The Storm of Zeuan

The ambition of the magician family led them to awaken things that should not be awakened in order to obtain stronger power, and the destruction of the world is imminent. Only the strongest magician Princess Suobu Ye Feng (dubbed by Miyuki Zecheng) can prevent this from happening. However, Ye Feng, who was plotted by his subordinate Zamon Suobu (dubbed by Oyama Rikiya), was trapped on an uninhabited island that was enchanted. The sister of Fuwa Aika (voiced by Hanazawa Kana), a good friend of high school sophomore Takigawa Yoshino (voiced by Onki Uchiyama) (voiced by Toyoyuki Toyonaga), was killed by a burglar, but Mahiro believed that his sister's death was suspicious. In order to investigate the cause of his sister's death, Zhenhiro reached a secret deal with Suobe Yefeng through the floating doll on the sea. A month after Mahiro disappeared, he suddenly fell from the sky on a snowy winter day accompanied by butterflies all over the sky. At the same time, the terrible "black iron disease" spread throughout Japan. What kind of contract did Mahiro make with the magician princess, and what mission did he come to this world with?
