The members of the magic academy enjoy mixed results while training with their knight school counterparts. With the demonoid threat looming over them, Shin decides to hold a magic training camp for the group over summer vacation.

As Shin's training camp continues, the group members' skills improve. Aug's fiancée and younger sister ask to come stay at the camp, and their presence compels Shin and Sizilien to come to terms with their feelings for each other.

Before Sizilien will allow Shin to date her, she insists on having him ask her parents for their blessing. Shin experiments with a new form of magic, and thinks the Ultimate Magic Study Group is ready to take their training to a higher level.
