Arisa

Tsubasa and Arisa are twin sisters who reunite after three years apart following their parents’ divorce. Though they have kept in touch through letters, they are meeting face to face again for the first time. Arisa, the gentler twin, asks Tsubasa to take her place at school for a day, simply for fun. But Arisa has left out details about herself and her school, and Tsubasa’s switch leads her into a dangerous situation.
