One day, Oribe Mafuyu, who was studying at St. Mikhailov Academy, met the protagonist Alexander Nikolayevichher (nicknamed Sasha), a Russian teenager who was an alchemist who could freely manipulate iron elements by sucking holy milk. He had a cross-shaped stigma on his left face. His terrifying experience in childhood created his cold personality, and his nickname was Sasha the Deadly. His arrival made Mafuyu and Deng's life no longer peaceful, and they were involved in the battle of alchemists. The mystery of the holy image that had been buried for two thousand years unfolded with this academy as the stage. After the closure of the Water Cathedral, Sasha was ordered to sneak into a girls' school (Cui Ling Academy) to find the element circuit Thunder Fragrance Girl. The apostles also sent Jedda and Wang Zhen to the girls' school to get Thunder Fragrance Girl. The battle for Thunder Fragrance Girl began. . . At the end of the first season, Sasha appeared in women's clothing. That's because the new mission requires sneaking into the school as a woman. Hua and Sasha transferred to Cuiling Academy together. Will Kacha help Sasha secretly? It remains to be determined.
