Yue and Nodoka are practicing magic when they discover a spell called “The Red String of Fate.” Supposedly, the spell links a person with their destined partner. Nodoka decides to try it and soon finds herself bound to Negi by a red string. However, the string isn’t the mystical Red String of Fate, it is simply a magical red cord that connects two people and cannot be broken. Delightful. Meanwhile, Ayaka offers the class a complimentary trip to her family’s newly built spa resort. With the two of them tied together for at least a day, can Negi and Nodoka make the most of the free excursion without straying too far?
