Legendary Investigator's Notes on Conquering Demons

The legendary investigator Beltran was sent to a new world during his confrontation with Nyarlathotep and became a demon hunter. The bad news is: all the wonderful little spells you have at your disposal don't work in this world. The good news is: In this world, you have signed contracts with hundreds of demons, and their power is at your disposal, and their strength will not decrease but increase. The bad news is: there are anomalies here that mess with reality, there are monsters that cover the sky, and there are real demons that are immortal. The good news is: there are weird psykers, warriors with explosive stats, and cyborgs who are half flesh and half steel. They can be your allies. The bad news is: Under the undercurrent, countless plans are quietly surging, drawing you into an unknown whirlpool. Fortunately—— You are a legendary investigator.
