Tensei Seijo to Shinkan wa Mada Ai wo Shiranai

Canary has worked her entire life as a lowly servant in a mansion, but when the national aptitude test is held, she's decreed to become a saintess. Memories of her past life, where she died as an overworked virgin, come flooding into her mind. Canary believes her luck is finally on her side, but soon discovers the truth behind the saintess's power to store mana, transferring it through carnal desires of the flesh?! And her partner is a handsome, seemingly perfect instructor priest, Eagle. Who could've known a temple is used for such craven desires?! Tentacles, monsters, and a world you just can't seem to hate (with a little hint of sensuality), this isekai love story awaits! (Source: MangaPlaza)
