However the rules for this Nine Schools Competition are different from previous years. One month before the Nine Schools Competition, significant changes in the rules and events were made which forced each of the national magic high schools to be busy up until the day of the competition. While Tatsuya is planning for the next Nine Schools Competition, an anonymous message is delivered. The message contains information that a new plot will occur during the Nine Schools Competition. While the competition is happening, Tatsuya runs through the dark forests of Fuji, in order to oppose the conspiracy of betrayal. The 2nd Year of the Nine Schools Competition has begun.
