2096年4月到来，升入二年级的达也周围发生了许多变化。达也和美月转入了新设立的魔法工学科。幹比古从两个科目转到了一个科目。此外，达也和深雪开始与被派遣到四叶家当仆人的水波同住，三人的共同生活开始了。尽管达也希望今年能过上平静的学生生活，但新生包括七草家的双胞胎香澄和泉美，以及新生代表七宝琢磨，都是七草家的竞争对手，人人都各有特色，令人琢磨不透……。

第一高中进入社团招生周，招生过程风平浪静，风纪委员会的香澄却和社团联盟执行部的琢磨产生摩擦。另一方面，反魔法师的舆论逐渐高涨，幕后似乎有着七草家的影子…

恒星炉实验成功，参与实验的学生备受赞赏，琢磨却以为七草家藉此打响名号，和香澄吵到差点以魔法对打。为了解决这场纷争，学生会决定让七宝琢磨和七草双胞胎进行魔法比试。

九校战将近，第一高中也磨拳擦掌以连霸为目标，营运委员会却宣布更换三项竞赛项目，其中包括军事色彩强烈的「越野障碍赛跑」。九岛家前任当家「宗师」九岛烈这么指使的用意，是要进行「寄生人偶」的实战测试。

达也收到九校战相关的内部文件，得知九岛家要在越野障碍赛跑进行「P兵器」的实验，因而前往奈良的前第九研进行调查。 另一方面，掌握情报的四叶家，也联系101旅的佐伯旅长要求协助。

九校战正式开始，达也一边辅助选手们拿下佳绩，一边还要忙于调查比赛背后的阴谋。就在达也终于得到线索准备外出时，深雪却一脸愁容挡住他的去路。

越野障碍赛跑比赛当天，达也预先来到赛场要除掉所有寄生人偶。借由八云先前的指点，达也顺利逐一封印人偶内部的寄生物，在最后对上最强的四具个体「Prime Four」。

The Nine Schools Competition has ended, and it is now the second semester. Ayako and Fumiya visit Tatsuya to deliver a letter they were entrusted directly from Maya. The letter was a request asking for Tatsuya's cooperation in capturing Gongjin Zhou. The Kurobas were also pursuing him but lost sight of him in the Kyoto area. It seems Gongjin Zhou has been receiving help from the Traditionalists, a faction of Ancient Magicians, in his escape. The Traditionalists and the Kudou Family have been in conflict with each other for many years. So, Tatsuya decides to reach out to Fujibayashi, Retsu Kudou's granddaughter, to ask for Retsu's cooperation in capturing Gongjin Zhou.
