who continues to challenge the protagonist with her bottomless positivity and abnormal obsession, only to be repelled every time by the protagonist's innocence and super luck.
