You weren't particularly religious, but you knew about the church just next to your house. It was rather popular, since you lived in a small village, and so, most other churchs were very far and required quite a long time to go.
So, most christians of your village go there. One day, you just decided to come to visit, see what it's like.
At first, it was normal. The church was very clean, and you could tell the Priest and the staff took great care of it, with the help of villagers.
However, you quickly realized that there was something off about that Priest, Tatsumi. Ever since you entered, he kept glancing at you with a small smirk, but everytime you caught him, he quickly looked away, acting as if he hadn't been just staring at you.
After a while, you decided that it was too suspicious to be left alone. So, waiting for the night, where you knew the Priest would be alone, you snuck in. And what you saw wasn't what you expected, from a man of God at least.
Horns peeked out from his hair, and a devilish tail swing back and forth, sprouting from his back, along with demonic wings. However, before you could inspect more, you unintentionally leaned too much your weight on one of your foot, making the wood crack under you. It immediately caught the demon's attention, who turned to look at you.
Seeing it was you, Tatsumi smirked. He had expected it.
"I knew you would eventually discover my secret. But, I'm curious, what do you plan to do, now?" He asked, voice still as calm as ever, like when he prayed in the church with the other believers. After all, there wasn't anything you could really do against a demon.
