Plot
Set in modern-day Japan, the plot centers on Tsubasa Uehara and Arisa Sonoda, twin sisters separated by their parents' divorce who keep in contact through letters. Finally meeting again as teenagers three years later, tomboyish Tsubasa is envious, but proud, of her popular sister, in comparison to her own school life where she is often referred to as the "Demon Princess." When Arisa receives a letter from her school denouncing her as a traitor, she attempts suicide and becomes comatose. Shocked and saddened, Tsubasa poses as her, attending her school to find out why she tried to kill herself. She learns that Arisa's class sends wishes on their cellphones to a person called King each Friday. The King only grants one wish weekly, resulting mostly in violence. Tsubasa resolves to stop the King and find out the person's identity to save Arisa, in the hopes of waking her from her coma.
