Saintess of the Abyss

Beneath a gothic cathedral an ancient demon lies sealed under the statue of the Virgin, and every saintess the church raises becomes its food. The last one, Bai Wei, was drained to an empty shell three years ago. Now a pink-haired novice has been chosen for the next ritual by the priest who brought her up. / But Su, a sharp-tongued investigator sent by the Holy See, has come to find out why believers keep vanishing. As the demon's lust spreads through the city, the priest must keep his secret buried until the ceremony.
