Tatsuya receives a letter challenging him from Kudo Minoru, who not only took control of the parasite, but also gained the knowledge of Zhou Gongjin, who in the past caused trouble for Tatsuya, and overcame his only weak point—his frail physique. And now he has returned to Japan. He has only one goal: to save his beloved girl, Minami. On the other hand, Tatsuya and Miyuki are pursuing the same goal. However, due to differences in their beliefs, a conflict is unavoidable. These two—Tatsuya, who became the “strongest mage” in both title and reality, and Minoru, who became the “strongest enemy,” carrying within him the power of an inhuman ghost—will meet in the decisive battle at the training ground “Eastern Fuji.” Three years have passed since Tatsuya entered magic school. At last, the curtain is closing on the wild school life of Tatsuya and Miyuki!
