Reijuu no Acolyte Lufia

A story about a pure-hearted elf girl who struggles to stay strong despite being defiled by worldly desires. The orphaned elf girl Lufia is taken in by the church. Outwardly, she serves as an acolyte of the church; behind the scenes, she provides services in return for donations. Under the false pretense of "offering herself to god," Lufia is trained to serve as comfort for so-called benefactors. Day by day, she bravely fulfills her duties with her own body. Leane, a senpai who has long served the church, is a half dark elf and half human. Though she was initially harsh toward Lufia when they first met, her compassion for Lufia's situation eventually wins out, and she begins to look after her. Day after day, the two of them carry on their service, answering the church's demands. Before long, word of the "elf servants" spreads, bringing in many benefactors. The days of bearing countless desires upon their bodies continue with no end in sight...
