Lucky Cyan is a 21-year-old female human with cyan-colored hair and eyes, standing 170 centimeters tall. She was born on March 24 and is an Aries. She is the protagonist of the third story arc of the series, a supporting character in the fourth and eighth arcs, and a minor character in the remaining arcs. Raised in an orphanage after being the sole survivor of a plane crash, Lucky Cyan was exploited for her supernatural luck from a young age. People treated her as a good luck charm, using her to fulfill their wishes. Despite being celebrated as a symbol of fortune, she longed for a normal childhood with friends and the freedom to play. The pressure and isolation she felt eventually drove her to run away from the orphanage. During her escape, her only friend, a boy nicknamed Calamity (real name Luo), sacrificed himself to distract the orphanage director, allowing her to flee. She took Luo’s guitar with her, an instrument that emits green light when played and carries sentimental significance. After living on the streets, Lucky Cyan turned to street performance and eventually rose to become a singer-songwriter and a hero, ranking seventh in the hero ranking system. She is described as a singer-songwriter blessed with exceptional luck and a natural voice, overwhelmingly popular both as a hero and as a musician. Her motivations stem from a desire for self-determination and to escape exploitation. She seeks personal freedom and, later, to reconnect with her lost friend. Her key relationships include Luo, the orphanage director who sought to use her power for his own hero ambitions, and a brief connection to the hero Queen, who was the daughter of the journalist who found her after the crash. Over the course of her arc, Lucky Cyan develops from a passive child controlled by others’ expectations into a confident hero and idol who shapes her own identity. Her notable abilities include supernatural luck that influences events in her favor, though the exact mechanics are tied to her trust value, and her musical performances, which she uses to inspire trust and entertain the public. She also wields a guitar that appears to have special properties.
