Star Guardian is a series of parallel universe skins in League of Legends that follow the story of a group of high school students who choose to become cosmic protectors and must battle cosmic enemies threatening the universe. However, they consequently learn of the anguish and perils associated with their newfound roles as self-doubt, desperation and the daily life of a high school student.

Much to the annoyance of her team, Jinx is an impulsive and sometimes cynical Star Guardian who loves a good, glittery explosion. However, when the fighting starts, Jinx will throw herself into the battle to protect others, especially her childhood friend Lux.
