Weren't We Supposed to Escape? How Did I Become the Master of the Horror Story?

For the sake of a steady job, I sold myself to a monster containment facility.

The principal said that if I contained 100 SSS-rank urban legends, I'd regain my freedom.

The ghost whispering a spell to destroy the world: a cool, sharp-tongued ice queen who secretly helps me write my reports.
