There's Definitely Something Wrong with My Plant Spirit Cards

[Yuri, reverse harem] She transmigrated into a nun and died right from the start. Luckily, she was revived by a [Plant Spirit Card]. The bad news was that this card was seriously messed up and turned Flora into a vampire who would die in sunlight! Staring at the bizarrely illustrated card glowing with an eerie pink light in her hand, Flora fell into deep thought: This card is trying to kill me! Even more absurdly, despite being a vampire, she was chosen as the church's saintess?! If her identity was exposed, she'd get the full-service treatment at the stake! Fanatical believers, a watchful bishop, suspicious higher-ups: this was a hellish start. Flora gripped the card that seemed more and more like a trap and decided to struggle to survive. She would play the role of a holy, pure saintess while secretly studying this thing that kept producing strange prompts, hoping to stay alive. She thought she could just barely keep things going with her acting skills and the abilities the card provided, but then everything went completely off the rails. The noble and beautiful pope came by late at night with "specially made holy water"; the tsundere demon girl blushed and shoved some "good-for-your-health" abyssal tonic at her; even the legendary, cold-blooded Demon Lord started climbing into her bed every night. Wait, they all seem to know who I am. Why aren't they burning me? Why are they all getting so close?! Flora looked down at the card in her hand, still glowing pink.

This is your fault! There's definitely something wrong with my Plant Spirit Card, hey!
