(Gender-bender, 1v1 pure romance, not an overpowered protagonist story)
To take revenge, I sold my soul and gained immense power.
The price was becoming a vampire girl.
But for some reason, after being "tormented" for years by some awful person, I finally escaped the "demon's lair."
The first thing I did after escaping was seek revenge on the Holy Church.
Along the way, I even found a black-haired witch who had been imprisoned by the Holy Church and had only just managed to escape.
We set out together to take revenge on the Holy Church, but for some reason, that witch seemed to get closer and closer to me as we traveled.
"Ina, can you keep your distance? You're scaring me."
The black-haired girl, who had reached the highest position in the Holy Church, smiled faintly and held me tightly, never once taking her eyes off me.
"No can do, Cynthia. You're mine and mine alone, forever~"
The silly witch I picked up suddenly became a saintess, and she seems to have designs on me. What should I do?! Help! Anyone there?!
