Masato Kamioda is a devout Christian aspiring to become a priest. He is the only male student at the Saint Sophia Girl's Seminary as a part of the reform to repair the moral decline and the lax discipline at the academy.
Not everybody gives him a warm welcome as student body did not approve of admitting a male student. However, there are girls who welcome him, such as Ayano, and there are those who think he's a perfect boy-toy, such as Eri and Rumi. Can Masato stay at the academy without getting expelled despite the constant plot to have him to be expelled by Shizuka, the current student body vice-president?
