Following their parents' divorce three years ago, Tsubasa Uehara and Arisa Sonoda, identical twins, were forced to communicate solely through secret letters. Eager to reunite, they arrange a meet up at their beloved childhood park. At school, Tsubasa, known as the "Demon Princess," struggles to get along with her peers while Arisa thrives as the perfect class representative with top grades and an abundance of friends. Arisa suggests that Tsubasa take her place at school to experience her life. Although Tsubasa welcomes the opportunity, she remains envious of Arisa's perfect life. When Arisa discovers Tsubasa's feelings, she makes a suicide attempt in front of her. Determined to uncover the truth behind her sister's pain, Tsubasa takes on Arisa's identity and attends "King Time" for the very first time. During this weekly Friday class, one student's wish is randomly granted. Initially, Tsubasa dismisses it as a harmless joke until someone gets hurt, and the "King" proves their ruthless determination to grant any request. As Tsubasa delves into the mystery of the "King's" identity, she uncovers startling revelations about her sister.
