#174 of 2D Dream Novels. The heroine with her sister is dedicated to fight against devils and to seal them. When outnumbered, or some relatives being captured as hostage, you know what is going on.
No entry on mugi database but a digital version is released 4 years after the physical one: http://www.dlsite.com/books/work/=/product_id/BJ004379.html
