The Saintess's Dear Guardians

Lilia is an F-rank saintess, useless in the temple's eyes. She works hard to provide for her two guardians, but they cheat with her sister Seraphine. She decisively cut ties with them, and finds Kael, a corrupted slave nobody wants, as her new guardian. Unknowingly, her primordial breath awakens, and the Tablet of Life offers her three more mysterious guardians. Everyone mocks her, and Seraphine tries to frame her, but her power and guardians are much stronger than they can imagine.
