I found my calling.

Seiko is not good at interacting with people. Her only pleasure is reading books. She knows that while she would prefer to continue living this way, she is not permitted to do so. One day, when she was thinking "at least just for now," an unbelievable event occurs. Seiko, who has little sense of ethics, and the demons who blindly follow her. This is a story of an ordinary(?) high school girl who will come to be feared in another world.
